from the dean

The UCLA Henry Samueli School of Engineering and Applied Science is conducting vital research that will protect our civil and electronic infrastructure, and even more importantly, will play critical roles in saving lives. Destructive earthquakes in Japan, Chile, Haiti and New Zealand over the past three years have been sobering reminders that we live on a seismically active planet. And unquestionably this threat exists in California. Many of our Civil and Environmental Engineering faculty are on the ground floor, leading efforts to dramatically improve our infrastructure resiliency, including John Wallace, Jonathan Stewart, Scott Brandenberg, and Ertugrul Taciroglu. In this issue, we ask them to share some of the significant work they are doing. Further, a more subtle, but just as real a threat, can be a malicious electronic attack. Our faculty has some of the world’s very best minds working to prevent and intercept these threats. This issue features Q&A’s with computer science professor Rafail Ostrovsky and electrical engineering professor John Villasenor, experts on cyber security and hardware security respectively. This edition of UCLA Engineer also features a profile on our 2011 Alumnus of the Year, Ernst Volgenau PhD ’66, who began his business in the basement of his home three decades ago and ultimately grew it into a $1.7 billion global empire. Our career column features another successful alumnus, Shioupyn Shen PhD ’91, co-founder of CloudMosa Inc., who talks about the challenges and excitement of starting your own company. In addition, this issue highlights the impact of the important work our engineering students are making. Learn about the successes of our new student mentorship program and about the difference our graduate students are making at several K-12 schools. Finally, this issue includes new research of mouse genomes and cell-penetrating peptides; a story on a new faculty startup fostered by our Institute for Technology Advancement; exciting new developments within our Boelter Society; and our new endowed faculty chairs. I invite you to enjoy another enlightening issue of UCLA Engineer. Sincerely,

Developing a complete map of

mouse genetic variation Wileen Wong Kromhout

or decades, laboratory mice have been widely used in research aimed at understanding which genes are involved in various illnesses. But actual variations in past gene sequences of mice were unknown. While researchers were able to determine that a variant affecting disease was in a certain region, they couldn’t pinpoint the exact set of variants in that region. Now, in new research recently published in the journal Nature, an international team of investigators that included UCLA researchers, reports that it has sequenced the complete genomes of 17 strains of mice, including the most frequently used laboratory strains. The massive genetic catalog will provide scientists with unparalleled data for studying both how genetic variation affects phenotype and how mice evolved. UCLA Engineering researchers played a key role in the study, using UCLA-developed technology to help sequence a nearly complete map of mouse genetic variation. Cataloging the full set of variants is a first step in identifying the actual variants affecting disease. “The actual number of variants discovered is important because this gives the complete picture of how much variation exists in these mouse strains,” said Eleazar Eskin, an associate professor of computer science who develops

techniques for solving computational problems that arise in the study of the genetic basis of disease. The new study was led by groups from the Wellcome Trust Sanger Institute and the Wellcome Trust Centre for Human Genetics in Oxford. Previous technology used in the genetic sequencing would, in some cases, make ambiguous predictions, and the locations of these ambiguities resulted in missing entries in the catalog of genetic variation in mice. “Our role in the collaboration was to apply a technique that we developed a couple years ago for predicting variants where the sequencer failed to make a prediction,” said Eskin, who holds a joint appointment in the department of human genetics at the David Geffen School of Medicine at UCLA. With the full set of genetic information, researchers can now accurately predict the phylogeny — similar in concept to the family tree — of how the various mouse strains are related. The new study confirms that mice have a complex evolutionary history. The complete release is available online at: www.engineer.ucla.edu/mouse-genetic-variation

cell-penetrating peptides

for drug delivery act like a SwiSS army knife Wileen Wong Kromhout

ell-penetrating peptides, such as the HIV TAT peptide, are able to enter cells using a number of mechanisms, from direct entry to endocytosis, a process by which cells internalize molecules by engulfing them. Further, these cell-penetrating peptides, or CPPs, can facilitate the cellular transfer of various molecular cargoes, from small chemical molecules to nano-sized particles and large fragments of DNA. Because of this ability, CPPs hold great potential as in vitro and in vivo delivery vehicles for use in research and for the targeted delivery of therapeutics to individual cells. But exactly how cell-penetrating peptides — and particularly the HIV TAT peptide — accomplish these tasks has so far been a mystery. “The HIV TAT peptide is special. People discovered that one can attach almost anything to this peptide and it could drag it across the cell,” said Gerard Wong, a professor of bioengineering and of chemistry and biochemistry, and a member of the California NanoSystems Institute at UCLA. “So there are obvious beneficial drug-delivery and biotechnology applications.” In a new study published in the Proceedings of the National Academy of Science, UCLA Engineering researchers identify how HIV TAT peptides can have multiple interactions with the cell membrane, the actin cytoskeleton and specific cell-surface receptors to produce multiple pathways of translocation under different conditions. Moreover, because the researchers now understand how cell-penetrating peptides work, they say it is possible to formulate a general recipe for reprogramming normal peptides into CPPs. “Prior to this, people didn’t really know how it all worked, but we found that the HIV TAT peptide is really kind of like a Swiss Army Knife molecule, in that it can interact very strongly with membranes, as well as with the cytoskeletons of cells,” said Wong. “The second part wasn’t well appreciated by the field.”

In addition to the membrane activity, researchers discovered that the HIV TAT peptide also creates its own binding site out of the membrane. This means the peptide can actually go through the membrane and induce the cytoskeleton directly to have an endocytotic event. Researchers also noticed that small cargoes can be transferred directly, while cargoes larger than a few nanometers needed to be anchored to the membrane by the TAT peptide. The study was funded by the National Science Foundation and the National Institutes of Health.

Schematic representation shows that HIV TAT (blue) can permeate membranes and interact with the cytoskeleton (green).

InfrasTrucTure resIlIency: Making Buildings safer froM destructive earthquakes Matthew Chin

he edges of tectonic plate boundaries are very seismically active regions. This includes California as well as other parts of the globe, such as the Pacific Rim, known as the Ring of Fire, and Turkey. Recent powerful earthquakes in Chile in 2010 and in Japan in 2011 were among the largest ever recorded. And another large earthquake centered close to the modern city of Christchurch, New Zealand, caused much extensive damage. UCLA Civil and Environmental Engineering faculty are closely examining some of the damage from the quakes mentioned and working to make buildings and infrastructure safer in the likely event of a large earthquake in the U.S. and in particular California. Below is just a glimpse into some of that work.

professor john wallace, directs a large lab at the base of Boelter Hall that simulates earthquake shaking on concrete structures. He’s also the principal investigator at NEES@UCLA, the mobile field lab of the National Science Foundation’s George E. Brown, Jr. Network for Earthquake Engineering Simulation. Shortly after an 8.8 magnitude earthquake, one of the largest ever measured, struck off the coast of Chile in February 2010, Wallace led a field team to the capital city of Santiago to set up monitoring systems John Wallace at E-Defense, with on several buildings to study how Alberto Salamanca, assistant they responded to the quake and development engineer, and Zeynep Tuna, Ph.D. student.

strong aftershocks. Chile has concrete building codes very similar to those in the U.S. and gathering data following large ground motions could lead to insight on how California buildings would fare in a very large earthquake. “The study of buildings in Chile has helped us identify a handful of very important issues related to building safety that need to be addressed in our codes, issues that we would not have identified if not jolted by this quake,” Wallace said. The strong shaking caused some buildings to be permanently tilted from their foundations. One issue that may have contributed to that was the performance of thinner concrete walls in tall buildings. This field-collected data has been supplemented by lab tests at the University of Tokyo’s Earthquake Research Institute and Earthquake-Defense facility, with the largest shaking table in the world, where Wallace spent his sabbatical in the fall of 2010. While the test results have not been completely reviewed, preliminary results suggest the issues identified in Chile do need to be addressed in the U.S., as well as Japan. “The goals now are to implement code changes in the U.S. that address these identified problems and to educate practicing engineers about these changes,” he said. Wallace is leading efforts this year within the American Concrete Institute to update code changes on reinforced concrete buildings to reflect what was learned both on site in Chile and in Japan. This fall, he will also chair a special session at the upcoming World Conference on Earthquake Engineering related to these efforts.

Our computer system infrastructure can be vulnerable to malicious attacks. UCLA Engineering has some of the world’s best experts working to protect these critical resources. Below are interviews with two of those experts. John Villasenor, professor of electrical engineering. Tell me a little about your current research in the area of hardware security. What has been your focus? Why? Villasenor: While everyone has heard of threats such as software viruses, there is much less awareness of the risk that the chips at the core of today’s electronic devices and systems could themselves be compromised from the moment they are designed. Malicious circuitry can be built in to a chip and lie hidden for months or years until it is activated. At that point, there are many different types of hardware attacks that could be launched. For example, the attack could cause the chip, and therefore the device that contains it, to stop functioning. Another possibility is that data passing through the chip could be surreptitiously leaked. Given the vital importance of electronics systems for communications, national defense, the financial markets, the power grid and other aspects of our infrastructure, it is extremely important to ensure that the chips at the core of these systems have not been compromised.

Why would you say hardware security today is just as important as software security? For typical consumers, software security is more important because they can take steps to minimize the risk of having a software security problem. For example, they can use up-to-date antivirus software and exercise care regarding the types of personal information they provide when using electronic devices. By contrast, hardware security really needs to be addressed earlier in the supply chain — by the companies that are involved in designing chips, and the companies that purchase those chips to place in their products. For those companies, hardware security is an important, and often underappreciated, concern.

How has the advancement/change in technology affected this issue? First, chips are tested before they are inserted into products, but today’s chips are too complex to test exhaustively. As a result, an attack can remain hidden during the testing process. Second, the globalization of chip design has led to an enormous increase in the number of people who contribute to — and so have access to — the circuit designs that will eventually end up in a chip. These designs often involve outsourcing arrangements that can span multiple companies and continents, and involve many layers of suppliers. If even a tiny percentage of the people involved in designing chips act maliciously, that’s still an enormous concern.

In the media recently, you’ve been asked to address a few areas involving national security. What may be some issues that people aren’t looking at yet but in your opinion should? There are certainly people in the Department of Defense (DOD) who are well aware of the hardware security risk. For example the Defense Advanced Research Projects Agency, which is the main research arm of the DoD, has been funding important work in this area for a number of years. But the overwhelming majority of the electronics, including in DoD systems, involves the commercial supply chain. In most segments of the commercial world, hardware security isn’t really on the radar in any meaningful way. I think it is very important to be proactive, not reactive, regarding this vulnerability. To find out more about John Villasenor’s research in hardware security, and to read his essays on technology policy, visit his Web site at: http://ipl.johnvillasenor.com/

Rafail Ostrovsky, professor of computer science and mathematics and director of the center for Information & computation Security. Can you describe some major current issues in cyber security today? Ostrovsky: Our society gets more mobile and more interconnected every day. For example, most of our data either already leaves or soon will migrate to the clouds, owned by big corporations; our mobile data, including personal preferences regarding shopping, travel, and online searches, are mined by companies for targeted advertisements. This ubiquitous connectivity is both helpful and harmful. It is helpful in communicating with our friends, yet it is harmful as individual privacy often becomes compromised. The biggest challenge of cryptography is to allow individual privacy to be maintained without hindering services and conveniences that the Internet and mobile platforms and cloud-based computing has to offer. The idea is instead of limiting what the big corporations can touch, to allow processing and manipulation of encrypted data in a way that carefully controls the information flow, while at the same time protecting individual privacy.

With regards to those issues, can you describe some of the research you’re leading that addresses those issues? My group’s research focuses on developing new technologies for allowing willing participants to utilize benefits of the Internet and mobile platforms without violating individual privacy. What makes the research especially fun is trying to formalize in a rigorous mathematical sense what this means and how to prevent privacy breaches without limiting functionality and usefulness of the systems at hand. It is also important to be able to prove that even if some of the participants are malicious, and deviate from the protocol in an arbitrary, devious way, they cannot

sabotage the system. While important gains on this front have been made, many outstanding questions remain, especially when security and privacy guarantees must hold in a dynamic and changing environment, such as the Internet.

Where will we be 10 years down the road in regards to cyber security? I see cyber security being far more pervasive ten years from now. Most of our devices, including buildings, cars, and home appliances will be wirelessly interconnected and will attempt to be more “helpful” to their owners. That will make our lives easier on the one hand, and more dangerous on the other. Imagine, for example, if you can switch on your stove, your microwave and your air-conditioner remotely through a hand-held device, or just a few hand gestures in front of your iPad. It sounds very appealing for individual citizens, but also could make it much easier for criminals to cause damage through identity theft or for terrorists and rogue states to cause massive political and economic damage through cyber-attacks that will be coupled with physical systems and control devices. This is the challenge of cyber security: to allow ever increasing ease of use and convenience for individual citizens and businesses, while at the same time protecting individual privacy and national cyber security. It’s an exciting time for those of us working in this field, since both the good guys and the bad guys continue to develop ever more sophisticated attacks and defense systems — we must be ahead of the bad guys at all times. The full text of the Q&A with Professor Ostrovsky, including his thoughts on cloud computing issues, is available at: www.engineer.ucla.edu/cybersecurity-Q-and-A To find out more about Professor Ostrovksy’s research in cryptography and other areas of computer science, visit his Web site at: www.cs.ucla.edu/~rafail/

Billion-Dollar Business Allowed Founder to ContInue to Serve hIS Country Wileen Wong Kromhout

t’s hard to believe, SRA International, Inc., a government IT services and system-integration company, with revenue of $1.7 billion and nearly 7,000 employees, began in the basement of Ernst Volgenau’s home in Reston, Virginia in 1978. To comprehend the success of the company, one only needs to understand the man behind it. Volgenau PhD ’66, President and CEO of SRA International for almost 30 years and currently Chairman of the Board, came from humble beginnings. Growing up on a small farm in western New York, he learned the value of dedication and hard work and credits his parents and siblings for setting high expectations and being great role models. Volgenau dreamed of becoming an astronaut and as a young man was offered a scholarship to MIT to study nuclear engineering. At the same time, he was also selected for appointment to the U.S. Naval Academy at Annapolis. Volgenau choose to serve his country. “It was a tough choice, but I decided on the Naval Academy, and spent four years there,” remembered Volgenau. “Later I transferred to the Air Force because of poor eye sight. In those days, your eyes had to be perfect and the Navy would have given me restricted commission. The Air Force, however, allowed me to join a combat missile squadron without that limitation and also promised me graduate school.” During his early years in the Air Force, Volgenau was assigned to Los Angeles with his young wife, Sara. He had a masters degree and was working in the Air Force space program in the early 1960s at a time when there were many space initiatives – satellites and other space vehicles. Volgenau also began teaching graduate courses at UCLA Extension, where a professor encouraged him to obtain a Ph.D. in engineering.

“UCLA was all work and no play,” said Volgenau. “In those days, I had to finish my exams and dissertation in a limited amount of time. My wife, Sara, and I lived in Woodland Hills, and we had two young children. We were very busy. But my whole thought process was changed as a result of my graduate studies at UCLA.” Volgenau ultimately spent two decades in the Air Force, where he put his engineering degrees to work on space boosters and satellites. He then taught and attended the Air Force astronaut school. Later he was an analyst in a Pentagon office informally known as “the Whiz Kids.” Eventually he managed computer development projects at the Air Force Logistics Command. Just before starting SRA International, Volgenau was Director of Inspection and Enforcement for the U.S. Nuclear Regulatory Commission. He managed 700 engineers and physicists who inspected all commercial nuclear power plants in operation and under construction. For ten years, he taught evening classes in engineering, operations research, and computer systems in graduate schools at UCLA, Wright State University, American University, and George Washington University. “I taught these classes in order to keep academically proficient in areas related to my work,” said Volgenau. “When I worked in aerospace programs, I taught control systems. When I worked in computers, I taught computer design and management. One of my Ph.D. fields was in computer design. I was really interested in that field and wanted to start a firm that would specialize in the application of computers. When I started SRA International, there were not many companies like it.” Volgenau believes wholeheartedly in serving society. The values he holds most dear have been embedded deeply in SRA, which has the ethic “honesty and service.”

ucla was all work and no “play. In those days, I had to finish my exams and dissertation in a limited amount of time. My wife, Sara, and I lived in Woodland Hills, and we had two young children. We were very busy. But my whole thought process was changed as a result of my graduate studies at ucla.”

SRA was named by Fortune magazine as one of the 100 best companies to work for in America for ten years in a row. “Our ethic of honesty and service has four components,” said Volgenau. “First, we are always honest. Second, we do good work for our customers. Third, we care for one another, and fourth we serve society in other ways, for example through charitable contributions of time and money.” When asked to provide some words of wisdom on starting a company in today’s economic environment, Volgenau said, “Be prepared to work very hard and sacrifice a lot. Plan ahead… don’t just open your doors. Hire really good people, give them plenty of responsibility and insist on working together as a team.” “Most important of all,” Volgenau continued, “is to have high ethical standards. Really good people want to be part of something special. Being successful financially

Ernst Volgenau

is essential, but a company should also stand for something.” Today, Volgenau credits his wife, Sara, for helping him achieve much of his success by being such a strong partner at home. He enjoys spending time with his family of three wonderful daughters, three great sons-in-law, and nine promising grandchildren. He is proud of his service in the military and proud to be an American.

New MeNtorship progrAM Helps Students Ease into University Life Matthew Chin

ll UCLA Engineering students are admitted after having proven themselves by earning top grades in the classroom. However, navigating university life is more than just classes and labs, homework and projects. It’s managing a busy academic schedule, while also fitting in those extracurricular activities that complete the college experience. Along with all that comes choosing the path that best fits their own interests and future career goals. Getting through the first two years can be tough for all students, and even overwhelming for some. To ease this important transition to university life, UCLA Engineering put into place a new program this year that matches every entering freshman and new transfer student with an engineering upperclassman trained to be a mentor. “There’s always been so much experience that upperclassmen could offer, but so inaccessible in a way, unless you got involved with a club,” said electrical engineering senior Tammy Chang, who led a pilot mentor effort in her major last year, and is now the student lead for the school-wide effort. Student organizations offer some form of tutoring and mentoring along with opportunities to work on club projects. However new students had to actively seek out those groups. Now, thanks to the Office of Academic and Student Affairs and the SEASnet computing facility, peer mentoring has been made easily accessible to those

students and the process has been streamlined through CourseWeb, the electronic home for an engineering student’s academic life. “You always have people who are coming in who need help, and you always have people who have been here for a while who can help, and possibly who want to help,” Chang said. “And all we’re doing this year is providing a connection between those two groups.” Instead of needing to be active with a specific organization, now all incoming students automatically know there’s a mentorship program even before they begin their fall quarter. In this year’s program, mentees were paired with mentors from their own major. Students who are undeclared were matched with mentors through studentrun societies like Society of Women Engineers (SWE); the engineering honor society, Tau Beta Pi; and the Engineering Society of UCLA (ESUC). Throughout the fall quarter each group held its own events that included info-sessions with academic counselors. “We received such an overwhelmingly positive response from mentees and mentors who were in the electrical engineering pilot program last year, that we decided to implement this school-wide,” said Richard D. Wesel, associate dean of academic and student affairs. “We have great students who want to be mentors and incoming students who are really helped by their peers. This new effort simply makes it much easier for everyone to connect.”

The new student mentorship program also complements other advising opportunities already in place at the school, including academic counseling, as well as the faculty mentorship program, where professors provide advice each quarter to assigned mentees on topics ranging from undergraduate research to graduate schools and working in industry.

Hall, Engineering IV and Engineering V. The places they found were beneficial to new students getting to know the school, such as the undergraduate lounge where tutoring is available. Other events have included class scheduling and resume building workshops. Mentors with SWE, Tau Beta Pi and ESUC also held an introductory session on different

We have great students who want to be mentors and incoming students who are really helped by their peers. This new effort simply makes it much easier for everyone to connect.”— r ic h a r d d . w esel For electrical engineering freshman Emily Im, the student mentorship program has helped boost her confidence. Im met with her mentor, and attended an informational “pathways” workshop on the different course pathways offered in electrical engineering. Now she says she is much more positive about the next few years. “I knew that majoring in engineering was going to be difficult, but I didn’t have any background knowledge and I felt that I was just diving into the unknown,” Im said. “I know more of what to expect in the future and just knowing that someone is willing to answer any of my questions is comforting as well.” For their first event, to help become more acquainted, several of the mentor groups held scavenger hunts around campus with their mentees. However the one held by electrical engineering mentors got rained out. But as good problem-solving engineers would do, the mentors devised an alternate program for that day. They changed the scavenger hunt to an exercise on how best to navigate the campus when it rains. Mentees had to use binary code to decipher clues that would take them around Boelter

majors for undeclared students. In addition, mentors in Materials Science and Engineering held a gingerbread house workshop, complete with a load-bearing competition. Events planned for winter quarter focused on potential internships and other summer experiences. Chang, who empathizes with many of the new students as she herself transferred into engineering from statistics, suggested that this year the student mentorship program has reached about 40 to 60 percent of its potential. “The way we can continue to improve this program is by making it known to students that this is something meaningful,” Chang said.

graduate students

bring clean energy workshops to high school classrooms Matthew Chin

nergy takes work. Hard work, and a lot of it, in fact. That’s the starting point in the EnGen Roadshow, a presentation to Los Angeles-area high school science classes created by several UCLA graduate students in engineering and the sciences. Through the use of several demonstrations, including a hand-crank generator, a steam engine, photovoltaic cell, and even a mini-hydroelectric generator, the graduate students begin a discussion on where different sources

Clean Green IGERT Fellows of energy come from; the technologies and efficiency of converting them to a more useful form of electricity; then finally, the environmental impacts that they each have. The students are all fellows in UCLA’s Clean Green Integrative (CGI) Graduate Education Research Traineeship (IGERT), a National Science Foundationfunded program that aims to develop leaders in environmental energy through integrated research and

coursework in the science, business and policies of clean technology. The interdisciplinary program includes engineers, as well as chemists, economists, statisticians and public policy students. Designing a program to educate K-12 students on clean energy is part of the program’s mission. Additional funding from the American Recovery and Reinvestment Act requires a program with impact on the future of green technology in greater Los Angeles. The Clean Green IGERT fellows decided to focus their efforts at the high school level. “Many of us felt that we were not exposed to the fundamentals of clean energy in high school and we hoped to make students aware of energy issues as they are beginning to seriously contemplate their future career paths,” said Clean Green IGERT fellow Leland Smith, a materials science and engineering graduate student. “We hoped to show the relevance of math and science education on real world problems.” So far, the group has presented to three high schools, including Bell Gardens High; Alexander Hamilton High in Los Angeles, and Redondo Union High in Redondo Beach. At Hamilton, the fellows gave their talks in teacher Dina A. Kraemer’s Advanced Placement environmental sciences classes. Her course is geared to helping students discover strong connections between science, technology and public policy issues. Clean Green IGERT fellow Joshua Shapiro demonstrates solar thermal energy. “I cannot emphasize enough the power of 20something grad students presenting,” Kraemer said. “The kids are mesmerized by individuals that are close in age and see their future in them.”

Leland Smith at Hamilton High in Los Angeles

At the front of the classroom, the fellows had high school students try a hand-crank generator or lifting a bucket of water overhead for hydroelectric power, both of which connect to an LED that lights up when it receives electricity. But for the students, turning the crank or lifting that bucket starts to become difficult after a minute. And that’s the exactly what the UCLA graduate students want, as it shows just how much work it takes to convert even a little bit of potential energy into the more useful form of electricity. Following the demonstrations, the Clean Green IGERT fellows discuss the many types of energy sources, as well as their effects on the environment. Many of the high schoolers’ questions ask where clean and renewable energy currently stands and when it will become more readily available. “Our energy consumption comes at a price, and it is up to us as a society to determine what that price should be,” said Shapiro, an electrical engineering graduate student. “We believe that by educating about where electricity comes from and the real costs associated with producing electricity, people will become more prudent consumers of energy.” While the lessons are intended to benefit the students they present to, it’s been a positive learning experience for them as well. “As grad students, we spend a lot of time thinking about the fine details of energy technology and talking with people who have a deep knowledge of the problem,” Smith said. “It becomes easy to take for granted that people have a high level of understanding of these issues. It is entirely different to speak with people who know high school science, but not much more about clean energy. As tomorrow’s leaders in clean energy, this is an invaluable

experience for the Clean Green IGERT fellows.” In addition to the outreach component, the Clean Green IGERT faculty members have developed two graduate clean energy courses designed to spur discussion and collaboration between the fellows. The topics include policy, economics, energy harvesting, storage, and conservation. The classes are cross-listed and available to all graduate students. “One of the premises of our program is to assemble a broad-range of disciplines all involved in clean energy,” said electrical engineering professor Diana Huffaker, director of the Clean Green IGERT and a member of the California NanoSystems Institute. “It is at the interface of standard disciplines that innovation can come about.” A short video of the EnGen Roadshow’s demonstrations is available online at: www.engineer.ucla.edu/clean-energy-workshops

Building the SmaRt gRid of the futuRe: ucla teams with Korea’s energy Research institute Wileen Wong Kromhout

CLA Engineering has entered into a 10-year partnership with the government-supported Korea Institute of Energy Research (KIER) in South Korea to collaborate on smart-grid research and the development of new technologies with the aim of creating a robust smart grid on an international level. As part of that effort, the Smart Grid Energy Research Center (SMERC) is using the campus — in particular, Boelter Hall and the Engineering IV and V buildings — as an experimental lab to observe how wireless sensing and control systems can help create the smart grid. The team, led by mechanical and aerospace engineering professor Rajit Gadh, the center’s director, is retrofitting these structures with cutting-edge sensors and smart meters that can, for example, gauge and adjust the amount of power needed in a room at a particular time

Jung-in Choi, a Korean professor, who has also been working on smart grid research since 2005, introduced KIER to Gadh. Choi came to UCLA on sabbatical from Kyungwon University and learned about Gadh’s research through several news articles.

“I think SMERC is one of the most active research institutes in the smart-grid field today,” he said. “In particular I have been most interested in the open architecture platform for the smart grid — Dr. Gadh’s WINSmartGridTM in particular. KIER needs an open architecture platform technology, and I thought a partnership between KIER and SMERC would be beneficial for both.” The UCLA WINSmartGridTM (Wireless Internet Smart Grid) is a network platform that allows electrically operated machines and appliances such as plug-in electric vehicles, washers, dryers and air conditioners to be wirelessly monitored, connected and controlled through a wireless communications framework. Control signals can subsequently be sent via the WINSmartGridTM network, which in turn can dynamically control various appliances in real time. Gadh envisions electric vehicles guzzling energy into their batteries overnight, when power is cheap, and then dispensing it back into homes and offices during the day, when electricity demand is at its highest. In UCLA’s Parking Structure 9, located next to the retrofitted engineering buildings, Gadh has installed two EV charging stations with devices that collect and wirelessly transmit data about electricity usage back to his lab. As part of Korea’s effort to grow its technology and knowledge in the area of green and renewable energy, the country in 2009 launched a national smart-grid demonstration project with the construction of a smart-grid testbed on Jeju Island. The test bed will become the world’s largest smart grid community, allowing the testing of the most advanced technologies.

professor’s startup begins Full-Scale Operations Wileen Wong Kromhout

ydogan Ozcan, associate professor of electrical engineering and bioengineering, has garnered a great deal of media attention and professional recognition in recent years for his work on lensless computational microscopy. Most recently, The Scientist, a magazine focusing on the life sciences, research and technology, declared Ozcan’s microscopy platform the top innovation of 2011, claiming the No. 1 spot in their Top 10 list. His group’s computational microscopy technology, with the help of UCLA Engineering’s Institute for Technology Advancement (ITA), has now led to a spinoff called Holomic LLC. A few months ago, Holomic officially announced its founding and start of full-scale operations in Los Angeles, after receiving $2.5 million in seed funding from a strategic investor as well as an NIH Small Business Innovation Research (SBIR) grant of $383,000. “Holomic LLC’s mission is to commercialize technologies created by my research group at UCLA and expand the range and number of microscopy applications to benefit communities in the United States, other industrialized nations, as well as resource-limited countries,” said Ozcan, founder and director of the company. “Holomic would not have reached this stage without the support of the School of Engineering as well as ITA. I am thankful for their support.” According to Les Lackman, deputy director of ITA, the Institute helped spin off two successful companies prior to Holomic. One is WaveConnex, Inc. with Frank Chang, distinguished professor and chair of the Electrical Engineering Department and the other, Easel Biotechnologies with James Liao, professor and vice chair of the Chemical and Biomolecular Engineering Department. “ITA is a leading organization that helps incubate advanced breakthroughs from our research labs to industry, with the goal of streamlining the creation of products, processes and services that fill the needs of society,” said Dean Vijay K. Dhir about ITA when it first opened. “This new institute adds an important

Lixia Zhang

named to Jonathan B. Postel Chair in ComPuter sCienCe Wileen Wong Kromhout

ixia Zhang, a professor of computer science, has been named the holder of the Jonathan B. Postel Chair in Computer Science. The chair, established through an endowed fund initially created by a distinguished group of Jonathan Postel’s friends and family, honors the famed computer scientist’s lifetime achievements. Known as one of the Internet’s pioneers, Postel was a three-time graduate of UCLA Engineering, where he received his bachelor’s and master’s degrees in engineering and his Ph.D. in computer science. As part of professor Leonard Kleinrock’s ARPANET team at UCLA, he was one of the programmers who helped create the Internet’s precursor. After graduation, Postel continued his research at the nonprofit MITRE Corp. and the Stanford Research Institute (SRI) before moving on to a 21-year career at the University of Southern California’s Information Science Institute. His research contributions included Internet protocol design and verification, multimedia computing and communications, electronic commerce, the Internet domain-name system, and a range of additional Internet protocols. Over the years, Postel became a leading spokesman for and architect of systematic organization in the rapidly growing online community and was recognized worldwide for his major role in the development and management of the Internet. He died in 1998. This chair is one of two at the school established in honor of Postel. The other, the Jonathan B. Postel Chair in Networking, is held by Deborah Estrin, a distinguished professor of computer science. The Postel Chair in Computer Science is intended for a faculty member of significant stature in computer science who will continue the great strides Postel made in Internet-related research. In 1999, Zhang coined the term “middlebox” to refer to the new components that are not in the original IP (Internet protocol) architecture. The term was quickly picked up by the community and is now used everywhere. Zhang’s research group has been tackling topics like

Bioengineering Professor

named Packard Foundation Fellow Matthew Chin

he David and Lucile Packard Foundation has named Dino Di Carlo, assistant professor of bioengineering, a 2011 recipient of a Packard Fellowship for Science and Engineering. He was among 16 recipients in this year’s class of Packard Fellows. The Fellowship Program was established in 1988 and arose out of David Packard’s commitment to strengthening research groups that are the heart of universitybased science and engineering programs. By supporting unusually creative professors early in their careers, the Foundation hopes to develop scientific leaders, to further

the work of promising scientists and engineers, and to support efforts to attract talented graduate students into university research in the United States. Di Carlo will apply the unrestricted grant to conduct research on using the mechanical properties of a cell, rather than molecular properties, as clinically useful and low-cost indicators of a patient’s health. This approach takes advantage of microscale fluid physics to sequentially align, squeeze, and measure thousands of cells per second to potentially identify cancer, infection, and transplant rejection. “The real hope is to develop an automated approach to take advantage of the differences in varied physical properties amongst cells to enable inexpensive clinical diagnostics,” Di Carlo said. “We have been pioneering precision techniques to engineer and control cell positions in flowing fluids and we are taking advantage of this expertise to stretch and analyze cells quickly using purely fluid-induced forces.” Di Carlo is developing a technology to measure the mechanics of thousands of cells per second in an automated fashion. The technique relies on the ability to flow cells one by one at high rates into a fluid wall and capture the changes in cell shape upon hitting that wall with a high-speed camera that can snap over 100,000 photos per second. Software then automatically identifies the cells and extracts information concerning the changes in cell shape that can be reported back to the end user, such as the doctor, in an easy-to-read format. Di Carlo anticipates the approach, if successful, could find broad applications in cases when the physical properties of cells reflect disease state, as in screening for cancer, identifying infection, or monitoring transplant patients for rejection.

Electrical Engineering Professor receives Prestigious Pecase award Wileen Wong Kromhout

ydogan Ozcan, associate professor of electrical engineering and bioengineering, has received the country’s highest honor for science and engineering researchers who are at an early stage of their careers. Ozcan was one of 94 researchers recently announced by President Obama, as recipients of the Presidential Early Career Awards for Scientists and Engineers (PECASE). Ozcan’s research is in photonics and its applications in nano- and bio-technology. Most prominently, he has developed new powerful optical imaging and sensing architectures that can be incorporated into mobile phones. Essentially becoming mobile labs, these phones can analyze fluids to test for HIV, malaria, and other infectious diseases in body fluids, or analyze water quality following a disaster. These devices, which are relatively inexpensive to produce, have broad applications for improving health care in resource-poor regions. “I’m very honored to receive the PECASE award,” Ozcan said. “This will support our existing efforts to create smart global health systems through innovative uses of photonics and computational technologies.” “Ozcan’s research in photonics applications, in particular his work with mobile phone platforms, holds great potential, and he is a truly deserving recipient of this honor,” said Dean Vijay K. Dhir. “This award also

reflects the excellence of the school’s faculty, who are committed to conducting research that addresses the critical needs of the country across many areas.” Ozcan has already received several prominent honors for his research, including the National Science Foundation CAREER Award; the National Geographic Emerging Explorer Award; the National Institutes of Health Director’s New Innovator Award; Young Investigator Awards from the Office of Naval Research and from the Army Research Office; MIT’s TR35 Award, IEEE Photonics Society and SPIE Young Investigator Awards, and a Grand Challenges Explorations Award from the Bill and Melinda Gates Foundation. The PECASE award recipients are nominated by 16 federal department and agencies. The recipients’ early accomplishments demonstrate the greatest promise in continuing America’s preeminence in science and engineering. Ozcan’s nomination was from the Department of Defense. Ozcan is also a member of the California NanoSystems Institute (CNSI).

Bioengineering Professor

named nIH new Innovator Matthew Chin

ndrea M. Kasko, assistant professor of bioengineering, has received a 2011 NIH Director’s New Innovator Award from the National Institutes for Health (NIH). The NIH award program supports exceptionally creative investigators at an early stage in their career who have proposed highly innovative projects. These projects hold potential for a significant impact on an important biomedical or behavioral research problem. The research grant is for $1.5 million over five years. The award supports Kasko’s research in utilizing light-responsive biomaterials to fabricate and manipulate chemically and physically complex three-dimensional cell microenvironments. The research has applications in developmental biology, tissue engineering, regenerative medicine, therapeutics and disease models. “It’s a great honor to be selected for the NIH Director’s New Innovator Award,” Kasko said. “This particular award allows us to tackle a large and complex problem that is, how can we recreate the natural environment of cells and use it to understand their behavior and discover new therapies – without having to break the project up into several smaller projects. Being able to assemble a larger team to simultaneously explore multiple areas allows us to work at a more rapid pace and to get a much more complete picture than we would otherwise be able to do. We’re excited to see where this research takes us.” Kasko leads a research group that works with hydrogels, which are widely used for three-dimensional cell culture because they recapture some of the important properties of the natural environment of cells, such as high water content. “What is unique about our approach is we have incorporated chemical groups into our hydrogels that respond to light,” she said. “This allows us to change the environment around the cells, for example, by releasing a drug, or making the material softer.

Andrea Kasko

Light-responsive biomaterials can help create physically and chemically complex 3-D scaffolds for cells. Precise control over biomaterial properties in 3-D is critical to capture the complex cascades of signals and complex microenvironments found in nature. Down the road, generating accurate 3-D models of tissue, whether healthy or diseased, could help researchers understand how that tissue develops or heals, and how it responds to its environment. Kasko is the fifth UCLA Engineering faculty member to receive the NIH Director’s New Innovator Award in the past three years.

Shioupyn Shen phD ’91:

ThE PoWEr AND rESPoNSIBILITy oF LEADING yoUr oWN CoMPANy Wileen Wong Kromhout

Shioupyn Shen, who studied under the advisement of Leonard Kleinrock, distinguished professor of the Computer Science Department, received his Ph.D. from UCLA Engineering in 1991. Upon graduation, Shen had a successful career working for companies like Microsoft and Google. At Microsoft he worked on NT Networking, Directory Service and SQL Server. At Google he worked on Gmail, Ads Syndication and Google WiFi. Shen, with the opportunity to observe the tech titans from the inside, acquired a vast array of industry experience. In 2009, he founded CloudMosa, Inc., with the mission to revolutionize the Web experience on mobile devices through cloud computing. The company developed the Puffin Web Browser — with the goal of making it the fastest and most powerful Web browser on mobile platforms.

How did the opportunity to start your own company come about? Shen: One of the most crucial skills for success is the ability to screen ideas quickly and to pursue opportunities early. I am a hands-on person with a technical and analytic background to evaluate ideas keenly. In 2006, I was designing an inexpensive tablet computer – my version of OLPC (One Laptop per Child) — with a far superior Web browser. With the launch of the iPhone in early 2007 and the EeePC in late 2007, I realized that a hardware revolution had started. When Amazon EC2 came out of Beta in late 2008, I knew the timing was right. I took a leave of absence in early 2009 to implement a prototype, and then decided to devote myself full time to pursue this opportunity.

Was it a hard decision to leave Google to run a start-up? Leaving Google was one of the hardest decisions of my life. Google was named the best company to work for in recent years. However, mobile Internet and cloud computing offered some of the best opportunities in decades. I asked myself “what would I do if I could do anything,” and the decision became obvious — choose the path with more interesting challenges and far superior opportunities than staying in my comfort zone.

Shioupyn Shen

What is the biggest challenge of starting your own company? One of the biggest challenges I had to face was hiring; it is challenging to compete with top tier companies when it comes to recruitment. Additionally, many highly skilled and successful engineers had already retired to pursue other interests. The best candidates are founders of failed start-up companies, who are hard to find and difficult to recruit. Fortunately, the timing was a blessing for CloudMosa; in early 2009, many excellent engineers became available because of the global financial crisis.

For someone who has had the experience of being on both sides, what advice would you give a student deciding which path to take? Regardless of which path a student takes, my best advice is to be analytic, i.e., to develop the mathematical skills to be comfortable with numbers. When “it doesn’t add up,” the subtle clues are more obvious to those who are more sensitive to numbers. In terms of career choice, it is mostly determined by personality. Are you a passionate person or a disciplined person? Passionate people make better entrepreneurs but must be cautious because “curiosity kills the cat.” Disciplined people are better at climbing the corporate ladder but must be able to take risks because “care kills the cat.”

What advice would you give an alumnus trying to make a similar career transition? Nowadays, the line between an engineer and an entrepreneur has blurred, and it is common for someone to transition back and forth depending on the opportunities available. My best advice is to alternate between the two worlds. First, be an entrepreneur in graduate school when the cost is the lowest. If unsuccessful on the first try, then work for one of the most selective companies right after graduation. Work hard to build a superb technical reputation and wait for some over-achieving bosses to become entrepreneurs.

What has been the best part about running your own company? With great power come great responsibilities. If I took too much pleasure in my power, I would have failed my responsibilities. The best part is not the pleasure but the experience — an experience to make each day count. Every morning when I wake up, I am glad that the company is still growing. I must treat every day as the best opportunity to improve the company as well as the last chance to help the company survive. In terms of being my own boss, it is just a façade; the wife is always the real boss.

What about your education/experience at UCLA Engineering has contributed to your career success? The value of education is intangible; it shapes our character more than builds our skills. During my time at UCLA, I received an excellent foundation on which the rest of my career was based. I was very fortunate to have Dr. Kleinrock as my thesis advisor. In addition to the classroom lectures and thesis advice, the most valuable asset I acquired was self-confidence — it made me a strong enough person to plow through the darkest days of my career.

Louis G. Walters ’47, MS ’49, PhD ’51 former assistant professor and adjunct associate professor, UCLA Engineering

George Bekey ’50, MS ’52, PhD ’61 has published another book. Robot Ethics is co-edited with P. Lin and K. Abney from the philosophy department at the California Polytechnic State University at San Luis Obispo. The book was published by MIT Press, 2012. His previous book Autonomous Robots was also published by MIT Press in 2005.

My principal Faculty responsibilities were the management of the automatic control discipline and the off-campus UCLA Engineering programs to extend the UCLA footprint to engineering centers throughout Southern California. I served as engineering professor in residence at the China Lake Naval Air Station (1951-1952) and later in San Diego, offering graduate seminars in automatic control theory, critical to the aerospace industry in that area. I had co-founded an aerospace engineering enterprise which Ford Motor Company quickly acquired. Within weeks, Samuel Herrick (professor of astronomy at UCLA) and five of his graduate students joined in a UCLA team effort to provide orbit determination technology and software for the Air Force centers for satellite R&D (Air Force Satellite Test Center) and operations (Air Force Space Command). The engineering context of the historical astronomy practice was named “astrodynamics” and incidentally, each of Herrick’s graduate students achieved their academic objectives through an off-campus graduate program in Orange county, hosted by Ford. I managed the development and technical evolution of astrodynamic products for these centers for four decades, ending as a member of the Air Force Science Advisory Board committee on Space Surveillance, Asteroids and Comets. The unusual combination of educational opportunities between 1943 and 1945 was in preparation for a military assignment (Philippines) to establish a radar network capable of tracking weather balloons to extreme altitudes, to understand difficulties in scheduling B29 flight schedules in the SW Pacific. The effort clocked wind speeds of over 200 knots, now described as the “jet stream.” I retired at age 80, and now divide my time between Washington state and Keauhou, Hawaii.

Infrastructure resIlIency continued from page 5 understand how the ground motion scales with the source parameters, magnitude, the distance from the source, the site, and various other factors. Then try to get the best models we can to describe that.” In Los Angeles, Stewart is working on the issues involving non-ductile concrete buildings — older buildings whose structures are made up of unreinforced concrete that predate standards set following the 1971 Sylmar earthquake. “The idea here is to, at a very broad scale, come up with methodologies to identify the buildings presenting the most pronounced collapse risk, the killer buildings.” Stewart’s long-term research interest is understanding the complex behavior associated with the interface between the foundation of a structure and the supporting soil. Stewart recently led a large, multi-disciplinary team in developing a national standard for modeling such effects, based on the best engineering Scott Brandenberg and the NEES@UCLA team on their science coupled with carefully executed experiresearch site in the Delta. ments performed at field-scale.

the sacramento/san joaquin delta is a large estuary that lies between the Central Valley and Suisun Bay at the confluence of the Sacramento and San Joaquin rivers. A system of levees, dating back to the mid 1800’s protects the Delta “islands” that lie mostly below sea level due to subsidence caused by oxidation and erosion of the unusual peaty organic soils. The Delta serves as the hub of California’s water delivery system that serves over 23 million residents, and provides the sole source of water for many communities. It also is near the eastern margin of the San Andreas fault system, and there are concerns that an earthquake could cause simultaneous flooding of many Delta islands, inundating farmland and wildlife habitat. This “big gulp” scenario would draw in saline water from the West, contaminating fresh water in the Delta to the point that water delivery could be halted. This would be a truly disastrous scenario that some have deemed “California’s Katrina.” However, very little is currently known about the seismic response of peaty organic soil. continued on page 32

To assess how levees would respond in an earthquake, associate professor scott brandenberg and Stewart are leading a project on the deformation potential of the levees. The research team conducted a field test last summer with one the NEES@UCLA eccentric mass shakers. “We are going to look at how the energy from the relatively stiff embankment was transmitted into the peat to help us understand how seismic energy coming up from the peat would be transmitted into a levee during an earthquake,” Brandenberg said. The research team is processing the data from that onsite test as well as conducting more research in the laboratory. They have also proposed a second field test with the water level closer to the surface, as well constructing a model levee to shake on a geotechnical centrifuge. “The improved knowledge of levee seismic vulnerability will be broadly applicable wherever these earth structures are founded on organic soils,” Brandenberg said. Brandenberg and Stewart are also involved in a study of levee performance during past earthquakes to help advise decision-making on important levees in California, and a laboratory testing program to study the behavior of peaty organic soils. associate professor ertugrul taciroglu is the principal investigator on a NEES@UCLA field project in Istanbul, Turkey. Collaborating with colleagues from Bogazici University and the Kandilli Observatory and Earthquake Research Institute (KOERI) the research team examined the behavior and performance of an older reinforced concrete building. Field testing began in 2010, on a standard four-story building with a concrete frame and masonry infill. The building was then stripped to its frame and retrofitted with improved seismic design. A structural monitoring system was set up in the building to monitor its ambient vibration. Then in December of that year, it was subjected to forced vibration testing. Ertugrul Taciroglu (left) and collaborators at the Istanbul building test site.

One of the things we sought to find out from test data was the contribution of masonry infill to the dynamic characteristics of this non-ductile reinforced concrete building,” Taciroglu said. “This in turn influences how the forces induced by an earthquake are distributed throughout the structural frame.” Much of Turkey lies between the Anatolian Plate and faults along it have produced earthquakes greater than magnitude 7.0, including a 7.2 quake in Eastern Turkey in 2011. “We found that the said contribution from infill walls to structure’s apparent natural vibration frequencies and damping are significant enough that they can not be ignored in forward numerical simulations,” he said. “This is very much in line with findings from other similar studies, and at least for buildings in Turkey, more field tests are warranted to bracket and model the infill behavior.” The Istanbul test building is not only typical of many residential, government and commercial buildings in Turkey, it’s also similar to pre-1973 buildings in California. Following the 1971 Sylmar earthquake, California state buildings codes were improved. However, many of these earlier buildings still remain throughout the state. these are just a few examples of research being conducted by UCLA engineers. Much of the engineering research related to earthquakes is very collaborative with UCLA faculty and students working with colleagues in California and around the world; in academia, government and industry. “We’re doing some good fundamental work,” Stewart said. “The world will hopefully be a better place because of these types of projects. And UCLA is right in the middle of it all.” Wallace added, “It’s exciting work that has an unusually high impact on engineering practice, and it enriches our classroom teaching.” To find out more about earthquake-engineering related research at UCLA, visit the Web site of the Civil and Environmental Engineering Department: www.cee.ucla.edu and the NEES@UCLA Web site: www.nees.ucla.edu
