Letter from the Chair It has been a truly remarkable year here in the School of Civil and Environmental Engineering. For a second academic year, we navigated the realities of living and learning in the midst of a global pandemic. But despite the challenging circumstances, I’m happy to report that we not only survived, but thrived. For the first time in School history, our undergraduate civil engineering program was ranked No. 1 in the nation by U.S. News and World Report. After a steady rise in our rankings over the years, it was gratifying to earn the top spot and see our students, faculty and staff receive this recognition on the national stage. The School also received two prestigious grants that will help us to elevate our success even further by providing us with resources to create innovative changes to our curriculum and culture. The National Science Foundation’s Revolutionizing Engineering Departments (RED) Grant will help us to develop new courses and engagement opportunities to enhance students’ connection to the civil and environmental engineering professions while creating a sense of belonging in a safe and inclusive environment. And thanks to the Kern Family Foundation, CEE will be able to join other programs in the College of Engineering to infuse story-driven learning into our curricula and help students build entrepreneurial mindsets. In addition to these awards, so many of our students and faculty were recognized for their individual achievements with a variety of impressive accolades. Our faculty members have earned recognition for their accomplishments by national industry and society groups as well as honors from Georgia Tech for the excellent instruction they provide. Our civil and environmental engineering students are equally impressive, with awards for their prowess in research, innovation and design. There is so much more that I am excited to share with you in the following pages. I hope you will enjoy learning more about what we’ve been up to in the 2020-2021 academic year. I am proud of all we’ve accomplished and look forward the many exciting things to come. Thank you for reading and supporting the School of Civil and Environmental Engineering. Go Jackets!

Civil Engineering Ranked No. 1 In the Nation

ivil Engineering at Georgia Tech is now the topranked program of its kind in the nation. U.S. News and World Report has released its 2021 list of the country’s best undergraduate engineering programs, featuring Georgia Tech civil engineering at No. 1 and environmental engineering at No. 4. Civil engineering was ranked No. 1 for the first time, up from the No. 2 spot over the past four years. Environmental engineering maintained the No. 4 ranking for the third year in a row. “This recognition is well-deserved and reflective of the students, faculty and staff that we have long felt are the best in the nation,” said Karen and John Huff School Chair Don Webster. “While this is welcome news, it does not come as a surprise. We in the School of Civil and Environmental Engineering have dedicated ourselves to continually improving our educational programs, which is reflected in our steady rise through the rankings over the past 10 years. We are thrilled to be recognized as the top civil engineering

Creating a Community Love of reading, engineering, unites students during pandemic

s the pandemic dragged into 2021, Maria Warren found herself reading more and more. With Covid-19 shelving her go-to leisure activities like playing soccer and meeting friends for coffee, the Ph.D. student turned to books in her spare time and decided to reread one of her favorites: BUILT by Roma Agrawal. “This book made me fall in love with structural engineering again,” Warren said. In 2020, Warren was selected as one of the School of Civil and Environmental Engineering’s Future Faculty Fellows. The four-year-old program supports students pursuing careers in academia through a $1,000 stipend to guide their development as educators and help them build their research and professional relationships. But like soccer and coffee shops, Covid-19 took traveling to conferences off the table, and spending the money to attend virtual conferences just didn’t have the same appeal for Warren. So she came up with the idea of bringing the CEE community together for a book club to read and talk about the book that had been so influential for her. Using her Future Faculty Fellows stipend, Warren committed to purchasing a book for any student interested in participating. She also made the club open to everyone in CEE—students, faculty and staff—with the goal of creating a sense of community for the School during a time when so many were working and studying remotely. With its accessible style and broad overview of structural engineering history, Warren thought BUILT would be the perfect way to kick off the book club. “It is technical, but it’s written for a beginner,” said Warren, who co-teaches an introduction to structural

engineering for undergraduates. “This was a really good book because it’s for people who are not as experienced on the technical side, but also I love structural engineering and I’ve read it three or four times over.” At the start of the Spring 2021 semester, Warren created a flyer and spread the word about the CEE Book Club. She joked about her initial worry that the club might just be her and a few friends that she guilted into joining. But it turns out that Warren was onto something: Lots of people signed up to participate, and roughly 30 people attended each virtual meeting. While the book focused on structures, book club participants represented a cross-section of the School and included students from other disciplines like transportation and water systems engineering. Tobias Kopp, a rising fourth year student, said he was intrigued by the book club’s focus on structural engineering—an area he didn’t know much about. “The book club was an all-around amazing experience and I applaud Maria for getting the book club up and running during such a challenging time,” Kopp said. “I enjoyed hearing other students’ thoughts on the discipline, and one of the best things I took away were the amazing stories others shared of their experiences in structural engineering either 6

from an internship or research.” Francesca Lolli, a second-year post-doctoral researcher, said it was nice having the opportunity to interact with different people during the group discussions. “Every time I met new people with very different backgrounds, so the conversation was always very stimulating,” Lolli said. “My take away is that we should probably integrate more ‘soft’ reading at the university level. I think that focusing on why we built cities in a certain way and how history is connected to the built environment is something that we don’t think enough about during more traditional courses.” For the group’s last meeting of the semester, Warren decided to try something bold. She emailed Agrawal, the author of the book, and asked if she would be willing to join the virtual meeting and answer a few questions. To Warren’s delight, she said yes. Agrawal beamed in to the CEE Book Club’s April 23 meeting from her home in the United Kingdom, where she shared her career journey with the group and answered questions about sustainability, ethics and the future of civil engineering. Agrawal is a structural engineer who has worked on several notable buildings in London’s skyline, including The Shard, the tallest building in western

Europe. Agrawal said over the years, she gave lots of presentations about these high-profile projects, and found she had a knack for explaining complicated subject matter. She was approached by a publisher with an offer to write a book, which became BUILT: The Hidden Stories Behind Our Structures. The 2018 book combines history, technical explanations and personal anecdotes to explain the evolution of construction over time. As an aspiring professor, leading the CEE book club gave Warren a new perspective on teaching. “The book club has been super interesting because I’ve taught Introduction to Structures and Civil Engineering Materials, and those are really technical classes,” Warren said. “With the book club, I’m leading a discussion-based class. It’s been interesting to learn how to moderate discussions and ensure that everyone who wants to participate can. It’s been a challenge but it’s been a lot of fun.” Following its successful debut, plans are underway for the book club to continue in the fall. The basic structure will remain the same. The group will read one book and discuss it in several meetings over the course of the semester. But there will be one major change—participants will gather on campus instead of on their computer screens. Warren hopes that the book club will continue to thrive and provide more opportunities for people in CEE to get to know each other and interact face to face. “I feel really grateful to everyone in the CEE community who has supported and joined and shared it with their friends,” Warren said. “The participants in the book club are so enthusiastic and the discussions are so fulfilling. They’ve made the experience so great and I’m really grateful for them.”

CEE Introduces Construction and Infrastructure Concentration

ivil engineering students are now able to earn a concentration in Construction and Infrastructure Systems Engineering (CISE), an official designation that lets employers know they are ready for careers in the construction industry. In Fall 2020, the School of Civil and Environmental Engineering began offering its construction and infrastructure courses in a formal concentration that will be recognized upon graduating with a civil engineering degree. “The CISE concentration is unique to civil engineering and to the School of Civil and Environmental Engineering at large,” said Eric Marks, a professor of the practice in civil engineering. “The concentration was created in tandem with our construction industry partners. Having this designation will enable our program to closer align with the needs of the industry and better equip our students for successful careers.” Students pursuing the CISE Concentration are able to specialize in two tracks: Construction Engineering and Management and Infrastructure Systems Engineering. Infrastructure Systems Engineering focuses on the facilities required to support societies and

thriving economies: roadways, bridges, tunnels, water treatment facilities, electrical grids, telecommunications and more. Construction Engineering and Management professionals implement innovative technologies, design and facilitate construction projects with sound engineering principles, and align a multitude of stakeholders while leading capital-intensive construction in the industrial, heavy civil, commercial and residential sectors. Students in the CISE Concentration will take elective courses that allow them to specialize in construction management and infrastructure, while earning a degree in civil engineering. The concentration was designed by faculty and an advisory board of alumni and industry professionals. Paul Carter is the Walsh Group’s senior vice president of the Southeast Division and a member of the School’s CISE Advisory Board. Carter says that the coursework and opportunities provided by this new concentration will set students apart in their knowledge of multiple aspects of construction projects. “We see the CISE Concentration as a bridge between business management and civil engineering degrees, which thrive in our line of work,” Carter says. “These courses will help the students build successful careers in the ever-evolving fast paced construction industry.” Blake Peck, MS CE 78, is the CEO of construction management firm MBP and a member of the School’s CISE advisory board. Peck says for employers like himself, the concentration adds extra appeal to Georgia Tech’s civil engineering graduates, who are already in high demand. Civil engineering students will graduate even more prepared for jobs in the construction field. The CISE Concentration will allow students to clearly communicate to employers their level of construction industry knowledge. “If they haven’t taken a construction scheduling class, or a cost estimation class, we’re really starting at ground zero. But if they’ve had those electives, they come in with an understanding of the industry,” Peck said. “They’re six months to a year further along than their peers if they come in having taken those electives.” Students will also have more exposure to interdisciplinary coursework that will differentiate them from their peers in more traditional programs—something firms in the construction industry are looking for, Carter said. 8

RED Grant Brings New Possibilities T

he School of Civil and Environmental Engineering has been awarded a $1 million grant from the National Science Foundation to develop innovative changes to the School’s curriculum and culture. Known as a RED grant—Revolutionizing Engineering Departments—the funding will be used to create resources to instill in students a greater sense of understanding and belonging to the civil and environmental engineering fields. “We are thrilled to receive this support that will enable us to begin developing new courses to enhance our undergraduate experience,” said Karen and John Huff School Chair Donald Webster. “This is a phenomenal opportunity to think holistically about our curriculum, particularly framed around a sense of belonging through an instructional thread that will connect each year of our undergraduate degree programs.” The RED grant will be used to enhance students’ connection to the civil and environmental engineering professions while creating a safe and inclusive environment for all CEE students, particularly women and underrepresented minorities. The funding will also help to increase engagement for students throughout their undergraduate studies and improve student retention within the School. CEE programs across the country struggle with retention. A main culprit is that students often

aren’t significantly engaged with civil and environmental engineering material until after they’ve completed their core courses halfway through their college experience. School leadership concluded that early and continuing engagement in the discipline would help keep more students in the program. Associate Chair Kevin Haas and Assistant Professor Emily Grubert developed a course called “Exploring CEE” as a way to engage undergraduates during their first year in the program. The course, which was offered for the first time in Fall 2019, introduced first-year students to the work civil and environmental engineers do through interdisciplinary research topics, guest lecturers and team problem-solving exercises. “It’s been a real pleasure to watch students realize the scope of what we do as a profession, while simultaneously realizing that we’re a supportive community with a ton of interests,” Grubert said. “I’m very excited to continue developing this class in the context of the RED grant, knowing that there will be a clear path forward for the students to continue those kinds of discoveries as they gain skills.” With the RED grant, the School aims to build on the Explore CEE class by developing a series of courses that will ground students in the kind of work they will be doing as civil and environmental engineers. Over the next five years, the School will develop and implement a spine of four mutually informing and highly interactive courses with an emphasis on problem-finding and problem-solving. The courses will address society’s grand challenges and help students develop computational, teaming, and reflection skills. Each course will build on the last, with increasing rigor, ending with the Capstone senior design class. “This RED grant will support us to enhance the quality of our civil and environmental engineering curricula,” said Adjo AmekudziKennedy, associate chair for global engineering leadership and entrepreneurship. “We will be able to do all this in an integrated and thorough manner – improving the internal climate and programs while enhancing the impact of our graduates beyond CEEatGT, with contributions to advance engineering education scholarship.”

KEEN Grant Expands Story-Driven Learning for CEE Students

Students are asked to reflect on what they’re learning and how it connects to their own life experiences. They also spend time doing peer reviews and interviewing people to discover real-world problems to solve and understand user needs. The new grant expands these ideas into the other programs, scaling up story-driven learning. “It’s really exciting, because 40% of College of Engineering students will be impacted,” Le Doux said. “Every civil, environmental, aerospace, and CREATE-X student will get it — but in different ways.” In the School of Civil and Environmental Engineering, the project will build on a larger, multi-year effort to transform the School’s culture and curriculum by improving students’ sense of belonging and connection. School leaders are designing a series of four vertically integrated courses focused on interactive problembased learning and problem solving around the grand societal challenges that civil and environmental engineers work to solve. The classes will feature elements of computational and team development, include reflective teaching and learning, and aim to create a greater sense of belonging among civil and environmental students. “The overarching objective of this initiative is to incorporate entrepreneurially-minded learning pedagogies into our engineering programs, with a focus on value sensitive design and story-driven learning, to support the development of entrepreneurially minded engineers,” said Adjo Amekudzi-Kennedy, associate chair and professor in the School. “That means engineers who have a mindset and culture of value creation: for society, for the advancement of the economy, and for themselves in ways that formally incorporate societal values and minimize negative consequences.” — By Joshua Stewart

torytelling is how we share ideas and culture. It’s how we build relationships. Telling stories also helps us learn and integrate that new information into our existing knowledge, which is partly why helping students tell their stories has become an important part of the curriculum in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. Now the idea is reaching other disciplines in the College of Engineering at Tech with the support of a $3.1 million grant from the Kern Family Foundation. Under the new project, led by Coulter BME Professor Joe Le Doux, the Daniel Guggenheim School of Aerospace Engineering, the School of Civil and Environmental Engineering, and the College’s CREATE-X entrepreneurial program will infuse story-driven learning into their curricula to help students build “entrepreneurial mindsets.” The idea is to help students see themselves as engineers ready and able to act, using all the skills they’re learning to solve problems and improve the human condition. “Throughout engineering education, I would argue, we often don’t give students a chance to sit back, reflect, and make connections about what they’re learning and how they can use it,” said Le Doux. “Some students do it on their own. But some don’t. Those who do, really benefit from it. So, the whole concept of the storydriven learning piece is to help students make these connections about what they’re learning, who they are, where they’re going.” The Coulter Department has been developing this story-driven learning idea for a few years through the Foundation’s Kern Entrepreneurial Engineering Network (KEEN). It has developed into a thread that weaves throughout students’ courses: All along their journey, students have significant learning experiences that add to their bank of stories.

Tackling Affordable Housing in Atlanta

uring the fourth annual Tech Blitz, six teams of students and industry professionals focused on ways that civil engineers can innovate within the construction industry to bring down costs and help combat rising rent prices across the city of Atlanta. The event, hosted by the School of Civil and Environmental Engineering, is an all-day hackathon with a focus on pushing the technological boundaries of the construction industry. This year, the teams were challenged to utilize prefabrication and modularization construction principles to decrease construction costs by 70 percent without significantly impacting other project controls like safety and quality. The event featured a panel of guest speakers that educated the teams about the scope of the issues surrounding affordable housing as well as some of the emerging solutions that can be utilized to lower construction costs. Atlanta’s Chief Housing Officer Terri Lee and Bithia Ratnasamy, a project manager in the Office of the Mayor, spoke about affordability in the city of Atlanta. Affordable housing can mean many things: homes for sale or for rent, homes that are subsidized by the government to keep prices low, or housing that is naturally at a lower price point through cost-effective construction or other market forces. Affordability is also different for a single person than a family of five. Ratnasamy said a good metric for affordable housing is a home that costs no more than 30 percent of any household’s monthly income. Darion Dunn, CE 00, is a member of the School’s External Advisory Board and a managing partner at Atlantica Properties. Dunn said there are other important factors to consider when thinking about the issue of affordable housing, including population density. More than two million people are projected to move to the metro Atlanta area over the next 20 years. Meanwhile, as housing near job centers gets more expensive, people move farther away to find more affordable housing and spend a higher percentage of their income on transportation to and from work. “You cannot talk about affordable housing without talking about population density and transportation, and these are two things the civil engineering community can help with,” Dunn said. Prefabrication and lean construction principles are also important ways for the construction industry to tackle the affordable housing problem, Dunn said. “The total construction costs go down, which makes debt go down, which makes the monthly payments go down for an apartment owner, which affects the rent,” Dunn said. Following a full day of brainstorming, the teams

presented their proposals to a panel of judges. The winning project proposed revitalizing a historic structure while adding affordable housing through modular building. The group selected Paschal’s Motor Hotel, a historic building in disrepair located on the west side of Atlanta that served as a meeting place during the civil rights movement. Through selective demolition on a portion of the existing motel, the group proposed implementing modularization to create 110 housing units. Proposed cost-saving measures include the reestablishment of the motel’s restaurant to produce retail leasing fees to offset the renovation debt; advanced framing techniques to reduce material costs by 15 percent; and ductless mini-split heating and cooling systems to eliminate the cost of installing ductwork. The group speculated that additional savings could come in the form of tax credits that the project could qualify for in addition to a potential partnership with Clark Atlanta University, which currently owns the building. The team behind the proposal was comprised of four students and four industry professionals: Tech students Ali Lopez, Victoria Lynn, Sandra Diaz and Tobias Kopp, along with Preston Jutte from Kimley-Horn, Alex Darr from Pond, Diana Sacks of SK Collaborative and Vincent Harvey from Turner Construction.

EnvE Grad to Engineer Clean Water Solutions Abroad E

lisabeth McDonnell, an environmental engineering graduate from Roswell, Ga., packed up to leave the country for two years just days after graduating in December 2020. In January, McDonnell headed to Sierra Leone to work for a company called Water4. With locations in more than a dozen African countries, Water4 helps empower local communities to lead projects that bring them clean water. This opportunity came from a partnership between Water4 and Georgia Tech’s Campus Christian Fellowship (CCF). In Sierra Leone, McDonnell will help engineer solutions to bring clean water to various communities. But she’ll also have a hand in creating an internship program specifically for Georgia Tech engineers who want to come do the same thing. She’ll be overseeing three to four students at a time in their work with Water4. McDonnell was initially drawn to environmental engineering by her love for animals, but a mission trip in high school set her on the clean water track. Halfway through her stay in Kenya, the compound she was living in experienced a water shortage. For the rest of their time there, she and her group had to walk three miles to get their water for the day. “I realized that for some people, this is what they do every single morning for their whole lives,” McDonnell said. “That’s when water sanitation came to the forefront of my mind.” She feels confident that her degree program’s emphasis on creativity and problem solving has equipped her with the skills necessary to tackle these problems. “All of the classes I’ve been in have encouraged ingenuity and creativity in solving problems in a way that’s different than the status quo,” she said. McDonnell also learned meaningful lessons outside of the classroom, most notably with the Ramblin’ Reck Club. Since joining in her second semester at Tech, McDonnell has held multiple leadership positions within the organization, including traditions chair and vice president. To her, the Reck Club served as a way to show her Georgia Tech spirit, as well as a reminder of just how passionate her fellow students can be. “People in Reck Club remind you that you’re blessed to have the opportunity to be stressed over the potential to achieve exceptional things,” she said. After graduation, McDonnell will have no shortage of fond memories to look back on from her time at Tech, including Midnight Bud, a finals de-stressing event on campus. At the end of her first semester, McDonnell, who had never heard of Midnight Bud, was caught off guard one night by the sound of students singing Georgia Tech songs outside her dorm. She and her friend headed outside, barefoot and in pajamas, and ended up following the crowd all the way to the North Avenue Apartments — and having the time of their lives. “When I needed it most, I was reminded of how special Georgia Tech is,” she said. — By Grace Wyner 13

Nontraditional Student Makes the Grade T

imothy “TJ” Weiler, 43, was a nontraditional student with an unusual educational background. He graduated in December 2020 with a Georgia Tech degree in civil engineering with a focus on structural theory. Weiler, whose hometown is Athens, Greece, grew up traveling the world with his parents, who were engaged in missionary projects. As a result, he did not get a chance to regularly attend school. When he was in his thirties, he decided he wanted to get a proper education and become a structural engineer. “I began my academic journey by getting my GED, enrolling in community college, and teaching myself basic math,” he said. He worked his way up to advanced engineering classes and eventually transferred to Georgia Tech. “I am beyond grateful that I was accepted into Georgia Tech, the no. 1 college for civil engineering in the country. It’s truly been a dream come true,” Weiler said. His time at Tech overlapped with his nephew, Derek Weiler, who graduated last spring with a degree in computer science. His niece, Cherish Weiler, has a master’s degree from Tech. He said that any time he would tell someone he was at Tech, they would ask if he was a professor. His reply? “No, I’m just a very old student,” he laughed. And although he is relieved to be completing his degree, he will miss the intense academic challenges he faced — and overcame — at Tech. He, like his fellow students, also had to deal with the isolation caused by the pandemic. “There certainly was a lot more stress involved, even though I did not want to admit it at the time,” he said. “I missed the interaction with my classmates, and group projects were not the same on BlueJeans. The regular group dynamic was really missed.” But Weiler persevered. He said he was most looking forward to hearing his name announced during the ceremony. Weiler, who has a background in construction, will pursue a career as a structural engineer. — By Victor Rogers

Students Shine at First Annual Entrepreneurial Impact Competition

he School of Civil and Environmental Engineering has introduced a new student competition to celebrate innovation and encourage entrepreneurial endeavors. The Entrepreneurial Impact Competition began as an open call for proposals during the Fall 2020 semester. Individuals and teams of students at both the undergraduate and graduate level applied their CEE knowledge and skills to develop entrepreneurial ideas that could improve the human condition. Following a thorough review, a panel of judges selected four finalists to participate in the competition. The first annual Entrepreneurial Impact Competition was held on March 19, 2021 in a virtual format. Each of the impressive finalists gave five-minute verbal pitches of their projects before a live audience and a panel of expert judges, who followed up with sharp questions. The four finalists were: Cultúrea, which developed technology for better nutrient management; BioBuilt, who presented a novel design for a ground anchor; River Recon, which created a device to detect microplastics in water; and VoltaPure, whose project uses electricity to disinfect drinking water. The contest was judged by faculty members David Frost and Lisa Rosenstein along with alumni KP Reddy, CE 94, Kendell Renee Kelly, CE 01, and Leonidas Emmeneger, PhD CE 20—each of whom possesses unique experience in the entrepreneurship space. The student finalists had a lot on the line, competing for a chance to win one of two $5,000 prizes. Following a thorough deliberation, the judges selected VoltaPure and River Recon to win the prizes sponsored by two generous donors: Bill Higginbotham, CE 76, and the Zeitlin Family. The Higginbotham Prize was awarded to River Recon, comprised of Matthew Falcone, Erin Kowalsky, Timothy Purvis and Kaylyn Sinisgalli. River Recon designed a sensor to swiftly, inexpensively and efficiently identify microplastics in water. The sensing device works by using fluorescence, and in some cases light distortion, of plastic polymers at certain wavelengths to distinguish microplastics from soils and other interferences in water. The device works by passing water samples into a light-tight testing chamber, where it is stored in a glass tube. Light sources of different wavelengths turn on and off sequentially, and a camera takes an image of the sample’s response to each wavelength of light. The images are compiled and passed into a machine learning algorithm, which predicts which regions contain microplastics. VoltaPure, made up of Nissim Gore-Datar, Mourin Jarin and Jianfeng Zhou, took home the Zeitlin Prize for their technology, which offers an alternative to chemical water disinfection.

VoltaPure’s co-axial electrode copper ionization cell disinfects water while producing a very low and safe effluent copper concentration. The underlying mechanism behind the center electrode is locally enhanced electric field treatment, which exploits the lighting rod effect by distributing a low voltage to the modified electrode surface, significantly enhancing electric field exposure to pathogens. VoltaPure’s energy-efficient, chlorine-free technology can be integrated into point-of-use water disinfection for remote areas, developing communities and disaster regions without central water disinfection facilities. It can also be retrofitted into existing distribution systems to provide antimicrobial properties while eliminating the need for chlorination, offering clean drinking water without harmful disinfection by-products. “We are constantly amazed by the creative problem-solving and innovative ideas displayed by our students,” said Karen and John Huff School Chair Don Webster. “We hope this competition will help to boost the entrepreneurial mindset in our School and help launch the innovative ideas of our students and community.”

VoltaPure Left to Right: Jianfeng Zhou, Mourin Jarin, and Nissim Gore-Datar More than 800 million people worldwide lack consistent access to clean drinking water. This is due to the high cost of treatment plants, difficulties transporting chemicals, and the aftermath of carcinogenic disinfection by-products. VoltaPure’s novel co-axial electrode copper ionization cell enables superior water disinfection while producing a very low and safe effluent copper concentration. The underlying mechanism behind the center electrode is locally enhanced electric field treatment, which exploits the lighting rod effect by distributing a low voltage to the modified electrode surface, significantly enhancing electric field exposure to pathogens. VoltaPure’s energy-efficient, chlorinefree technology can be integrated into point-of-use water disinfection for remote areas, developing communities and disaster regions without central water disinfection facilities. As the technology scales, it can be retrofitted into existing distribution systems to provide antimicrobial properties while eliminating the need for chlorination, offering clean drinking water without harmful disinfection by-products.

BioBuilt John Huntoon John Huntoon collaborated with Georgia Tech faculty to develop a ground anchor inspired by the architecture and load transfer efficiency of plant roots. Ground anchors, used in many retaining walls and building foundations, are underground structures that resist forces attempting to pull the anchor from the ground by transferring those forces to the surrounding soil. Such applied forces are called pullout loads. The roots of certain plant species anchor the organism in the soil much more efficiently than any ground anchors currently used in civil infrastructure, making them a source of inspiration for ground anchor improvements. Huntoon and his team at Georgia Tech developed a prototype called the Root-Inspired Ground Anchor, or RIGA. This anchor consists of three primary components: a stressing element, identical to the steel cables or bars used in conventional ground anchors; an expansive root mechanism, which is initially cylindrical but expands during installation to mimic the geometry of fibrous plant roots; and cement grout, which gives the systems stiffness and protects its components from corrosion. The expansive root mechanism resists pullout loads more efficiently than the cylindrical external interface of a conventional ground anchor. 17

Cultύrea Left to Right: Abigail Cohen, Thomas Igou, Eli Berger, and Elliot Reid Water and nutrient management are top challenges in the United States, where food is grown using fertilizer derived from finite, energy-intensive nutrients and surface freshwater, shifting natural cycles out of balance. Nationally, more than 35 percent of municipal energy budgets are spent producing, distributing and treating water, where little recycling occurs. As this paradigm expands into emerging markets, strain on ecosystems will deepen, and agricultural resource demand will outpace reserve supplies. Rather than maintaining the status-quo, Cultúrea implements technologies to enable a more circular approach to water and nutrient management that will preserve precious resources, leapfrog linear consumption, and jump straight into a “circular water and nutrient economy.” Cultúrea will build and operate anaerobic-anoxic-oxic membrane bioreactor systems for onsite wastewater treatment and resource recovery. The proposed system consists of three parts: domestic wastewater and rainwater capture; treatment modules; and a resource reclamation system. While conventional treatment systems spend energy to oxidize nutrients only to release them to the environment, Cultúrea’s system produces bioenergy used for heating, cooking and power, reusable water free from pathogen risks, and high-quality phosphorus-enriched agricultural soil amendment to return nutrition to depleted soils. Further, Cultúrea’s system is highly efficient and modular, resulting in feasible implementation in commercial buildings, apartment complexes, schools and other facilities.

River Recon Left to Right: Matthew Falcone, Kaylyn Sinisgalli, Erin Kowalsky, and Timothy Purvis Plastic waste breaks up into microscopic pieces that are harmful to both the environment and human health. The River Recon team set out to create a detection device because there are currently no effective methods for quantifying microplastics in water—making it difficult to understand the full extent of this emerging environmental contaminant. Extensive physical sampling, preparation, and analysis can take days to generate useful data, while expensive laboratory equipment and specialized services limit the capacity to analyze environmental microplastics. To overcome these barriers, River Recon designed a sensor to swiftly, inexpensively, and efficiently identify microplastics in continuous streams of water. The sensing device works by using fluorescence, and in some cases light distortion, of plastic polymers at certain wavelengths to distinguish microplastics from soils and other interferences in water. The device works by passing water samples into a light-tight testing chamber, where it is stored in a glass tube. Light sources of different wavelengths turn on and off sequentially, and a camera takes an image of the sample’s response to each wavelength of light. The images are compiled and passed into a machine learning algorithm, which predicts which regions contain microplastics. 18

Planting Seeds for Success The Entrepreneurial Impact Competition was made possible thanks to two generous donors. Their endowed gifts provided the $5,000 prizes for this year’s winning teams and will allow CEE students to pursue their entrepreneurial goals for years to come. Learn more about the people behind the Higginbotham Entrepreneurial Prize and the Zeitlin Innovation Prize:

Bill Higginbotham

Bill Higginbotham, CE 76, is a lifelong entrepreneur. He first combined his love of engineering and entrepreneurship at Georgia Tech, where he started a thermal solar system design and construction corporation a year before he graduated. He went on to start 13 businesses in geotechnical consulting, energy and environmental management, construction, and venture capital, including ET Environmental Corporation, where he serves as president and CEO. Higginbotham said the two mandatory business classes he took in the School of Civil and Environmental Engineering provided an important foundation for his success as a businessman. As

The Zeitlin Family

Georgia Tech has always been special to the Zeitlin family. So it seemed fitting to Gregg Zeitlin to honor his mother and late father’s legacy at the school that had such a profound impact on their lives. Alan G. Zeitlin’s time and education at Georgia Tech was a transformational period in his life. Not only did it prepare him for his future career, but it presented the fortuitous opportunity to meet his future wife, Phyllis C. Zeitlin. They married and settled down in Atlanta to raise their four children shortly after Alan graduated from Georgia Tech in 1962. Alan Zeitlin went on to a successful career as an entrepreneur in construction and real estate, working closely with Phyllis Zeitlin to run their businesses. Gregg Zeitlin grew up in the family business, spending time with his parents in the 19

an alumnus, he’s giving back to the school by making sure that current students not only get a top-notch engineering education, but graduate prepared to run successful businesses of their own. Through his service on the External Advisory Board and beyond, Higginbotham has taken an active role in helping the School boost its resources for innovation and entrepreneurship. Starting in January 2020, Higginbotham became a co-instructor for a new course called Innovation & Entrepreneurship in Civil Engineering Systems. With the Higginbotham Entrepreneurial Prize, Higginbotham hopes to encourage students to take their CEE skills outside of the classroom and see what it takes to bring their ideas to life. “I wanted to do something direct and tangible,” Higginbotham said. “We need an economic incentive at the undergraduate level to drive this home.”

Gregg Zeitlin went on to pursue a degree in business, but he was always inspired by his father’s self-reliance and ability to solve problems—skills he attributes to his Georgia Tech education. With the creation of the Zeitlin Innovation Prize, Gregg Zeitlin feels he is able to honor his parents’ legacy while providing students with opportunities to take risks and try things that could ultimately help improve the human condition. “It’s experiential learning and so additive to what students are learning at school. You’re working with people, you’re experiencing losses, you’re experiencing wins,” Gregg Zeitlin said. “Even if they don’t go on to be entrepreneurs, those experiences are applicable to almost anything. It’s such a strong foundation for so many things.”

CREATING THE NEXT Over the past year, CEE faculty have received millions in grant funding for research that expands our knowledge and helps to blaze a trail for what comes next in energy infrastructure, transportation, air quality and more. Read on to learn about some of the incredible research that’s taking place here in CEEatGT.

ssistant Professor Jennifer Kaiser received an award from NASA’s New Investigator Program in support of her research on air quality. The project, entitled “Tracking Formaldehyde Production in an Urban Outflow,” involves building a ground-based formaldehyde and nitrogen dioxide monitoring network in the Atlanta metro area. The project received around $400,000 in funding from NASA and will be conducted over three years. Kaiser will use observations from the monitoring network to understand how satellite-based air quality observations— which measure the total amount of pollution integrated from the ground to the top of the atmosphere—are related to pollutant concentrations at nose-level. The ultimate goal is to combine measurements from the ground and satellites to better understand the spatial and temporal variation in air pollution across urban-rural gradients. “Because Atlanta has high levels of both anthropogenic and biogenic emissions, it is a particularly useful environment for testing our understanding of atmospheric composition,” Kaiser said. “Satellite-based observations have improved dramatically in the past few years, and the planned launch of new high-resolution satellites in 2022 will give us a wealth of new information. Now we’ll have the matching field measurements in Atlanta to build an even more complete picture.” NASA’s New Investigator Program in Earth Science is designed to support outstanding scientific research and career development of scientists and engineers at the early stage of their professional careers. The program welcomes innovative research initiatives and seeks to cultivate diverse scientific leadership in Earth system science. The Earth Science Division places particular emphasis on the investigators’ ability to promote and increase the use of space-based remote sensing through the proposed research.

Researchers Improve Transportation Accessibility and Efficiency

n February 2021, The Atlanta Regional Commission received the first phase of a $9.3 million contract from the U.S. Department of Transportation to develop a “Complete Trip-ITS4US” project designed to improve transportation for older adults and people with disabilities. Professor Randall Guensler and Senior Research Engineer Angshuman Guin are the principal investigators leading the research from Georgia Tech’s School of Civil and Environmental Engineering. Other project partners include the Atlanta-region Transit Link Authority, Georgia Department of Transportation, GO Systems and Solutions, Gwinnett County, IBI Group, Kimley-Horn, and Statewide Independent Living Council of Georgia. The Complete Trip project leverages the latest in transportation technology, such as connected vehicles, ‘smart’ traffic lights, and trip navigation tools to provide an improved travel experience that increases independence and autonomy for older adults and people with disabilities. The project will provide detailed information and step-by-step navigation tailored for users’ specific needs, along with a range of other features designed to improve trip efficiency and safety. The pilot project, which will be developed over the next two years, will focus on residents in Gwinnett County with plans to eventually roll out nationwide.

Program features include: • A connected mobility platform equipped with realtime network information that suggests route changes throughout the user’s trip and updates conditions with crowd-sourced tools • Integration with connected vehicle infrastructure to hold pedestrian signals longer and alert drivers to their presence • A mobile app, available in multiple languages, that helps travelers safely cross intersections, request transit connections, and identify safe boarding locations • Wayfinding and navigation that incorporates all walking paths, providing more reliable connections • A prioritization system that gives buses running behind schedule higher priority when a vulnerable road user is on the bus or waiting at a stop • Routes that account for sidewalk conditions so that route recommendations are tailored to each user’s specific needs. The project takes advantage of Georgia Tech’s extensive previous research on Sidewalks and a comprehensive traffic network analysis platform developed by the Georgia Tech team referred to as the Space-Time-Memory (STM). The STM integrates information such as real time traffic status as well as short and long term archival data on traffic, network link impedances, etc. with pedestrian, bicyclist and transit simulation tools. The STM will serve as the core information broker in the system developed in the Complete Trip project.

Project Treats Wastewater to Grow Produce on Campus

very day, an estimated 34 billion gallons of wastewater is processed in treatment facilities across the country, according to the EPA. Now, some of that wastewater will be treated right on campus next to the Center Street Apartments and eventually used to grow fresh produce. In 2018, Yongsheng Chen, professor in the School of Civil and Environmental Engineering, and his research team received a $5 million grant from the USDA to create a pilot project for wastewater treatment. The most recent progression of Chen’s pilot project is the implementation of two shipping containers on campus. One will act as a wastewater treatment facility, and the second will host a mini-farm that the team will use to grow lettuce with the newly treated water. For now, the lettuce will be discarded, but the team aims to eventually grow produce that is up to FDA standards for consumption. Abigail Cohen, an environmental engineering Ph.D. student on Chen’s team, explained that the new treatment facility and mini-farm are bringing the team closer to their ultimate goal. “We want to move away from conventional fertilizer inputs for agriculture and wastewater treatment, as well as reduce the amount of energy and environmental impact that goes into farming and create a more circular sanitation food process,” said Cohen. Currently, conventional wastewater treatments use the method of aerobic digestion, meaning that large amounts of air are pumped into big water tanks to push out the solids and organic matter in the water. This aerobic method not only requires high amounts of energy, but it also creates large amounts of sludge that often end up in landfills. In comparison, Chen’s team plans on using an anaerobic membrane biological treatment to break down the organic matter in wastewater. The amount of biomass that is generated from an anaerobic digestion process is 90 percent less than aerobic, meaning it will result in a smaller footprint in waste generation. — By Janat Batra

Research Lays Foundation for Partial Cloaking of Holes in Elastic Plates from Stress Waves

n their latest research into the feasibility of cloaking, Professor Arash Yavari and Ashkan Golgoon, PhD CE 20, found that while it’s not possible to fully protect plates from stress waves, a partial protection—or cloaking— is possible. “Our conclusion is that you cannot have exact cloaking, but you can have hope for partial cloaking,” Yavari said. “This is a mathematical foundation for the future design of approximate cloaks or shields.” The paper, “Transformation Cloaking in Elastic Plates,” published in the Journal of Nonlinear Science in January, is the culmination of four years of research backed by the U.S. Army Development Command, known as DEVCOM, Army Research Laboratory. Yavari and his former student Golgoon began this foundational research to find out if the idea of cloaking – giving structures a protection that would render them “untouchable” to stress waves like blasts or earthquakes—is even possible. The Army Research Lab took an interest in the work because of its potential applications for defense. If the researchers found cloaking to be possible, it could be incredibly useful to protect personnel, vehicles, and sensitive facilities under threat of attack. Yavari and Golgoon started their four-year,

federally-funded project in 2018 to lay the mathematical foundations for cloaking technology and explore if it’s theoretically possible while still respecting the laws of physics. In a 2019 study published in the journal Archive for Rational Mechanics and Analysis, the authors concluded that it’s not possible to perfectly steer stress waves in the ground, like those emanating from a blast, around objects like buildings. Despite casting doubt on dozens of theoretical papers on “elastodynamic cloaking”, Yavari and Golgoon concluded that engineers shouldn’t completely give up on it — just on the idea of an ideal cloak. Limited cloaking could still add a degree of protection to structures, particularly against some stress waves common in earthquakes. In their most recent paper, Yavari and Golgoon shifted their focus to two-dimensional structures by analyzing the possibility of ideal cloaking in elastic plates. Their conclusion was again a “no-go theorem”: Exact cloaking isn’t possible, but partial cloaking is and could still be very beneficial. “It is still very positive because you know what you can expect and what you cannot expect,” Yavari said. “You can’t hide something from an arbitrary wave. But if you know what your service loads are, you could design an approximate cloak.”

Shuttering Fossil Fuel Power Plants May Cost Less Than Expected

ecarbonizing U.S. electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A generator-level model described in the Dec. 4, 2020 issue of the journal Science suggests that most fossil fuel power plants could complete normal lifespans and still close by 2035 because so many facilities are nearing the end of their operational lives. Meeting a 2035 deadline for decarbonizing U.S. electricity production, as proposed by the presidential administration, would eliminate just 15% of the capacity-years left in plants powered by fossil fuels, says the article by Emily Grubert, an assistant professor in Georgia Tech’s School of Civil and Environmental Engineering. Plant retirements are already underway, with 126 gigawatts of fossil generator capacity taken out of production between 2009 and 2018. “Creating an electricity system that does not contribute to climate change is actually two processes — building carbonfree infrastructure like solar plants, and closing carbon-based infrastructure like coal plants,” Grubert said. “My work shows that because a lot of U.S. fossil fuel plants are already pretty old, the target of decarbonization by 2035 would not require us to shut most of these plants down earlier than their typical lifespans.” Of U.S. fossil fuel-fired generation capacity, 73% (630 out of 840 gigawatts) will reach the end of its typical lifespan by 2035; that percentage would reach 96% by 2050, she says in the Policy Forum article published in Science. About 13% of U.S. fossil fuel-fired generation capacity (110 gigawatts) operating in 2018 had already exceeded its typical lifespan. Because typical lifespans are averages, some generators operate for longer than expected. Allowing facilities to run until they retire is thus likely insufficient for a 2035 decarbonization deadline, the article notes. Closure deadlines that strand assets relative to reasonable lifespan expectations, however, could create financial liability for debts and other costs. The research found that a 2035 deadline for completely retiring fossil fuel-based electricity generators would only strand about 15% (1,700 gigawatt-years) of capacity life, along with about 20% (380,000 job-years) of direct power plant and fuel extraction jobs that existed in 2018. “Closing large industrial facilities like power plants can be really disruptive for the people who work there and live in the surrounding communities,” Grubert said. “We don’t want to repeat the damage we saw with the collapse of the steel industry in the 1970s and ’80s, where people lost jobs, pensions, and stability without warning. We already know where the plants are, and who might be affected. Using the 2035 decarbonization deadline to guide explicit, community grounded planning for what to do next can help, even without a lot of financial support.” — By John Toon

Tech Team Wins $1 Million Grant to Lead University Transportation Center

team of Georgia Tech researchers has been awarded a $1 million grant from the U.S. Department of Transportation to address declining transit ridership. The grant establishes a Georgia Tech-led team as one of four new Tier 1 University Transportation Centers (UTCs), which are funded to address critical transportation challenges facing the United States. Just four teams were selected from nearly 70 applications to receive the UTC grants. Georgia Tech is leading a research consortium as part of the University Transportation Center they’ve named T-SCORE: Transit Serving Communities Optimally, Responsively, and Efficiently. The team is directed by Kari Watkins, the Frederick Law Olmsted Associate Professor in the School of Civil and Environmental Engineering, and includes fellow civil engineering professors Michael Hunter and Srinivas Peeta, along with industrial and systems engineering Professor Pascal Van Hentenryck. The Georgia Tech researchers are joined by partners from the University of Tennessee, the University of Kentucky and Brigham Young University. Through a project sponsored by the Transportation Research Board, the team has already spent two years studying the underlying factors that have led to a recent decline in transit use. In 2018, bus ridership in the United States was down 12 percent from its 2012 peak and rail ridership had declined 4 percent from its 2014 peak. This surprising drop came amid both transit service expansion and economic growth, leaving researchers to search for explanations. The T-SCORE Center plans to continue this research as well as focus on solutions. The goal is to guide public transportation into a sustainable and resilient future while equipping local planners with the tools needed to enact their strategic visions into communities. Those strategic visions could include a focus on serving riders who depend on transit the most, consolidating services to highridership corridors with high levels of congestion, integrating ondemand transit that looks more like services such as Uber, or using pricing and incentives to make it easier for transit to compete with other modes of transportation. The researchers are planning a two-track research approach. The Community Analysis Track will further assess ridership trends, identify and measure the markets most effectively served by transit, and assess transit’s ability to respond to a changing environment. The Multi-Modal Optimization and Simulation Track builds upon previous research to allocate which services should be traditional transit routes with a set schedule and which services should be flexible on-demand. This will consider competition from ride-hailing services like Uber and Lyft, which are a key contributor to declining transit ridership.

Researchers Partner with GDOT to Develop Advanced Transportation Technology

Photo courtesy of WABE Atlanta

n early 2021, the Georgia Department of Transportation (GDOT) received a $3.2 million Advanced Transportation and Congestion Management Technologies Deployment grant from the Federal Highway Administration. Senior Research Engineer Angshuman Guin and Professor Michael Hunter from Georgia Tech’s School of Civil and Environmental Engineering are partnering with the agency on the project, entitled “Emergency Vehicle Preemption Using Connected Vehicle Technology.” The project is one of 10 nationwide selected for the grants based on its use of advanced intelligent transportation systems technologies that will improve mobility and safety and support vehicle connectivity. The grant will be used to deploy vehicle-toinfrastructure applications to provide coordinated, corridor-based signal timing preemption for emergency vehicles. A first in connected vehicle deployments, a roadside unit-to-roadside unit application will establish communications between intersections to implement a traffic queue flush plan. A flush plan identifies the downstream intersections that may need to be cleared of congestion and provides dedicated green phases to allow emergency vehicles to move efficiently and safely to their destination. This proposed project will provide the required roadside infrastructure and in-vehicle devices to support this connected vehicle deployment. With these systems, field equipment will support vehicle to

infrastructure data exchange with emergency vehicles including Highway Emergency Response Operator (HERO) and the Metro Atlanta Ambulance Service. Signal preemption will reduce emergency vehicle travel times, saving precious seconds in responding to incidents and returning to hospitals, ultimately saving lives. GDOT has partnered with Georgia Tech to develop methodologies for the processing and analysis of connected vehicle and other data in real-time to support advanced preemption control strategies. The Georgia Tech team is at the forefront of research in Digital Twin development, a real-time data driven traffic simulation that provides a virtual representation of corridor operations to aid in decision making. Georgia Tech will create a digital twin of the connected corridor enabling real-time performance monitoring and will develop, test, implement, and evaluate forward-looking performance metrics enabling optimal emergency vehicle preemption strategies. Georgia Tech will assist GDOT with evaluating the deployed solution’s effectiveness to meet stakeholder requirements and operational objectives. Georgia Tech will be conducting both pre and post analysis of the proposed system to evaluate its effectiveness focusing on reduced incident response timelines and safety. The modeling application will utilize an innovative evaluation approach through real time connected vehicle data.

Marine Animals Inspire New Approaches to Structural Topology A

mollusk and shrimp are two unlikely marine animals that are playing a very important role in engineering. The bodies of both animals illustrate how natural features, like the structures of their bones and shells, can be borrowed to enhance the performance of engineered structures and materials, like bridges and airplanes. This phenomenon, known as biomimetics, is helping advance structural topology research, where the microscale features found in natural systems are being mimicked. In a paper published by researchers at the Georgia Institute of Technology and the Pontifical Catholic University of Rio de Janeiro (Brazil), a new approach to structural topology optimization is outlined that unifies both design and manufacturing to create novel microstructures, with potential applications ranging from enhanced facial implants for cranial reconstruction to improved ways to get materials into space for planetary exploration. “With traditional structural topology optimization, we use algorithms to determine the ideal layout of a structure – one that maximizes structural efficiency and requires fewer material resources,” said Emily Sanders, a Ph.D. student in the School of Civil and Environmental Engineering at Georgia Tech, and

co-author of the paper. “Our new research takes that a step further by introducing structural hierarchy, microarchitectures, and spatially-varying mechanical properties to enable different types of functionality like those observed in the cuttlefish and mantis shrimp.” The properties of both animals inspired the new framework for designing hierarchical, spatially-varying microstructures and required the researchers to build on existing technologies used to create 3D-printed structures. “In our recent work, we’ve developed technology that includes new algorithms and computations that are the enablers of a hierarchical microstructure,” said Professor Glaucio Paulino, co-author of the paper. “We can then input that information into 3D printers and create structures with tremendous amounts of details. After studying the porous, layered cuttlefish bone that has extremely adaptive properties, we’ve been able to apply that to new structures and materials like the ones shown in our paper.” Paulino and his team hope this new research will be applied to his earlier work in cranial reconstruction on cancer patients to help those who have had massive facial injuries and bone loss. — By Georgia Parmelee 28

rofessor Glaucio Paulino has been elected to the National Academy of Engineering (NAE), one of the highest professional distinctions awarded to an engineer. Paulino, the Raymond Allen Jones Chair in the School of Civil and Environmental Engineering, was selected for the honor “for contributions to topology optimization and its applications to medicine and engineering.” “Getting elected to NAE was such a great blessing and amazing surprise,” Paulino said. “The idea of becoming an NAE member was always a dream, however, today the dream turned into reality. I am humbled by this recognition and honored to join such a group of distinct colleagues from academia and industry.” Paulino, along with Mechanical Engineering Professor Andrés García and alumni Christopher Jones, PhD AE 86, and Roger Krone, AE 78, represent Georgia Tech among 103 new members and 23 international members. “I’d like to extend my deepest congratulations to our College faculty members Andrés García and Glaucio Paulino on their induction into the National Academy of Engineering,” said Raheem Beyah,

dean and Southern Company chair of the College of Engineering at Georgia Tech. “Their forward-thinking research in molecular engineering and topology optimization, respectively, is making an indelible mark on the future of engineering specific to medicine. This is a proud moment for the College, and I look forward to the advances they will make in their fields and the impact that will have on our nation.” Election to the National Academy of Engineering is among the highest professional distinctions accorded to an engineer. Academy membership honors those who have made outstanding contributions to “engineering research, practice, or education, including, where appropriate, significant contributions to the engineering literature” and to “the pioneering of new and developing fields of technology, making major advancements in traditional fields of engineering, or developing/implementing innovative approaches to engineering education.” Paulino is world-renowned for his contributions to topology optimization and applied mechanics. He created the first stable formulations of topology optimization using polygonal and mimetic-based virtual elements, including deep-learning enhanced multi-resolution and multiscale approaches connected to additive manufacturing processes that have been widely used. He was one of the early investigators to apply topology optimization to the medical field by designing patient-specific large craniofacial segmental bone replacements to help cancer patients and those with massive facial injuries and bone loss. Paulino’s methods for topology optimization have been employed by industry, academia and national labs. For instance, his design-update methods have been incorporated into the PLATO software developed by SANDIA National Laboratories by adding capabilities to multi-material topology optimization, and stress constraints. These capabilities have been used by SANDIA to design mission-critical parts in classified and defense projects. Paulino has also worked with SIEMENS to create a deep-learning enhanced topology optimization approach through an online training concept employing machine learning to extract the underlying mapping between design variables and their sensitivities, leading to a universal machine learning approach for topology optimization. Several joint patents and papers have resulted from this effort.

Kenneth Hyatt Distinguished Sire Shares Learnings from Career Journey S

tacy Sire, CE 96, loves her job as director of structures engineering at Boeing Commercial Airplanes. Over 23 years, she has risen through the ranks at Boeing Commercial Airplanes and achieved a lot as both an engineer and an executive. But she’s quick to credit her mentors, role models, peers and professors for helping her succeed along the way. During the Fall 2020 Kenneth Hyatt Distinguished Leadership Speaker Series on Sept. 17, Sire shared advice and anecdotes from her career journey with a virtual Georgia Tech audience. Sire said that cultivating a strong professional network begins with friends and teachers. “I wouldn’t have my job at Boeing without one of my professors,” Sire said. “Just know that those relationships and that network that you’re building right now will be super important throughout your career.” Sire said in high school, she didn’t know much about engineering at all until a friend’s father, who worked as a civil engineer, answered her questions and supported her interest in the profession. “It was through conversations with him about his work that I realized engineering was something I was very passionate about,” Sire said. “I always thank him and give him credit for inspiring me to go into engineering.” After earning her degree in civil engineering at Georgia Tech, Sire set her sights on a career in structures engineering and accepted a position at Boeing Commercial Airplanes. Sire began her tenure at Boeing as a design engineer on 777 fuselage structure. She spent

time as a stress analyst in interiors supporting all Boeing Commercial Airplane models. As a senior manager, Sire led the 787 systems stress team through 787-8 certification/ delivery and then created and led the 787 Airplane Integration Office. Sire said one of the pinnacles of her career was riding in the flight deck aboard the 787-8 flight test. “At one point this airplane was just an idea,” Sire said. “It was just amazing that I was in this physical machine that had come from an idea and some crude engineering that evolved into something so amazing.” Over the years, Sire has continued her education. She earned a master’s in mechanical engineering and a master’s in business administration from the University of Washington. She also earned a certificate from UW for Aerospace Industry Manufacturing Seminar and one from Harvard Business School for completion of the Advanced Management Program. Sire told the audience that she strongly encourages lifelong learning. It’s important, she said, to be exposed to new people and new ideas to continue to grow and succeed in your career. “I encourage you to stay humble. When you’re humble, you’re more curious. You want to be confident but not arrogant. When people get arrogant, they get less curious and they don’t learn and grow,” Sire said.

Leadership Speaker Series DesRoches Shares the 10 C’s of Academic Leadership I

n more than 30 years in academia, Reginald DesRoches has learned a lot about leadership. DesRoches is the provost of Rice University, but he’s no stranger to CEEatGT. He spent nearly two decades as a member of the faculty and served as the Karen and John Huff School Chair until 2017. As the Spring 2021 speaker for the Kenneth Hyatt Distinguished Leadership Speakers Series, DesRoches shared his life story and career journey into academic leadership with a virtual Georgia Tech audience on Feb. 23. Based on his experiences, DesRoches distilled his advice for leaders into 10 “C’s” of Academic Leadership: 1. Being Connected and Making Connections: Building relationships and trust are essential to being a leader. 2. Communication: While Covid-19 has limited our ability to interact, DesRoches believes it’s important to find ways to safely connect with each other in person. 3. Collaboration: Especially in academia, people are divided into groups—schools within colleges, affinity groups within schools, and so on. “As a leader it’s important to bring people together and foster collaborations across disparate disciplines,” DesRoches said. 4. Community Builder: Work hard to build a community of people who enjoy working together and being part of a team. In addition to talent, it is critical to look for people who can contribute to a positive environment. 5. Agent of Change: As a leader, you will be hired to make changes in an organization. “You also have to constantly question how you’re doing things

yourself,” DesRoches said. “The worst thing you can do as an organization is remain stagnant.” 6. Courage: In 2010, he was asked to travel to Haiti as part of the U.S. earthquake response team. “There were health hazards, security hazards, we didn’t know where we would stay,” DesRoches said. “But I took a risk…it was one of the greatest things I’ve done in my career.” 7. Stick to your Core values: As a leader, you will have to make many difficult decisions. Act with purpose and meaning to ensure your decisions align with your values and your mission. 8. A Champion for others: Faculty members are focused on competing for grants, awards and recognition. But as a leader, it’s important to put your own interests aside to be a champion for the people on your team. 9. Consultative leadership: Engage a broad group of people in the decision-making process. You will learn from people who push back, and may discover there are consequences of your decisions you hadn’t considered. 10. Use Carrots more than sticks: You can accomplish your goals using “carrots,” —that is, positive reinforcement—a majority of the time. “It’s more effective, and people will appreciate it more,” he said. 40
