How Can Digital Technologies Transform On-Campus Engineering Education?

New digital and online technologies have the potential to improve not just the quality of engineering courses, but their capacity to excite and engage students so they will be more likely to remain in science, technology, engineering and math fields.

hen the national media fervor over Massive Open Online Courses (MOOCs) reached its peak two years ago, I argued they were, in fact, not destined to be the magical elixir that would dramatically and instantly reduce the cost of a college education. Instead, I saw them as another tool for educators that might complement residential college education. Since then, the clamor has settled down, and we are, indeed, finding ways to make advanced educational technologies realize their potential to transform the quality of pedagogy and engineering education in general. Used wisely, these new digital and online technologies have the potential to improve not just the quality of engineering courses, but their capacity to excite and engage students so they will be more likely to remain in science, technology, engineering and math fields. This is important at a time when employers are starved for qualified graduates and engineering schools nationally are trying to retain students, particularly in the demanding first two years of the program. As highlighted in this issue’s cover story, more and more of our faculty are experimenting with these technologies in the classroom. They have enabled a change from the traditional lecture-followed-byhomework model. In several sections of our core required courses, students now are expected and motivated to engage the fundamental concepts of the lecture topic before class via carefully designed digital content, such as short videos and questions to assess initial understanding. They then look forward to solving problems during class time, typically in small groups seated around tables as both the instructor and a set of upper class learning assistants roam this new “studio” classroom offering guidance and answering questions. Early indications are that this approach is working terrifically. As educators, we are looking at two primary metrics to gauge the effectiveness of these new

techniques. One is student performance, and we are seeing that students are performing at least as well as—and in the cases of struggling students, much better than—they did in conventional classes. But even more important, I believe, is the shift in attitude we are seeing. Students are clearly more engaged in the studio classroom and are conveying an increased interest and enjoyment of these courses. All of this stands to benefit not just themselves, but also society, as students are more likely to stick with their engineering majors. We have also begun sharing our experiences with colleagues in other STEM departments at BU— such as math, physics, chemistry and biology— where our students take several of their courses. I believe students in other STEM fields have as much to gain from these new technologies as engineering students do. As with anything new, there are challenges associated with this approach; one is the technology itself. We need to improve the formats so faculty can use them comfortably and creatively without having to become IT experts. We will need faculty who are successful with these new technologies to mentor others and show them the way, while giving faculty the time they need to develop these courses. One of the more immediate challenges is creating the physical space the studio classroom requires. Packing students into neat, stadium-like rows is space efficient, but not conducive to peer learning and roving instructors. Converting conventional classrooms to the more effective studio format is now one of our fundraising priorities. I believe these challenges can and will be met. As with the best engineering, education requires us to push into new territory and use our experiences to improve. I believe that the future of engineering education will look much different, and produce more and better engineers ready to move our society forward.

Revolutionizing the eye exam

Professor Selim Ünlü (ECE, BME, MSE) (left) and Associate Professor John Connor (MED) have developed a rapid, chip-scale photonic device that can detect viruses, including Ebola, on site.

BU TEAM’S DEVICE DETECTS VIRUS QUICKLY AND ON SITE

ne of the big problems hindering containment of Ebola in the current epidemic is the cost and difficulty of diagnosing the disease when a patient is first seen. Conventional fluorescent label-based virus detection methods require expensive lab equipment, significant sample preparation, transport and processing times, and extensive training to use. One potential solution may come from researchers at the College of Engineering and the School of Medicine, who have spent the past five years advancing a rapid, labelfree, chip-scale photonic device that can provide affordable, simple and accurate on-site detection. The device could be used to diagnose Ebola

and other hemorrhagic fever diseases in resource-limited countries. The first demonstration of the concept, described in the American Chemical Society journal Nano Letters in 2010 and developed by Professor Selim Ünlü’s (ECE, BME, MSE) research group in collaboration with Professor Bennett Goldberg (Physics, BME, ECE), showed the ability to pinpoint and size single H1N1 virus particles. Now, after four years of refining the instrumentation in collaboration with Associate Professor John Connor (MED) and other hemorrhagic fever disease researchers at the University of Texas Medical Branch, the team has demonstrated the simultaneous detection of multiple viruses in blood serum samples—including viruses genetically modified to mimic the behavior of Ebola and the Marburg virus. Mentioned in Forbes magazine as a potentially game-changing technology for the containment of Ebola, the device identifies individual viruses based on size variations due to distinct genome lengths and other factors. Funded by the National Institutes of Health, the research is showcased in ACS Nano. “Others have developed different label-free systems, but none have been nearly as successful in detecting nanoscale viral particles E N G I N E E R S P R I N G 2 0 1 5 W W W.

in complex media,” said Ünlü, referring to typical biological samples in which a mix of viruses, bacteria and proteins may be present. “Leveraging expertise in optical biosensors and hemorrhagic fever diseases, our collaborative research effort has produced a highly sensitive device with the potential to perform rapid diagnostics in clinical settings.” Whereas conventional methods can require up to an hour for sample preparation and two hours or more for processing, the current Boston University prototype requires little to no sample preparation time and delivers answers in about an hour. “By minimizing sample preparation and handling, our system can reduce potential exposure to healthcare workers,” said Connor. “And by looking for multiple viruses at the same time, patients can be diagnosed much more effectively.” The shoebox-sized prototype diagnostic device, known as the Single Particle Interferometric Reflectance Imaging Sensor (SP-IRIS), detects pathogens by shining light from multi-color LED sources on viral nanoparticles bound to the sensor surface by a coating of virus-specific antibodies. Interference of light reflected from the surface is modified by the presence of the particles, producing a distinct signal that reveals the size and shape of each particle. The sensor surface is very large and can capture the telltale responses of up to a million nanoparticles. In collaboration with BD Technologies and NexGen Arrays, a BU Photonics Center-based startup run by longtime SP-IRIS developers David Freedman (EE, PhD’10) and postdoctoral fellow George Daaboul (BME, PhD’13), the research team is now working on making IRIS more robust, field-ready and fast—ideally delivering answers within 30 minutes— through further technology development and preclinical trials. SP-IRIS devices are now being tested in multiple labs, including a Biosafety Level-4 (BSL-4) lab at the University of Texas Medical Branch that’s equipped to work with hemorrhagic viruses. Other tests will be conducted at BU’s National Emerging Infectious Diseases Laboratories (NEIDL) once the facility is approved for BSL-4 research. Based on the team’s current rate of progress, a field-ready instrument could be ready to enter the medical marketplace in five years. 4

EPIC Design Studio Named for Lorraine A. Tegan college of engineering dean kenneth r. Lutchen welcomed John Tegan (MFG’88) and several members of his family to campus on November 24 for the dedication of the design studio in the Engineering Product Innovation Center (EPIC) in honor of Tegan’s mother, Lorraine A. Tegan. Noting that Tegan recently made a substantial gift to the College, Lutchen said, “John Tegan’s support for EPIC and the College of Engineering will impact literally every undergraduate who comes through the College for many years to come. All undergraduates will work in the Lorraine A. Tegan Design Studio during their time here.” Tegan, who serves on the Dean’s Leadership Advisory Board, said, “My mother, Lorraine Tegan, was a lifelong educator and mathematician. Supporting EPIC is a wonderful way for me to honor her memory and all that she meant to me.” EPIC opened earlier this year as a cuttingedge facility that allows students to learn the entire concept-to-deployment innovation process. At EPIC, students can develop their

ENG Grads Pursue Internships With New Engineering Practice Option the college of engineering has introduced a new Engineering Practice option for Master of Science (MS) and Master of Engineering (MEng) students in all concentrations. Students may now add the designation— which is widely recognized by employers and research institutions— “with Engineering Practice” to their degree by completing an approved internship in their field of study. The Engineering Practice option recognizes the power of combining rigorous academic coursework with supervised

ideas for new products, design them, create prototypes and learn the advanced manufacturing process. The Lorraine A. Tegan Design Studio will serve as the space where students can work out their design ideas using paper and pencil or computers. John Tegan is CEO of Communication Technology Services (CTS), a Marlboro, Massachusetts-based leader in the design, engineering and installation of distributed antenna systems. For more than two decades, he has helped transform CTS from a small family business into a national telecommunications services corporation with more than 500 employees. More than 5,000 CTS systems can be found in hospitals, hotels, college campuses, stadiums, theme parks, government buildings, airports and other venues across the country. —michael seele College of Engineering Dean Kenneth R.

real-world research or industrial applications. Participating students enhance classroom learning with practical experiences that enable them to both develop and apply technical, project management and leadership skills. The new designation formalizes and recognizes graduate-level internships, which several engineering students have pursued in recent years. Some, like Abhinav Nair (MEng’14), who last summer helped develop a major, new online educational curriculum for the educational publisher Pearson, have parlayed internships into full-time jobs. “My internship helped me transition from being a student in a nest to spreading my wings as a professional engineer,” said Nair. “I wouldn’t think twice before recommending it to my peers.”—jan smith for more information, visit bu.edu/ eng/academics/masters/internships.

BU-Brigham and Women’s Hospital Partnership Celebrates First Year JOINT RESEARCH FOCUSED ON LESS INVASIVE, MORE ACCURATE MEDICAL IMAGING AND IMAGEGUIDED INTERVENTIONS

PHOTOGRAPHS COURTESY OF BRIGHAM & WOMEN’S HOSPITAL

oston University College of Engineering Assistant Professor Darren Roblyer (BME) and Brigham and Women’s Hospital radiologist Srinivisan Mukundan are exploring a strategy that combines a new optical imaging device developed by Roblyer with emerging magnetic resonance imaging (MRI) techniques to probe malignant brain tumors during chemotherapy treatment. Their research could enable clinicians to monitor the effectiveness of chemotherapy over the course of treatment and implement changes to chemotherapy drugs and dose levels as needed. The project is one of five now receiving funding through an ongoing partnership between Boston University and Brigham and Women’s Hospital. On September 12 at the BU Photonics Center, Dean Kenneth R. Lutchen and Dr. Steven Seltzer, Chair of the BWH Department of Radiology, announced the second year of the partnership, which has already provided one year of seed funding to projects ranging from image-guided cancer drug delivery to early detection of heart disease. “The goal is to leverage synergies between the Brigham and Women’s Hospital Radiology Department’s expertise in imaging and image-guided interventions and the College of Engineering’s strengths in developing new materials and technologies as well as novel techniques for processing images and large data sets,” said Associate Professor Tyrone Porter (ME, BME, MSE), who is coordinating

(AMIGO). Joint research between the two campuses could result in less invasive, more accurate medical imaging and image-guided interventions. First-round projects include the engineering of a new “molecular imaging” MRI contrast agent for detecting early calcification of the aortic valve; the combination of ultrasound and MR data to evaluate the elastic properties of tissues, which are associated with pathological indicators of disease; a clinical decision support system for patient-specific cancer diagnosis and management; and ultrasound-guided delivery of chemotherapy drug-laden nanoparticles to metastasized lung cancer cells in the brain. Applications for second-round projects are now underway. Participating ENG faculty include Professors Joyce Wong (BME, MSE), Paul Barbone (ME, MSE), Venkatesh Saligrama (ECE, SE) and Yannis Paschalidis (ECE, SE); Associate Professor Porter; and Assistant Professor Roblyer.

METHOD COULD SPUR NEW APPROACHES TO DISEASE

ell traction forces, or the tugging of individual cells on their immediate environment, play an important role in fundamental biological processes such as cell division, differentiation and migration, and more complex ones such as embryonic development and inflammation. When receptors on the cell surface called integrins adhere to the cell’s surrounding network of protein scaffolding known as the extracellular matrix, the forces they exert signal to the rest of the cell that important cellular processes are underway. Measuring those forces over time could reveal more about the inner workings of normal and abnormal cellular development, and enable clinicians to more effectively diagnose and treat cancer, scarring and inflammation. Overcoming several limitations of conventional approaches, a new method developed by Professor Christopher

determining the most effective treatment for a bacterial infection can take several days as clinicians culture bacteria from a sample of the infected site, test their response to different antibiotics, and home in on the best choice. Meanwhile, patients receive broadspectrum antibiotics that could be far less effective, leaving them prone to spreading the infection and generating antibiotic-resistant bacteria. Now, a new technique developed and evaluated by a team of researchers from the Boston University College of Engineering, 6

Chen (BME) and collaborators at several institutions—including Harvard University, Stanford University, University of Pennsylvania, the Wyss Institute for Biologically Inspired Engineering, and the Howard Hughes Medical Institute (HHMI)—promises to measure cell traction forces at unprecedented resolution in space and time. The researchers described and demonstrated this advance in the online edition of Nature Methods. “Traditional methods that rely on watching cells pull on soft, synthetic materials could only resolve these forces at the micron or cellular scale, but the new method can do so at the nanoscale level where individual integrins adhere to the extracellular matrix, enabling researchers to obtain a much clearer picture of these forces,” said Chen, a world leader in tissue engineering and mechanobiology, the study of how physical forces and changes in cell or tissue mechanics contribute to development, physiology and disease. TP Fluorescein

Stress

With funding from the National Institutes of Health and HHMI, the research team engineered a new class of cell traction force probes consisting of single strands of DNA shaped as hairpins of different lengths and DNA sequences—each tuned to unfold when subject to a specific amount of force, and attached to a light-emitting fluorophore (a fluorescent chemical compound) and a “quencher” that effectively dims the fluorophore’s emitted light. When a cell’s integrin pulls on the extracellular matrix (ECM), the force that it exerts causes one of the DNA hairpin probes to unfold, thereby separating the quencher from the fluorophore and freeing it to emit light. Based on the intensity of this light, a microscope measures the forces exerted by clusters of integrins at each site where a cell adheres to the ECM, and shows how these forces are distributed throughout the cell. As microscopy advances, the new method will enable measurement of cell traction forces at the single integrin level as well. 8 6

Stanford University School of Medicine and Virginia Tech may ultimately reduce antibiotic susceptibility testing time to a matter of minutes and thus enable more precise and effective prescriptions. The technique centers on a silicon microcantilever designed by Professor Kamil Ekinci (ME) that’s sensitive enough to reveal whether or not onboard bacteria—captured on the surface by a chemical that bonds to their cell walls—are still “alive and kicking” rather than stilled forever by a successful antibiotic. A laser beam continuously reflects off the surface, indirectly detecting subtle, low-frequency vibrations of the diving boardlike cantilever that are caused entirely by bacterial motion. In recent experiments funded by the National Science Foundation and National

Institutes of Health, the researchers attached a layer of E. coli bacteria to the cantilever, applied the antibiotic streptomycin and observed a cessation of bacterial motion within 30 minutes. They published their results in the journal Applied Physics Letters. The study introduces a new platform for improving our understanding of the mechanisms behind the motion of and communication among microorganisms—key factors in bacterial infections and antibiotic resistance— and for developing a disposable, microfluidic chip to diagnose bacterial infections and pinpoint suitable antibiotics. “Ultimately, the cantilever and optical measuring instruments could be incorporated into a compact, user-friendly device that clinicians could use to test a patient’s bacteria sample for antibiotics susceptibility,” said Ekinci.

MSE’S DAVID BISHOP OFFERS ROAD MAP IN PHYSICS TODAY COVER STORY

bu researchers envision mass-producing high-speed nanoscale devices ranging from integrated circuits to biosensors, but their aspirations have been hampered by a persistent inability to precisely manipulate nanomaterials to build reliable, functional products at a reasonable cost. In a nutshell, the key challenge has been to pattern extremely small materials at exact locations in a repeatable manner over relatively large surfaces—all within a very short time frame. Current nanomanufacturing processes are likely to become wasteful and/ or expensive if applied on a commercial scale, potentially costing orders of magnitude more than the value of the devices or systems they’re designed to build. “Absent major breakthroughs in nanomanufacturing, the current trend in smartphones, laptops, PCs and other electronic devices toward smaller, faster, better and cheaper models may grind to a halt,” says MSE Division Head and Professor David Bishop (ECE, MSE, Physics). But Bishop is confident that with sufficient investment, nanomanufacturing can evolve from a laboratory technology to one capable of generating commercial products on a massive scale within the next decade or two. In the December 2014 Physics Today cover

story, he and coauthor Matthias Imboden, an ECE postdoc, explored three potential pathways—each requiring further research to overcome current limitations—to the highspeed, low-cost and scalable manufacture of devices with nanoscale features. They include resist-based nanolithography, a nanoscale version of photolithography, commonly used today in the manufacture of semiconductor devices. This technique passes light, x-rays or electron beams through a mask in which the features or holes are on the order of one-billionth of a meter, resulting in similarsized features on the manufactured device layer. The second approach is nanoimprinting or nanostamping, a process akin to using a nanoscale rubber stamp, and could be ideal for manufacturing memory chips and magnetic displays. The third strategy is to apply a direct writing technique, controlling the placement of atoms with nanoscale precision. An example of this is dip-pen lithography, which deploys atoms at precise locations on a device surface just as a ballpoint pen’s inkball deposits ink on a piece of paper. Another direct writing technique invented by Bishop at BU, atomic calligraphy, effectively spray-paints atoms at desired locations on a surface through precisely positioned holes in a mask. “This is not a one-size-fits-all proposition,” he said. “One technique will probably not end up ‘the winner,’ but they’ll all have regions of optimal applicability. Nanomanufacturers of the future may place different technologies on a chip that can be activated at different times to achieve different purposes.”

downtyme, a startup co-founded by barron Roth and Luke Sorenson (both CE’16) based on their final project in ENG EC 327, Introduction to Software Engineering, won the second annual Beantown Throwdown entrepreneurial business pitch competition. Held on November 18 at Boston’s District Hall and organized by the MIT Enterprise Forum, the competition featured three-minute pitches from local college student entrepreneurs. Edging out teams from Harvard, MIT, Northeastern and five other Boston-area colleges and universities vying for votes from a sellout audience of more than 400 students, sponsors and investors, Downtyme received more than $20,000 in in-kind legal and marketing services, mentoring and office space.

microbes are all around us—even inside us—and that’s a good thing. Left alone, these tiny organisms have a huge impact on everything from human health to wastewater treatment. But with a little engineering, they could do even more. In certain environments, their metabolic processes could be exploited to make biofuels, vaccines and other useful products and services. To tap their potential, Associate Professor Daniel Segrè (Biology, BME, Bioinformatics) and collaborators have developed mathematical models to both predict the metabolic interactions that occur among different microbial species under varying environmental conditions, and to design new microbial networks with desired properties. Segrè presented his research at the first Symposium on the Control of Network

traffic congestion is a waste of time, energy and money. In 2011, it caused Americans in metropolitan areas to spend 5.5 billion extra hours on the road and pump 2.9 billion extra gallons of fuel into their gas tanks, with associated costs reaching $121 billion—a nearly sixfold increase since 1982. Municipalities have attempted to mitigate traffic congestion through highway on-ramp metering and fees at peak travel times, but the problem continues to worsen. Now a research team led by Professor Calin Belta (ME, SE) and University of California, Berkeley Associate Professor Murat Arcak (EECS) is advancing a novel solution that could considerably reduce traffic congestion.

Systems (SCONES) on October 27-28 in the Photonics Center Colloquium Room. Sponsored by the IEEE Control Systems Society and the Center for Information and Systems Engineering at Boston University, SCONES celebrated the inaugural March 2014 issue of the IEEE Transactions on Control of Network Systems (TCNS), a new IEEE Transactions journal edited by Professor Yannis Paschalidis (ECE, BME, SE) focused on problems related to the control, design, study, engineering, optimization and emerging behavior of network systems. “We live in a world that is extremely interconnected,” said Paschalidis, the journal’s editor-in-chief. “This is also true of systems, biological or manmade, that support our modern way of life. Networks, which both connect system components and influence how they function as a whole, are increasingly the focus of leading-edge research, and this is the impetus for TCNS and SCONES.” One author of each paper in the inaugural issue presented at the symposium, along with talks and posters from several other researchers in the field. Representing major research institutions from around the world, SCONES presenters explored the analysis,

from the National Science Foundation, the researchers plan to develop algorithms for a data-driven traffic management software system that optimizes the timing of traffic lights at both highway on-ramps and roadway intersections in real time. The work represents a novel application of “formal methods,” a discipline within computer science focused on efficient techniques for proving the correct operation of systems ranging from computer programs to digital circuits, thus ensuring their reliability and robust performance. “We want to develop a system in which we can guarantee specifications for traffic networks just as we do for computer programs,” said Belta. “These specifications will include

Whereas current systems reduce traffic congestion within small networks of freeways and arterial roads, this approach promises to do so across much larger networks.

control and optimization of communication, transportation, electric power, biological, social and other networks. Bringing the TCNS journal to life, the 23 featured speakers—including Professors Christos Cassandras and Lev Levitin (both ECE, SE) addressing challenges in resource allocation and routing—illustrated complex concepts with a flurry of equations, algorithms, graphs and diagrams. “SCONES is playing a key role in coalescing a community of researchers around the journal,” said Paschalidis.

minimizing traffic jams and maximizing the flow of traffic, all while ensuring that pedestrians don’t have to wait a long time to cross the street.” Whereas current systems reduce traffic congestion within small networks of freeways and arterial roads, this approach promises to do so across much larger networks. In their algorithms, the researchers plan to partition a large road network into small sub-networks and establish specifications so that enforcing desired traffic patterns in small sub-networks (and on roads linking one sub-network to another) guarantees desired traffic patterns in the original network. The proposed techniques will be tested in current and upcoming traffic management projects in California sponsored by Caltrans, the state transportation agency. Applications include a prototype decision support system to be deployed along the Interstate 210 corridor north of Los Angeles, and coordinated ramp metering, arterial intersection and variable speed limit management on a freeway in Sacramento and a freeway-arterial interchange in San Jose.

Vision Quest TWO BU GRADS SEEK TO REVOLUTIONIZE THE EYE EXAM

ccording to the World Health Organization, about 90 percent of the world’s visually impaired people live in low-income settings and often there are no eye doctors or eyeglasses available. In Rwanda, for example, there are about 10.5 million people—and 14 vision specialists. Without access to an eye exam or glasses, simple nearsightedness becomes debilitating. Now two ECE graduates, Yaopeng Zhou and Marc Albanese, are trying to change those bleak statistics. They’ve invented a handheld device called Smart Vision One (SVOne) that scans a person’s eyes, instantly determines whether he or she needs glasses, and decides what their prescription should be. Bolstered by a $1 million, 2013 Powerful Answers award from Verizon, their company, Smart Vision Labs, is poised to start manufacturing and delivering SVOne devices this year. “This could be big,” said Professor Thomas Bifano (ME, MSE), director of BU’s Photonics Center, who advised both Zhou and Albanese on their theses at BU and now serves on their board of directors. “If this catches on, it could be so cheap that

everyone has one, like a thermometer. It has the potential to be hugely disruptive.” The device is a small block of plastic (a little larger than a deck of playing cards) that slips over an iPhone. To perform an exam, one person holds the device up to a patient’s eye and presses a button. Light shines into the patient’s eye, bouncing off the retina and back out the front of the eye. Curves and imperfections in an eye will cause beams of light to bend, bouncing out of the front at slightly different angles. A sensor collects this information, the computer in the iPhone interprets it, and the result is a prescription specific to that eye. Traditionally, optometrists have determined eyeglass prescriptions by asking patients to look through a phoropter, a bulky device on a swivel arm containing multiple lenses. A patient looks through lenses of different strengths and reports which ones make his or her vision the sharpest. “It’s a big, clunky, subjective measure,” said Albanese. “What we have is a small, portable device that offers you an objective number. It gives you the answer! All you have to do is look straight.” The device costs $3,950 including an iPhone, a bargain compared to other similar devices on the market that go for between $15,000 and $40,000. “I’m really excited to see this thing go,” said Bifano. “These two guys took what we taught them at BU and just ran with it. It’s been a thrill for me to see them build something from scratch. They just buckled down and made it happen.”—barbara moran, bu research

MEng Student Develops Wheelchair Health Monitoring Device a man in a wheelchair is home alone when he accidentally maneuvers too close to a staircase. One wheel passes over the edge of the top stair, and the wheelchair teeters on the brink. Instinctively, the man jerks his arms upwards to regain balance, but he can’t. He and the heavy wheelchair tumble down the steps. Fortunately, the wheelchair and the man are connected to a device that transmits information through the internet to the man’s health care provider.

The team linked the wheelchair to the “Internet of Things” by developing technology that attaches to the chair and the user to collect and send information. The device can monitor fluctuating physiological and mechanical data such as heart rate, skin temperature and chair orientation and battery power, and transmit it to a health care provider via an Internet application. It also includes a geo-location monitor enabling users to find wheelchair-accessible venues. The new technology has received press coverage around the world, including praise from world-renowned physicist Stephen Hawking.

Rocket Propulsion Group on a Mission UNDERGRADS AIM TO MAKE BU THE FIRST UNIVERSITY TO LAUNCH A ROCKET INTO SPACE

orking long hours in the basement of 110 Cummington Mall, the Boston University Rocket Propulsion Group’s (BURPG) 35 undergraduates—33 from the College of Engineering, one from the College of Arts & Sciences and one from the College of Communication—are designing, building, testing and publicizing Starscraper, a 30-foot-long, 12-inch-diameter rocket designed to propel a 100-pound payload into space and land it safely back on Earth. Assembly and testing is planned for the Spring 2015 semester, with a tentative launch date in July in Nevada’s Black Rock Desert. If all goes well, Starscraper will be the first university-based rocket to breach 10

the 100-kilometer altitude Kármán Line, commonly regarded as the border between Earth’s atmosphere and outer space. BURPG will also become the first nongovernmental and non-corporate entity to do so using a hybrid propulsion system, in which solid fuel reacts with a liquid oxidizer— a combustive mix that provides sufficient thrust to get the rocket off the ground. The current BU system consists of a six-segment structure made of tire rubber (the solid fuel) and a tank of nitrous oxide (the liquid oxidizer), commonly used to sedate dental patients. Its payload will include a GPS tracking system, but future versions could carry everything from telescopes to drug manufacturing experiments into space.

An amateur rocket enthusiast who launched several small-scale rockets before he arrived at Boston University, Armor Harris (ME’15) wowed the judges at the College of Engineering’s first Imagineering Contest with a sounding rocket designed to reach a 100,000-feet altitude that he had partially built in the Imagineering Lab. In many ways, Starscraper is a follow-up to this achievement and the capstone of three years helming the BURPG. Funded in part by GE, Raytheon, FloDesign and SpaceX, and donations through the ENG Annual Fund and the group’s own Kickstarter crowdfunding site, the BURPG rocket is about 10 times cheaper to develop than a comparable NASA hybrid rocket. Several BURPG members have netted internships or job offers from the three corporate sponsors and other companies in the spaceflight industry, including Harris, who is on his second internship as a propulsion development engineer with SpaceX. More importantly, participants are gaining invaluable experience in hands-on engineering, building a solid foundation for their entire careers. “In the classroom, students can learn how to derive Bernoulli’s equation (which governs fluid flow in pipes), but down here they can build a high-pressure fluid system,” said Harris. “The real value of this mission is that it can serve as a model for engineering education in which students apply theoretical concepts as they learn how to design, build, test and integrate components of a working system.” follow the bu rocket propulsion group’s progress on this mission at burocket.org.

A Paper Strip Test for TB? BME POSTDOC DEMOS PROMISING PORTABLE DIAGNOSTIC

iagnostic tests for tuberculosis (TB) usually involve chest x-rays, which require heavy, expensive equipment, or phlegm samples, which can take weeks to culture. In resource-limited countries where TB is endemic, such tests are hard to come by outside of major cities, leaving health care workers with few good options. The simplest is a TB test that works like a home pregnancy test, which diagnoses the disease based on the detection of lipoarabinomannan (LAM), a biomarker for TB

present in the urine of TB-infected individuals. Although the test is cheap, easy to use and can be administered at the point of care, it produces accurate results only for patients who are also infected with HIV, since LAM is more abundant in their urine. Now Sharon Wong, a postdoctoral fellow in Professor Catherine M. Klapperich’s (BME, ME, MSE) lab, is working toward a similar, inexpensive user-friendly test that can overcome this limitation and serve the general TB population at point of care. By applying heat to a strip of chromatography paper dipped in a urine sample, the device would concentrate LAM while evaporating most of the liquid sample. As a result, the low levels of LAM in non-HIV patients’ urine, which don’t register in the commercially available test, are increased and can be more easily detected. Described in November in the American Chemical Society journal Analytical Chemistry, the new test is the first to demonstrate the use

Scaling Up Synthetic Biology ECE RESEARCHERS DEVELOP POWERFUL NEW SOFTWARE TOOLS

in the past 15 years, synthetic biology researchers have rewired and reprogrammed genetic “circuits” in living cells and organisms to enable them to perform specified tasks, both to improve our understanding of biology and to solve critical problems in health care, energy and the environment, food safety, global security and other domains. While practitioners dream of engineering each new organism as expeditiously as today’s new

mobile phone apps are produced, serious obstacles remain. Genetic parts are hard to find and tune, the final behaviors of engineered organisms are difficult to predict, and few tools exist that can handle the scale and complexity of the enterprise. Recently, however, two researchers at the College of Engineering, Assistant Professor Douglas Densmore (ECE, BME, Bioinformatics) and Research Assistant Professor Swapnil Bhatia (ECE) have joined forces to streamline synthetic biology from concept to design to assembly, encoding solutions in a rich suite of software tools. In a paper published in Nature Biotechnology, they and collaborating researchers at MIT showed how their tools can be used iteratively to help synthetic biologists specify, analyze and

of heat on a paper-based device for the purpose of quickly concentrating biological material for clinical analysis. Wong developed the test in collaboration with Klapperich, Research Assistant Professor Mario Cabodi (BME) and Jason Rolland, the former director of research at Diagnostics for All, a Cambridge-based nonprofit. “This protocol that Dr. Wong has developed has the potential to increase the utility of one of the most simple and inexpensive methods to detect TB,” said Klapperich. “Strip tests are easy to use and understand and could positively impact patient care in many lowresource settings.” In lab tests, Wong diluted a small quantity of LAM in a sample of synthetic urine in a beaker and inserted one end of a piece of chromatography paper into the sample. The urine wicked up the paper until it reached the other end, which was warmed to 220 degrees Celsius by an electric heater. Most of the urine evaporated off within 20 minutes, leaving a concentrated amount of LAM at the tip of the paper strip. Using an antibody that binds to LAM, Wong then determined that the biomarker was 20 times more concentrated at the tip than at the end submerged in the sample. “I can now envision, in the foreseeable future, a TB diagnostic that can be used on anyone, by anyone, anywhere in the world,” said Wong, who next plans to optimize the system, validate it on clinical samples and identify batteries and other power sources to make it portable.

improve large-scale designs for engineered biological organisms. The researchers, who were funded by a $3.6 million Defense Advanced Research Projects Agency (DARPA) grant, demonstrated the first instance in which synthetic biologists ported a large gene cluster from one organism into another. It’s a process Bhatia likens to persistently tinkering with an app that runs on an iPhone to make it work on a Kindle, and believes will pave the way for many synthetic biology applications. Densmore and Bhatia are now focused on developing software that will automatically learn biological design rules, propose genetic circuit designs, plan DNA assemblies and automate much of the pipetting labor involved in the assembly of engineered biological systems.

t the front of one classroom in the Photonics Center, instead of a lecturer or PowerPoint presentation there’s just an old-school wall clock whose hands sweep out 120 minutes while students essentially conduct the class from their seats.

Collaborating with their peers at 10 clusters of rectangular tables in this well-lit, oblong “learning studio,” and guided by Assistant Professor Stormy Attaway (ME) and three learning assistants (specially trained undergraduate teaching assistants), 75 students in EK127: Introduction to Engineering Computation solve computer programming problems that apply concepts from online course videos that they viewed from the comfort of their dorm rooms and apartments. Some problems are chosen based on common trouble spots pinpointed via mandatory quizzes that accompanied the videos. Students share their work on whiteboard-painted walls (slated to be replaced by electronic whiteboards by Fall 2015) and with Attaway and her learning assistants, who dart from table to table throughout the two-hour class. “I’m constantly roaming around the room,” says Attaway, who has spent most of her academic career standing in front of amphitheater-style lecture halls, directing her remarks at the average student rather than tailoring them for individual students. “I’m now talking to every student multiple times per class, and student engagement is through the roof.” Welcome to the flipped classroom, College of Engineering-style. Rather than delivering a lecture to row after row of students dutifully taking notes, with little or no interaction between lecturer and note-takers, and then assigning problem sets for students to solve at home—the model for science and engineering for more than a century—Attaway is leveraging leading-edge digital learning technologies to essentially do the opposite. So far she’s found the approach has paid off, yielding substantial improvements in student engagement, understanding and performance. EK127 blends the best of the virtual world—state-of-the-art web hosting and video production technology from edX, a nonprofit online platform offering Massive Open Online Courses (MOOCs) from Boston University and other member institutions—and the residential classroom, where dedicated faculty and teaching assistants guide students through the problem-solving process. The goal is to enhance the quality and value of the undergraduate engineering learning experience on campus. “Blended learning” experiments like this one are revolutionizing engineering education, and Boston University, which launched its Digital Learning Initiative (DLI) in 2013 to spearhead 14

innovative projects in online learning at all of its schools and colleges, is fully on board. Last year the DLI awarded $80,000 to fund a College of Engineering proposal to enhance EK127 and another core undergraduate engineering course, EK307: Electric Circuits, with a suite of online technologies and techniques. In both courses, instructors and teaching assistants funded by the DLI grant have developed online content not as a vehicle, like MOOCs, to reach large numbers of students via the Internet, but rather as a tool to free up precious time to focus on the application of knowledge in the classroom. Professor Thomas Little (ECE, SE), the College of Engineering’s associate dean for Educational Initiatives, sees these and other

“I’m constantly roaming around the room,” says Attaway. “I’m now talking to every student multiple times per class, and student engagement is through the roof.” ongoing pilot projects as part of a broader College-wide effort to combine the most effective active learning techniques with the latest digital learning technologies—from tablets to MOOCs—to bring engineering education into the 21st century. “Inspired by the success of these technologies in other disciplines and energized by the support and training DLI is providing, we are developing new ways to improve what’s important to the student: learning, retention and career preparation,” says Little, who heads a team of seven ENG faculty members spearheading digital learning innovations at the College. Little walks his talk. After teaching EC/ME/SE 544: Networking the Physical World the conventional way for five years, he flipped it two years ago, replacing lectures with active learning modules and hands-on challenges that develop and apply concepts assigned as preparatory exercises. The course is comprised of eight challenges of increasing complexity, leading to the demonstration of self-driving cars that navigate the fourth floor of the Photonics Center using wireless communications and indoor positioning technology. “Restructuring the course in a blended learning format has enabled students to have more time in class to solve problems and develop working systems that demonstrate their command of the theory,” he says. In effect, Little, Attaway, Horenstein and other innovative ENG faculty are reengineering their courses so that their students can spend more time practicing engineering.

EK127: STORMY ATTAWAY

EK127: REPLACING PASSIVE LEARNING WITH PROBLEM SOLVING Attaway, who in 2014 received the Metcalf Cup and Prize, Boston University’s top teaching honor, has been gradually flipping the course over the last three years. Supported by DLI funding, she produced course videos using Camtasia as the screen capture technology, and, thanks to “course builder” Declan Bowman (BME’15)— one of the first students in the College’s STEM Educator-Engineer Program (STEEP)—posted them on the webhosting platform edX edge. With all course content (documents with goals for each class meeting, short videos and questions to assess student understanding of the material) placed online, class time is now exclusively reserved for active learning in Photonics Room 117. In the spring of 2014, Attaway began flipping the course in its usual amphitheater-style classroom, testing out the approach in one of the course’s three sections. A student in the experimental section, Lauren Etter (ME’17), found that the combination of online lectures and active learning in

the classroom enabled her to grasp the course material much more effectively than the traditional method. “When studying for a quiz or exam, it was easy to go back to the videos and refresh what I had learned without having to rely on notes, which may not have been entirely correct. In addition, working with other people in the classroom helped me to learn the material more thoroughly. For example, when I was struggling to understand graphical user interfaces, the other students in my group helped clear up my misunderstandings, and when all three of us got stuck, the learning assistant was there to help us.” Continuing her experiment into the summer, Attaway invited a class of 23 EK127 students to go online and view the first course module (four to five approximately seven-minute lecture videos, primarily consisting of PowerPoint slides with a voice-over by Attaway) before coming to the first class meeting. Once in the classroom, students gathered at small round tables and worked on three or four assigned problems, first as individuals and then in groups of three as a graduate teaching fellow and several teaching assistants milled about, sitting with groups as necessary to explain concepts ranging from data structures to numerical methods. “The students were actively engaged from the beginning,” says Attaway. “The peer-to-peer instruction worked very well. On a scale of 1 to 5, with 1 being “not at all” and 5 being “very,” the average response on how much the group in-class exercises enabled them to learn was 4.5. Of the 23 students, 16 earned grades in the A range, 6 in the B range and one in the C range, and there were no D, F, or W grades. In my opinion, the class was a smashing success.” Building on that success and adding more learning materials for the course site on edX edge, Attaway has now delivered essentially the same experience to her 225-strong Fall 2014 class (three sections of approximately 75 students each) in the new, more flexible Photonics 117 studio space. Compared to the Spring 2014 class, where only one-third of the students learned in a partially flipped classroom, the average grade point average rose from 2.9 to 3.6, and average attendance increased from 89.8 to 95.2 percent. Chris Mullen (ME, MS’15), who has served as a learning assistant for EK127 for the past three semesters, has seen a dramatic improvement in class preparedness since Attaway started flipping the course. “In previous semesters, students would be required to complete a reading assignment before coming to lecture, and then lectures would present material covered by the reading. By halfway through the semester, most students would decide that they could get away without doing the reading and just listen to lecture, so instead of having the lecture to ask questions and clarify their understanding of the material, they were hearing everything for the first time. Because the students are now watching the videos and getting the ‘lecture’ before class time, they have time to figure out what they don’t know, and what to ask.” EK307 AND EK210: FREEING UP TIME FOR HANDS-ON ENGINEERING Supported by DLI funding, Professor Mark Horenstein (ECE) has developed a series of 30-minute course modules on circuit analysis and design to prepare EK307 students for the course’s weekly lab. 16

BU COLLEGE OF ENGINEERING

Always available to students and consisting of animated, voice-over PowerPoint lectures and lab demonstrations produced with Camtasia and uploaded to a video hosting service, the modules function as tutorials that present essential concepts and practical information to help students get the most out of each lab. In the course, students design and construct circuits and test their results in the ECE Department circuits and electronics teaching facility. Aside from a basic introduction they get in their physics classes, this is the first course in which they are immersed in the details of circuit design, and the amount of material they’re expected to absorb can be daunting. The lab videos help students to master often-complex concepts, illustrating them with images, diagrams and schematics.

The modules function as tutorials that present essential concepts and practical information to help students get the most out of each lab. “Mark’s videos have been a hit with our students,” says Aleks Zosuls, the course’s lab instructor. “Even without Mark physically in the lab, his voice emanates from speakers and headphones as students use the videos in a self-paced manner to help them with their lab work. It’s like having a personal TA over your shoulder while working, with the added benefit that you can pause the video while you digest an aspect of the material.” “The videos have been helpful in giving you an overview of what your circuits might look like before you get to the lab,” says EK307 student Fritz Jolivain (EE’17). “They’ve helped me feel more confident in translating a circuit to a breadboard to see how it works.” Another College of Engineering course using videos to prepare students for hands-on engineering is EK210: Introduction to Engineering Design, a two-credit class aimed at giving sophomores a basic understanding of how to develop a product from concept through design and deployment. Meeting in the Engineering Product Innovation Center’s (EPIC) Lorraine A. Tegan Design Studio, students work in multidisciplinary teams with time and budget constraints on externally sponsored design projects. By viewing web-based lectures at home on topics concurrent with specific phases of the projects rather than receiving this information via in-class lectures, students are able to devote most of their class time to working on their projects in the design studio. “We’re trying to teach students hands-on engineering design, but we only have them two hours a week,” says EK210 instructor and

what does it all mean? The performance in the sections with an active learning format was higher for all assignments and semesters.

Professor of the Practice Gerry Fine (ME), who directs EPIC. “When we started working on the course we assembled an ad hoc committee and quickly came to the realization that flipping the classroom was the best way to solve the problem.” Produced using Echo 360 and hosted by BlackBoard Learn, each online module contains about an hour of required video material consisting of five to six segments of about 10–12 minutes each delivered by Fine, other ENG faculty or sourced externally, and one or two brief quizzes to ensure the material is understood. Students then implement what they learned in the Tegan Design Studio while Fine and his teaching assistants roam the room to respond to individual and team questions as they arise. Hannah Zengerle (ME’17) found the online videos useful in covering topics that didn’t get addressed in class. “For our first project involving reverse engineering, the presentation itself was about half of the grade,” Zengerle recalls. “One of the videos showed exactly what to include in the presentation as well as 20

how to present it, and answered questions I had not had time to ask in class.” For Alexander Moyse (ENG’17), the videos’ principal advantage is their accessibility. “Unlike in most classes, I can watch the video as much as I want, whenever I want, until I understand all of it,” he says. EK301: ENERGIZING THE CLASSROOM WITH IPADS The two DLI pilot projects, EK127 and EK307, leverage pioneering work by faculty members in the Physics Department, including Professor Bennett Goldberg (Physics, ECE, BME), in peer-based learning and the use of studio space. The projects also apply lessons learned in ongoing, digital technology-enabled, classroom-flipping efforts by Fine in EK210, Assistant Professor Martin Steffen (BME, MED) in BE 209: Principles of Molecular Cell Biology and Biotechnology, and Lecturer Caleb Farny (ME) in EK301: Engineering Mechanics.

EK301: CALEB FARNY

As the College’s team of digital learning enthusiasts expands the use of blended learning technologies and techniques on campus, it also recognizes that one size does not fit all. With funding from a BU Redesigning the Undergraduate Learning Experience (RULE) grant, Farny has shown that one can dramatically boost active learning in the classroom without having to produce videos or redesign the physical space. Since the Spring 2012 semester edition of this required engineering course intended for sophomores, much of the lecture has been replaced by interactive problem-solving sessions and class discussions, all in a conventional lecture hall. Twice during each 110-minute class meeting, the instructor pre sents a 15-minute overview of a new concept and students work in groups of four on an example problem. Over 15 minutes, each group uses an iPad and stylus to show each step of its solution—including diagrams that depict the forces acting on a structure—and wirelessly uploads it to the file-sharing service Dropbox, where it may be accessed after class. Meanwhile, the instructor and three graduate teaching fellows and learning assistants circulate about the room to answer questions. When time is up, the instructor projects selected work on an overhead screen and invites a representative of the group to show how it solved the problem, using its iPad entries to highlight correct steps and common errors. Class discussions of student solutions are strictly focused on helping students to become better problem solvers, says Rebecca Rucks (ME’16), an EK301 learning assistant and former student of the course. “There’s no judgment when something is done incorrectly. It’s all seen as a learning experience.” Farny evaluated the new approach to EK301 the first semester it was introduced, offering one section in the old format and a second section in the new, but keeping all quizzes and exams the same. In a study that he and Associate Professor Sean Andersson (ME) presented to the American Society for Engineering Education in 2013 comparing mean quiz and exam scores, they found that students achieved significantly higher scores with the new format, regardless of grade point average. “This showed that our new, active learning approach worked well, and it’s been the format of the course ever since, unifying the course across multiple sections and improving test scores,” says Farny, who seniors voted Mechanical Engineering Professor of the Year for 2012.

Higher test scores stem from improved engagement with and understanding of the course material, observes Pantelis Gkaliamoutsas (ME/Economics’15), a learning assistant for EK301. “In a group format like the one in EK301, students are free to ask questions amongst themselves or call on a learning assistant or graduate teaching fellow for help,” he says. “This is important since many students feel more comfortable talking to the assistants rather than to the professor. I realized from my experience as a student in EK301 that I understood the problems we did in class more thoroughly, and was thus able to perform better on exams and quizzes.” Inspired by the success of EK301, Farny started flipping a seniorlevel course, ME 310: Instrumentation and Theory of Experiments, in the Fall 2014 semester, replacing ten hours of lecture with 18 course videos on the edX edge platform for home viewing and in-class measurement exercises in which student groups use plug-in sensors and portable data acquisition devices to conduct experiments and share their results onscreen. GOING DIGITAL, AMONG OTHER THINGS While digital learning has been a resounding success in courses that have tried it, the method is only beginning to gain traction at the College of Engineering. “At this point there is ample evidence that flipped classes with active learning environments work; the focus is now on how to get faculty to adopt these best practices,” says Attaway, noting that transforming a traditional lecture into an online course module— breaking it into bite-sized chunks, recording the video and hosting it on the edX platform—can take up to 20 hours. Simply letting go of the familiar lecture format can be challenging for some faculty. “Although my primary goal is to improve the learning experience for my students, my secondary goal is to be a resource for my colleagues so that I can help them transform their courses.” Toward that end, a College of Engineering faculty committee on digital learning initiatives is sharing best practices among faculty, redesigning courses (including ongoing efforts to flip EK127 and EK307), and purchasing new digital learning technologies, from electronic clickers that students can use to relay instant responses to questions posed during a lecture, to large, overhead projection screens to display solutions uploaded from student groups at active learning tables. As the College’s team of digital learning enthusiasts expands the use of blended learning technologies and techniques on campus, it also recognizes that one size does not fit all. “In my experience, students learn in myriad ways,” says Horenstein. “Some students thrive in the traditional lecture/homework environment, while others learn best in a hands-on setting, for example, when a small group works with a professor during office hours on specific problems and concepts. Still other students learn best in the laboratory, where they can transfer lecture/discussion concepts into the hands-on design of electric circuits that solve a problem or meet a desired specification. The hope is that digital learning will service all of these learning styles and more.” E N G I N E E R S P R I N G 2 0 1 5 W W W. B U . E D U / E N G

Dr. Brian Dunkin (BME’85) answers questions from the online audience during a multisite training program on advanced abdominal wall hernia repair. The program was broadcast from a studio in MITIE to an international audience.

All in a day’s work for Dunkin (BME’85), medical director of the Methodist Institute for Technology Innovation and Education (MITIESM), which, since its inception in 2007, has trained nearly 30,000 practicing health care professionals in the use of leading-edge surgical technology and techniques encompassing 24 specialties. Affiliated with Houston Methodist Hospital, MITIE seeks to transform how surgery is done internationally by spearheading and disseminating innovations that incorporate technologies such as robotics, MRI, CT-scans and computer-aided decision-making (CADM) into the operating room. The Institute has already significantly improved patient outcomes: its clinical CADM algorithm, which enables nurses to detect infections earlier in post-surgical patients, has reduced post-surgical infection mortality by 50 percent. Yet this is only half of what Dunkin does every day. He is also chief of Endoscopic Surgery at Houston Methodist Hospital, where he develops and clinically applies novel, minimally invasive, highly accurate surgical technologies and techniques to treat gastrointestinal diseases. Since joining Houston Methodist in 2007, he has introduced eight such technologies and techniques into clinical practice. Dunkin stresses that his engineering training is critical to his success. “My field is technology-intense, and my background in engineering has been invaluable, especially my senior project at BU,

where I learned how to define a problem, apply new concepts and move toward a solution as part of a team,” he says. In his clinical work and in courses he teaches at MITIE and as a professor of clinical surgery at the Weill Cornell Medical College in New York (the academic affiliate of Houston Methodist Hospital), Dunkin combines leading-edge expertise in flexible endoscopy—the use of a medical instrument with a flexible tube, light source and fiber-optic cameras to examine the inside of a hollow organ—and laparoscopic surgery, a surgical technique enabling operations within the abdomen to be performed through very tiny incisions, thereby reducing pain, blood loss and recovery time. For example, whereas open gall bladder surgery requires three to five days in the hospital and six to eight weeks recovery time, the laparoscopic procedure is done on an outpatient basis and requires only one week recovery time. One of the few surgeons with advanced knowledge and skills in both flexible endoscopy and laparoscopic surgery, Dunkin applies that expertise to surgically treat GI issues from acid reflux to kidney removal. His passion for biomedical engineering and surgery was sparked by two things—his older brother’s infectious enthusiasm for engineering, and an orthopedic surgeon’s dedicated and effective treatment of a shoulder injury Dunkin sustained in high school football. Seeking a course of study that would bridge E N G I N E E R S P R I N G 2 0 1 5 W W W. B U . E D U / E N G

engineering and medicine, Dunkin found his way to the College of Engineering. When he graduated cum laude in 1985, he was the only member of his BME senior class to attend medical school. It was while earning his medical degree at the University of Nevada that Dunkin began to connect the dots between his two current fields of expertise. “While training in general abdominal surgery, I saw that there was a revolution going on in minimally invasive surgery, from doing open surgery to laparoscopic surgery,” he recalls. “I felt if I wanted to be on the cutting edge of minimally invasive surgery, I’d have to combine laparoscopy with flexible endoscopy.” After receiving his MD in 1989, Dunkin completed a surgery residency at the George Washington University and fellowship in advanced laparoscopic surgery and flexible endoscopy at the Cleveland Clinic Foundation. He subsequently served as assistant professor of surgery at the University of Maryland and associate professor at the University of Miami, where he was director of the Center of Excellence for Laparoscopic and Minimally Invasive Surgery. Today Dunkin is widely recognized as a leader in minimally invasive gastrointestinal surgery. A fellow of the American College of Surgeons, he is president-elect of the Society of American Gastrointestinal and Endoscopic Surgeons, and serves on the editorial board of the Journal of Surgical Laparoscopy Endoscopy & Percutaneous Techniques. Active in several other medical organizations and publications, he is continually coming up with new ways to share his expertise. Dunkin’s latest innovation is a tele-mentoring program, in which he provides intensive training to surgeons at MITIE and subsequently uses telecommunications technology to guide them through actual surgeries back at their home hospitals.

BU COLLEGE OF ENGINEERING

The ultimate goal of the program, which currently focuses on laparoscopic colon surgery, is to make it easier for surgeons to learn and adopt new procedures. “No longer does a surgeon have to go to a short course to learn a new procedure and then return to his or her own operating room alone to try to work through the learning curve,” says Dunkin. “At MITIE, we developed a sophisticated hands-on training curriculum that uses at least four unique measurement tools to assess competence while allowing learners to rehearse in a simulated OR. After this hands-on experience in MITIE, we provide a telementoring infrastructure and method of communication back at the surgeons’ own hospitals that helps them move through their learning curve safely and efficiently.” The ultimate goal of the program, which currently focuses on laparoscopic colon surgery, is to make it easier for surgeons to learn and adopt new procedures. Just as he has done for many other MITIE training initiatives, Dunkin aims to leverage the multiplier effect of communications technology and expand this program to serve surgeons across the US and around the world.

SUSTAINABILITY: JUST ONE MORE THING YOU CAN GET AT WALMART.

ECE ALUM KATHLEEN MCLAUGHLIN TAKES ON THE GLOBAL CHALLENGE OF SUSTAINABILITY AT THE RETAIL GIANT. BY MARK DWORTZAN

BU COLLEGE OF ENGINEERING

he problem is daunting, to say the least. Somehow, the world will need to find a way to boost food supplies by 70 percent by 2050, when the global population is expected to reach 9.5 billion. Achieving that goal will require better distribution systems and farmers who can increase yields considerably while reducing water consumption and greenhouse gas (GHG) emissions. Enter Walmart, the world’s largest food retailer, serving 27 countries in 11,000 stores around the world. Working with its global network of suppliers and applying funding through the Walmart Foundation, its philanthropic arm, the company is taking a leading role in providing safe, affordable, accessible, healthy food for hundreds of millions of people. Walmart’s efforts include applying a “sustainability index” to suppliers to measure their progress in boosting yields while cutting water consumption and GHG emissions, and helping to train one million farmers. Through such initiatives, the company aims to ramp up the adoption of best practices in sustainable agriculture, thereby reducing the real cost of food—not only to the planet but also to the farmers and customers upon which its business depends. Leading the team behind this ambitious program is Kathleen McLaughlin (ECE’87), who serves as president of the Walmart Foundation and senior vice president of Walmart in charge of social and environmental initiatives, including energy efficiency, hunger relief and healthy eating, and women’s economic empowerment. “We’re taking a holistic approach in which we look at the problem as a system and partner with others to address it,” she says. “The problem-solving training I got in engineering, in systems thinking and feedback loops, is highly relevant in our efforts to rewire how the food system works.” On any given day, McLaughlin applies that training to several Walmart programs designed to simultaneously serve the needs of the business and the communities it serves—what she calls the “double bottom line.” A case in point is the Closed Loop Fund, a $100 million industry-funded program launched in 2014 with the help of the Walmart Foundation. The Fund provides zero- and low-interest loans to build recycling plants in municipalities across the US, with the ultimate goal of making recycling

available to all Americans. Cities and towns pay down the loans with sales of scrap metal and other recycled materials to local businesses (including Walmart suppliers), and savings from reduced landfill fees. McLaughlin routinely applies the double bottom line to sustainable agriculture, recycling and other social and environmental commitments by Walmart and the Walmart Foundation. Among the most ambitious are pledges to achieve zero waste to landfills in its operations by 2025, and to source an incremental $20 billion from female-owned companies for its US business through 2016. As McLaughlin pursues these commitments, she repeatedly asks herself, “How can we continue to improve what we’re doing so it’s sustainable for the business and its suppliers, employees and customers, and strengthens the communities in which we operate?” MAKING A DIFFERENCE Concerned with global environmental issues from a young age and inculcated with a passion for social justice at the Catholic elementary school she attended, McLaughlin has devoted her career— and much of her free time—to seeking and finding ways to make a difference. Taking after her father, an electrical engineer, she developed an early affinity for math and science, and felt naturally drawn to undergraduate programs in engineering. But she also maintained several other interests, from vocal music to international affairs, which she found ample opportunity to explore by pursuing her engineering studies at Boston University, where she was a Trustee Scholar. It was a University Professors Program course in the multinational politics of business—on how collaborations among businesses, governments and nonprofit organizations could thrive in an emerging era of globalization—that opened McLaughlin’s eyes as to how she might combine her passions for engineering and societal impact. “The course made me realize I had this passion for technology, but I wanted to pursue it in development, and I needed to learn more about economics and politics,” she recalls. When then-College of Engineering Dean Louis Padulo suggested that she might spend two years pursuing that knowledge at Oxford University as a Rhodes Scholar, she applied and was accepted. Upon graduating from BU summa cum laude, she earned a BA/MA degree in politics, philosophy and economics and a diploma in theology at Oxford. Initially setting her sights on a job at the World Bank, she instead spent the next two decades engaged in global commerce and development issues as a consultant for McKinsey and Company, a global management consulting firm, where she became a senior partner based in Toronto. IMPACTING THE GLOBE At McKinsey, she worked with multinational companies that were expanding their operations into the Americas, Europe and Asia, and spent one-third of her time as director of the firm’s Social Innovation Practice, partnering with corporate, philanthropic and nongovernmental organizations (NGOs) on programs to improve global health, nutrition and agricultural practices in developing countries. Among other things, she led efforts to spur more E N G I N E E R S P R I N G 2 0 1 5 W W W. B U . E D U / E N G

efficient government responses to HIV/AIDS in Africa, and helped government agencies and NGOs in Namibia strategize on how to reduce maternal mortality. In her spare time, she also served as director of the Toronto Community Foundation for 10 years, supporting Toronto NGO programs on poverty, hunger, housing and immigrant concerns. In 2013, she seized the opportunity when Walmart offered her the chance to apply her development expertise on a much broader scale, and moved with her husband Tim Costigan and their three children to northwest Arkansas, home to Walmart headquarters. “My experience at McKinsey allowed me to understand more about the private sector, and the fact that we live in a very interconnected world. The private sector has resources that are critical to addressing important global challenges,” says McLaughlin, now one year in at her Walmart post. “I believe we have limited time on the environmental and

social inequality fronts, and companies can collaborate with governments and NGOs to shift the system more rapidly.” Charged with effecting social and environmental change on a global scale and in a timely manner, McLaughlin works with a team of Walmart associates to design and execute an ambitious portfolio of Walmart and Walmart Foundation initiatives. A recent week on the job included reviews of philanthropic programs, meetings with Walmart suppliers, executives and partners, and a speaking engagement in Toronto on the role of companies in driving social and environmental change. At the same time, she oversaw multiple Walmart teams focused on energy efficiency, hunger, sustainable agriculture and other domains, and worked on improving sustainability of selected consumer product categories such as electronics and apparel. “Kathleen’s brought a level of knowledge about the issues, analytical thinking, energy and passion to the job of leading sustainability at Walmart that I’ve not seen before,” says Elizabeth Sturcken, managing director of the Environmental Defense Fund, which since 2008 has worked closely with Walmart to help the company develop its sustainability agenda. “You can’t fail to feel her passion and smarts when you talk to her about her work. If anyone can lead the big change that Walmart and the environment need, she can.” To tackle such complex challenges at Walmart and McKinsey, McLaughlin has turned, time and time again, to her grounding in engineering, which she calls “the perfect underpinning” for everything she’s done since graduating from BU. “It has served me very well in structuring ambiguous problems, taking them apart, dissecting them and solving them,” she says. “It’s such a fantastic foundation for pretty much anything you want to do in life.”

Pal wins Prestigious Metallurgy Award RECOGNIZED FOR CLEAN METALS PRODUCTION METHOD

he American Institute of Mining, Metallurgical and Petroleum Engineers (AIME) has named Professor Uday Pal (ME, MSE) the winner of its 2015 James Douglas Gold Medal Award, which recognizes outstanding achievement in nonferrous metallurgy, the extraction, purification, production and utilization of metals other than iron. Pal will receive the award at an AIME meeting in 2015. “It is very gratifying when recognition comes from one’s peer group in the same field,” said Pal, who has authored more than 200 publications and holds 23 patents on high-temperature chemical and electrochemical processes, including metals extraction and refining. “This award is special and humbling, considering the list of past awardees, many of whom are regarded as pillars of our field.” Pal is the inventor of solid oxide membrane (SOM) electrolysis,

BU COLLEGE OF ENGINEERING

an inexpensive, energy-efficient, environmentally friendly, one-step method that he has developed over the past 15 years to separate pure metals from their oxides. SOM electrolysis continuously feeds metal oxide into a molten salt bath, where electricity splits it into metal and oxygen gas in separate chambers. Conventional metals production technologies employ a lot of carbon-based energy sources to reduce oxides, and generate significant amounts of pollutants, carbon dioxide and other greenhouse gases. SOM electrolysis promises to substantially decrease energy consumption and eliminate carbon and other environmentally harmful emissions associated with reducing oxides to metals, all for lower cost. So far Pal has developed and applied his patented SOM electrolysis technology to produce magnesium, titanium, silicon, aluminum and other energy-intensive metals from their oxides. Infinium, a Natick-based company spun off from Pal’s lab, is now working toward a scale-up of this technology. “Uday is an outstanding practitioner of chemical metallurgy and materials science, bridging the gap between fundamental understanding and direct industrial relevance,” said Adam C. Powell, IV, CTO and co-founder of Infinium. “He has been a pioneer in the new sub-discipline of green metallurgy and materials, and has launched the careers of dozens of engineering graduate students, including my own.”

DAVID MOUNTAIN

THOMAS KINCAID

Professor David C. Mountain (BME), 68, died on November 5 in Newburyport, Massachusetts. An internationally recognized professor of biomedical engineering at Boston University for 35 years, Mountain pursued research on auditory function and underwater acoustics and was a co-founder of Biomimetic Systems, Inc., a Cambridge-based startup advancing acoustic sensors for medical, military and other applications. In 2002 he was inducted as a Fellow of the American Institute for Medical and Biological Engineering. As a principal investigator at the Auditory Biophysics and Simulation Laboratory and a key member of the Hearing Research Center, Mountain pursued studies that combined engineering and physiological techniques to model and improve understanding of the hearing process. Mountain took a leading role in the design and evolution of the BME department’s undergraduate and graduate curricula, and served for many years as a member of the University’s Faculty Council, representing the College of Engineering.

Emeritus Professor Thomas G. Kincaid, a longtime faculty member and former chair of the ECE Department, died on January 18 at the age of 77. He joined the Boston University faculty in 1983, served as ECE chair from 1983 to 1994 and retired in 2006. Kincaid’s research focused on signal and image processing, photonics, dynamic neural networks and nondestructive testing. He taught courses in engineering and in logic design, signals and systems, and advised graduate students pursuing degrees in electrical engineering. Previously, he worked as a researcher for General Electric. A member of the IEEE, he received his PhD from MIT in 1965. As ECE chair, Kincaid increased the size of the department by more than 50 percent, hiring faculty who included three future ECE chairs— ECE Professors Bahaa Saleh (Emeritus), David Castañón (SE) and W. Clem Karl (BME, SE). He also increased the size of the graduate program and focused it on doctoral education.

Anne Everett Wojtkowski, First BU Female Engineering Student anne everett wojtkowski (cit’56), the first female engineering student at Boston University, where she studied aeronautical engineering, died in October at the age of 79 in Pittsfield, Massachusetts. She also served as the first female mayor of Pittsfield from 1988 to 1992, helped to establish one of the first early childhood education programs in the US, and advocated for equal pay for female faculty members during a 35-year career as a professor of mathematics and engineering at Berkshire Community College. 36

Jimmy Trinh, BS,

1988 Hudson, Massachusetts

Jimmy’s happiest day was when his son Julian received his acceptance letter from the College of Engineering. On a recent campus tour, he enjoyed strolling down Commonwealth Avenue and chasing the Green Line trolley. Anita Sengupta, BS,

1998 Pasadena, California

A senior systems engineer at the Jet Propulsion Laboratory, Anita is the project manager of NASA’s Cold Atom Laboratory (CAL) mission team, which has produced an ultra-low temperature state of matter known as a Bose-Einstein condensate in a prototype for an instrument that will debut on the International Space Station in late 2016. CAL will enable potentially groundbreaking fundamental physics research in temperatures colder than any found on Earth. Kyle Allison, PhD,

2013 New York, New York

Kyle received a National Institutes of Health Director’s Early Independence Award based largely on research he conducted as a PhD student in Biomedical Engineering at BU. One of 17 issued nationwide, the award provides up to $250,000 per year for five years to enable exceptional early career scientists to skip traditional postdoctoral training and move rapidly into independent research positions at US institutions. Currently a postdoctoral fellow at Columbia University, Allison developed an innovative method to eradicate “persisters,” dormant bacterial cells believed to be responsible for perpetuating chronic bacterial infections.

While earning his PhD in Biomedical Engineering at Boston University, Kyle Allison (BME, PHD’13) developed a new approach for eradicating persistent bacterial infections.

INSPIRING SOCIETAL ENGINEERS The College of Engineering’s Inspiration Ambassadors are introducing young people to the impact engineering can have on society and showing them pathways to exciting careers in the field. Professionally trained through the College’s Technology Innovation Scholars Program, these BU engineering under-

graduates have delivered presentations and facilitated design challenges for more than 9,500 middle and high school students in 19 states. Through your donation to the Engineering Annual Fund, you can help meet the growing demand for more Inspiration Ambassadors and support other transformative undergraduate programs.

Inspiring Young People to be Societal Engineers “Last year I visited middle and high school students in Boston and in my hometown, guiding them to design their own computer games and wind turbines. It was a great personal joy to inspire these young people to consider engineering, and to share with them how they can change lives by aspiring to become Societal Engineers.” —Charina Ortega (BME’16) Impacting the Community “I was amazed at the incredible capabilities of the Boston high school students that I worked with on the robotics team, many of whom were homeless, living apart from their parents or facing other difficult challenges. In addition to coaching them, we encouraged them to apply for the BU Menino Scholarships and Community Scholarships—and two of last year’s high school seniors received these scholarships and admission to BU.” —Jennifer Larbi (BME’15) Meeting Emerging Workforce Needs “This program taught me many extremely useful skills for the workplace, including mentoring, which is highly valued at GE. As an Inspiration Ambassador and a leader on several FIRST Robotics teams, I learned how to adapt to each individual’s skill level, interest and aptitude. I was able to share my passion while teaching students how to mentor each other and organize in cross- functional teams.” —Oliver Kempf (Aero’12, ME’16), Performance Engineer, GE Aviation You can help shape future alumni into well-rounded Societal Engineers who have a lasting impact on the world by giving to the Engineering Annual Fund today.

Ari Trachtenberg PHD, UNIVERSITY OF ILLINOIS, URBANA-CHAMPAIGN PROFESSOR, DEPARTMENT OF ELECTRICAL ENGINEERING & COMPUTER SCIENCE

Today’s smartphones are an extension of our personage. Like an extra limb, they follow us to our most intimate environments, wirelessly exposing our every action to the world through a wide variety of onboard sensors. People love their games and rely on these devices to contact friends and access bank accounts, but do they really know what is going on inside those small frames? Our work focuses on identifying and exposing the threats these ubiquitous communication devices

pose at all layers of abstraction— from hardware to communication systems, sensors, operating systems and applications—and developing defenses primarily against remote exploitation. Boston University engineering students are the lifeblood of this research. It is their passion and creativity, infused with the engineering culture of persistence, that leads to the discoveries that make the research process worthwhile. An essential catalyst for this creativity is BU’s environment of breaking down antiquated boundaries, be they between bureaucracies, disciplines or people at different stages of their lives. This is especially important for cybersecurity research, in which progress is intrinsically tied to a broad range of technical and nontechnical understanding.
