Letter from the Chair of the Civil Engineering Institute Dear members and friends of the Civil Engineering Institute (CEI), The CEI Board of Directors continues to support and advance the mission of the Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering (CEIE). On behalf of the board, I am presenting a series of accomplishments that we achieved during the challenging year of 2020. After the world entered a deadly pandemic, our activities within and outside Mason continued, mostly virtually.

On February 5, we hosted our last in-person event before the pandemic lockdown. This membership event was hosted at the Science and Technology Campus, and the Virginia Department of Transportation’s Northern Virginia District Administrator Helen Cuervo and the Northern Virginia District Environmental Compliance team presented information on environmental needs and compliance in the area.

We recruited two new members for the institute and are looking for more members. There are many benefits to being part of CEI. Our members have access to cutting-edge research and technology developed by the faculty, get opportunities to share their knowledge of industry through classroom presentations, and can collaborate with talented faculty on projects.

Our directors support the department in various capacities: • bringing our knowledge of the industry to future engineers as adjunct professors and guest speakers;

At the March board meeting, we reviewed the latest technology for virtual meetings and continued supporting the university via cloud-based video conferencing during the pandemic.

• advancing the CEI board’s mission as committee members;

We held our first virtual annual luncheon in September 2020 and selected the year’s engineering excellence and leadership award winner–Paul J. Wiedefeld, general manager and CEO of Washington Metropolitan Area Transit Authority. He will receive the award during this Spring’s Annual Luncheon, on March 25, 2021 being held virtually. This award is presented in recognition of Exceptional Leadership, Outstanding Lifetime Achievement, and significant contribution to the profession of civil engineering.

• working with the faculty to weave the materials taught in the undergraduate courses with the skills required to successfully integrate new graduates in industry.

We continued to support the American Society of Civil Engineers (ASCE) concrete canoe and steel bridge activities conducted during the 2

pandemic and provided necessary funding for the innovative projects of the Engineers for International Development (EfID). It’s encouraging that the students, while observing all safety regulations, continued to employ their innovative thinking in solving engineering problems outside the classroom.

• supporting the department chair’s new academic initiative in creating a Construction Management Program;

The board of directors invites you to read the 2020 Annual Report to discover more about the department’s accomplishments.

Our diverse membership will continue its mission to serve George Mason University students and faculty. g Sincerely, Cerasela M. Cristei, PhD, PE Chair, Civil Engineering Institute

Message from the Chair of the Sid and Reva Dewberry

Department of Civil, Environmental, and Infrastructure Engineering Dear alumni and friends, For all of us, 2020 was a year to remember, reflect upon, and learn from. Although the year was full of challenges due to the global pandemic, the Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering (CEIE) succeeded in adapting and adjusting without compromising the quality of our teaching, research, and service. I am deeply thankful to our faculty and staff for their dedication and hard work, to our students for their patience and understanding, and to our CEI and Advisory Board members for their continued support. I am proud of our success in overcoming so many obstacles, rising to the challenges, and experiencing another productive and successful year.

Our challenges included finding a way to provide our students with lab and hands-on learning experience without compromising their health and safety or quality of education, maintaining our research growth momentum, as well as continuing valuable student organizations engagement and activities. Our faculty was so innovative in adapting to and excelling in offering their classes and labs online and hybrid in a very short time.

On the research side, our research productivity and funding continued to grow substantially. In fact, during 2020 our research expenditures rose by more than 26 percent from 2019 to $2.4 million.

We recruited and hired two outstanding new faculty from Stanford and Harvard universities in the important research areas of water quality, air quality, and public health and Ken Walsh who has a background in construction engineering and serves as the chief of staff for our new university president joined our ranks.

I am especially proud of our students’ accomplishments at the state and national level. In 2020, our Engineers for International Development participated in the American Water Works Association annual conference. Nearly 2,000 water and wastewater professionals attended this virtual event, and three sponsor-provided competitions were heavily attended by many universities. Our students competed in all three competitions, Digital Knowledge, Poster, and the 17th Annual AWWA Student Water Challenge and won first place in all three events. No university has ever completed this hat-trick. I am also proud of our Construction Management Association of America student chapter, which won two national scholarships in its first year of existence.

These are only a few of the year’s highlights. I invite you to read this 2020 annual report to learn more about our students and faculty accomplishments during last year. g With my best wishes for safe and healthy years ahead of you, Sam Salem, PhD, PE, CPC, LEED AP Dewberry Professor and Department Chair Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering

Improving Stormwater Infrastructure in Northern Virginia

M

ason Engineering researchers are studying ways to shore up the stormwater infrastructure in Northern Virginia to protect the region against flooding in the future.

The area is growing fast in terms of urbanization and population, and it’s near the Potomac River and the Chesapeake Bay, which makes it vulnerable to flooding, says Civil Engineering Associate Professor Viviana Maggioni.

“

We are looking at how the precipitation is going to change in the next 30 to 50 years and what parts of the area are vulnerable to flooding.

”

Stormwater infrastructure is critical for carrying water through an urban area during extreme precipitation events. It includes curbs, gutters, drains, piping, and collection systems such as basins and reservoirs.

“

We are developing insights to help decisionmakers build resilient stormwater infrastructure that is still safe under future conditions.

”

“The designs for those systems are usually based on historical climate conditions, but we can’t just rely on the past to design stormwater infrastructure anymore because climate variability may be affecting the desired performance of this infrastructure in the future,” says Associate Professor Celso Ferreira.

Maggioni, Ferreira and two of their PhD students, as well as several other Mason researchers and regional experts, got involved in the American Geophysical Union (AGU) Thriving Earth Exchange project, initiated by the Northern Virginia Regional Commission (NVRC), which

Leading Fight for a Sustainable Future

M

ason Engineering senior and civil and infrastructure engineering major Jon Parker is adding his voice to the climate change cause, urging people to look close to home and make changes in their own lifestyles to help protect our planet.

“There are so many easy things people could do if they just knew about it,” he says. “There are so many things, like reducing meat, or changing some products you use, that can help in the long run,” he says.

In his own life, Parker stopped consuming meat a couple of years ago because of the environmental impact. “Meat production contributes to deforestation. It requires a large amount of water and a lot of crops grown in the United States go directly to feeding cattle,” says Parker.

His interest in the environment was triggered when he watched the documentary Before the Flood, and after that, he dove

deeper into how our everyday lives affect the environment. “The documentary was what opened my eyes, and the more I learned, the more I cared,” says Parker.

A transfer from Northern Virginia Community College, Jon Parker decided to major in civil and infrastructure engineering because of the connection to environmental engineering. He also quickly got involved with student groups once arriving at Mason.

Currently, he serves as student chapter president of Engineers for International Development (EfID), which has taken several trips to a village in Ecuador to build a water distribution system. “EfID focuses on helping people and providing a better life for them. That is what sparked my interest in it when I came to Mason. I want to leave the world better than I found it,” says Parker.

While EfID didn’t take their typical trip this January to Ecuador, Parker and the rest of the executive board are working on coordinating safe, socially distanced events like tree planting at local schools.

After Mason, Parker plans on pursuing his master’s degree in environmental engineering to continue following his passion.

“I eventually want to start my own company to help corporations abide by government regulations on the environment,” he says. He also hopes to have a sector that fights for legislation that protects the environment.

“There’s a lot of regulation that needs to be implemented to put us on the right track to protect our planet,” says Parker. “We only get one of these, one planet, and it is extremely important that we protect it for the next generation.” g

even though we may just call them clays or sands. Therefore, students need to have hands-on experience in our laboratory that would not be possible to achieve through virtual learning.”

In the three-credit graduate course, Sources of Geotechnical Data, students get direct experience in quantifying and assessing the properties of soils with a series of handson laboratory tests throughout the semester. The properties of the soils, obtained from the tests conducted in this course, are key factors in designing engineered infrastructures such as foundations, embankments, and earth-retaining structures, as well as assessing the stability of slopes, Tanyu says.

To help the class run smoothly and efficiently, Tanyu taught the course with co-instructor Aiyoub Abbaspour. Abbaspour has taken this class from Tanyu in the past, which created a unique opportunity as both instructors were very familiar with the content and the way to handle conducting the experiments in the laboratory.

“Soils are produced from the weathering of rocks based on the geological processes that take place over a long time,” Tanyu says. “No soil type is the same,

In this course, students had the opportunity to be in the laboratory every week.

They divided the 12 students into groups. While one group learned the background and theory associated with a specific test, another group watched how to set up the tests demonstrated by the instructor via a projector and then implemented their learning by conducting the tests one by one as they rotated in the laboratory. Once the test results became available, the rotations also included a group of students discussing their findings and the interpretation of the data.

While in the laboratory, each student stood at designated spaces that are marked on the floors with an X. The three workstations were sanitized with alcohol between students’ rotations. While in the lecture hall, students sat at least six feet apart from each other.

The plan paid off.

Tanyu says, The students completed the class without getting COVID-19. I am very grateful to the students for following the mask and hygiene rules while still being engaged and interactive.

“

”

“Splitting the teaching responsibilities for the course with my post-doc Aiyoub Abbaspour gave significant hands-on time for the students to complete many complex tests in our laboratory and then have the opportunity to discuss their results and observation without rushing.

I hope we have the opportunity to teach this class with two instructors in the future.” g

improving health

Assistant Professor Lucas Henneman is studying the impact of air pollution on health.

E

nvironmental researcher Lucas Henneman is investigating air pollution’s impact on health.

He uses large datasets and computer models to track pollution after it’s emitted from sources such as automobiles, coal power plants, and natural gas plants. The models help identify which people in nearby communities breathe in pollution.

“Each source leaves its air pollution fingerprint on the surrounding area, and we use those fingerprints to study how each source has impacted air quality over time and how that has affected people’s health,” says Henneman, an assistant professor in the Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering (CEIE). His research is funded by the United States Environmental Protection Agency and the non-profit Health Effects Institute.

He has found that emission reductions from power plants and automobiles over the last 20 years have reduced the incidence of some health problems including cardiovascular and respiratory conditions.

Investigating Air Pollution’s Impact on Health Overall, the air quality is better in the United States now than it was 10, 20, and 50 years ago, he says. “I like that my research starts with a success story. We’ve made impressive strides to clean our air, but there’s more work to be done to keep people healthy.”

“

Each source leaves its air pollution fingerprint on the surrounding area, and we use those fingerprints to study how each source has impacted air quality over time and how that has affected people’s health.

”

Some estimates suggest that more than 100,000 Americans die each year from illnesses caused by air pollution, Henneman says.

“We are developing models and devising new analytical techniques to create evidence for continued improvements in environmental policy. We’re looking at where to make emissions reductions, so we get the best return on our investment moving forward.”

Henneman is also part of a group of experts looking at air pollution in China, which has made progress in recent years but still experiences unhealthy levels of air pollution, he says.

Associate Chair Laura Kosoglu, of CEIE, says, “Improving air quality is one of those goals where it’s not a question of if we should do it. The question is how to improve air quality efficiently and effectively, and Lucas’s research directly considers the impacts on public health. We are excited to have Lucas join our department.” g

change the world Chief of Staff and civil engineer Ken Walsh says he’s impressed with the strength and resilience of the Mason community.

M

ason Presidential Chief of Staff Ken Walsh is about building bridges.

The story of the Brooklyn Bridge inspired him as a freshman engineering student, work on the soil for a bridge over the Salt River near Tempe, Arizona, kept him in graduate school, and his work in higher education has built bridges for students and communities around the world.

“When I started my engineering studies at Arizona State University, I joined the student chapter of the American Society of Civil Engineers (ASCE),” says Walsh. “All new members received a copy of David McCullough’s book, The Great Bridge.”

Being a history buff, he read the book in a weekend and it changed the way he thought about engineering.

“After reading the book, I realized that changes to the built environment can change the world. The people who built that bridge made history,” he says.

“The idea that I could be a part of history through engineering practice inspired me.”

Chief of Staff and Civil Engineer Ken Walsh Brings Diverse Background to His Job After graduating with his degree in civil engineering, Walsh got a job with a local company and worked on projects around Phoenix. “I loved driving around town and seeing the finished buildings that we had constructed,” he says. Walsh started taking night classes and says that he planned to take courses to improve his engineering practice.

But another bridge, this one closer to home in Tempe, across the Salt River, led him to pursue his PhD. “During graduate school, I ended up working on a soil investigation project related to a freeway bridge over the Salt River. The soils exhibited unusual behaviors and while I was studying them my advisor asked me to apply for a National Science Foundation fellowship which would pay for the PhD,” says Walsh.

While in graduate school, Walsh continued working, but the small family-owned business that he had been working for changed ownership and the culture changed. This led him to look for a change of his own.

Walsh saw an ad for a job at Arizona State University teaching construction engineering and decided to take a chance. “At the time I didn’t see it as a long-term thing, but I stuck with it until I got tenure,” he says.

“

Teaching allowed me to be part of even more projects, and my student’s advancement and accomplishments gave me great pleasure.

”

When San Diego State University started its program in construction engineering in 2002, Walsh bridged the gap between teaching and administration. Serving as the director of the program allowed him to have an impact on more students and faculty.

For more than one hundred years, the Brooklyn Bridge has carried people from Manhattan to Brooklyn and back.

George Mason University’s Chief of Staff Ken Walsh credits the bridge with keeping him in engineering.

Building this program led to his involvement in building a new STEM-focused campus in Tbilisi, Georgia. The project involved every aspect of running a campus. His team built the program from the ground up, dealt with curriculum, accreditation, and fundraising, but Walsh says the most rewarding aspect of all was witnessing the potential transformation in people’s lives.

“I saw the power of higher education, not just STEM,” says Walsh.

After the experience in Georgia, he was looking for a place to return home to and the job working as Chief of Staff with President Gregory Washington at the Samueli School of Engineering at UC Irvine looked

32

like a good fit. When Washington moved to Mason last summer, Walsh came along to fill the position of Chief of Staff.

It’s been a challenge starting a new job with the pandemic, but Walsh says he’s impressed with the strength and resilience of the Mason community. It has a supremely balanced perspective,” says Walsh.

“Teaching, learning, and personal growth are all done here more thoughtfully.” He sees a level of understanding of the impact of higher education that you don’t see everywhere. g

teaching, learning, + personal growth

Ken Walsh, a student of history, credits his reading of David McCullough’s book The Great Bridge for sparking his interest in engineering.

translator problem-solver Water resource engineer and Mason Engineering alumna Ingrid Davis-Colato was a technical advisor to the Engineers for International Development on their trip to Ecuador before COVID-19. The group built a new clean water system for people in a small, agricultural community.

r

T

he way alumna Ingrid Davis-Colato sees it, Mason Engineering’s faculty helped her build a rewarding career as a water resource engineer. She’s determined to do the same for others.

“I want to pay back a little of what Mason gave me,” says DavisColato, BS Civil and Infrastructure Engineering ’16, MS Civil and Infrastructure Engineering ’19.

Her career journey began when she moved to the United States from El Salvador at age 19, learned to speak English, and earned associate degrees in engineering and business administration from Northern Virginia Community College.

She came to Mason unsure of the next steps on her path. “My father has a bachelor’s degree in business administration, but he told me his dream was to become an engineer because engineers are experts at problem-solving.”

That motivated her to explore engineering opportunities. When she took several water resource classes in the Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering (CEIE), she found her passion.

Civil and Infrastructure Engineering Alumna Finds Creative Ways to Give Back She works at Michael Baker International, helping construction companies, municipalities, and government agencies avoid flooding when they build roads, parking lots, or buildings. “I make sure the water that is leaving the developing site is clean, so it won’t pollute streams, rivers, or bays,” she says.

To give back to Mason, she returns every semester to do guest lectures for civil engineering classes. She also serves as a technical advisor for Mason’s Engineers for International Development.

In January of 2020, she accompanied the group to Ecuador, where they built a new clean water system for a small, poverty-stricken community.

“The students designed the whole system. I was able to be in the trenches with these students, laying pipes with them, translating between the students and the people in the community,” she says. “We provided water for a dozen houses that have never had potable water in their lives.”

”

One day, Davis-Colato would like to earn a doctorate from Mason and return as an adjunct professor. “I like teaching, but I don’t see myself leaving industry to become a full-time professor.

I want to help students in the same ways that my professors helped me.” g

Studentathlete Steps Up to the Plate to Inspire Women in STEM Taylor Dadig’s hometown of Pittsburgh, Pennsylvania, otherwise known as the “City of Bridges,” inspired her to pursue civil engineering, and now as a junior at Mason, she hopes to inspire other women to join the field.

“Bridges are all over the city, and I was always curious about how they worked,” says Dadig. “But I didn’t know there would be such a difference between the number of men and women in the field.”

Dadig, a member of Mason’s softball team, has pushed herself to excel on the field and in the classroom to show other women and girls that they can accomplish anything they set their minds to. “Women bring a new perspective to problemsolving that is important in engineering. We have different

38

experiences, different ideas, and we can do it just as well as men,” says Dadig.

At Mason, she sees the disparity in her classes. “While about half of my professors in civil engineering at Mason are women, which is inspiring, most of my classmates are still men,” she says.

For the past two summers, Dadig has also worked as an intern at the Pennsylvania Department of Transportation (PennDOT). “I was the only woman in my internship program, sometimes the only one in the room,” she says.

But Dadig doesn’t let the lack of representation negatively affect her. “I was fortunate enough that growing up I was pushed to take those higher-level math and science courses. And now, even though there is definitely a gap for women in STEM, I don’t want to focus on that difference. I want to look ahead.”

Last February, Dadig was honored with fellow studentathletes as a Peter N. Stearns Provost Scholar Athlete, which means she has earned at least 38 credit hours at Mason and has achieved a cumulative grade point average of 3.75 or better. “Playing softball at Mason is a big plus, I came here for engineering, but I’m glad I’m able to play,” she says.

Dadig connects her success on the field to her success in the classroom and at her internship.

“Sports have definitely prepared me for a career in engineering.

Teamwork is key to success in softball and in engineering. You have to work together to win, and you have to work together to make sure structures are safe, or projects are completed.” g

Veteran Takes on New Normal Veterans are used to tackling new challenges, so when James Carsner, a veteran/ Mason Engineering student, was faced with the challenge of virtual learning, he was ready to take it on using his unique experiences.

A 20-year Navy veteran and civil and infrastructure engineering major, Carsner is no stranger to online courses. He earned his MBA online through the University of Phoenix while serving in the Navy, so the change this past spring wasn’t a huge leap for him.

“It was mainly a shift to balancing my time and no longer having to go onto campus. I had to figure out how to not let time slip away,” says Carsner.

Carsner says the approach faculty took online benefited him. “The professors kept the classes on the same schedule and made it live, which was great.

If we didn’t still have the lectures then it would’ve been more of a struggle.”

Carsner’s wife, who is still an active duty member of the Army, and their three children don’t live far from the Fairfax Campus, but the time that Carsner has gained by cutting his commute gave him more time to focus on the virtual learning.

“It takes planning and maturity.

You have to keep up with deadlines, double-check them, and be organized,” says Carsner. g
