Wyatt Williams (Grad: Masters Student, Environmental Engineering | Business Administration) is interested in material use, disposal, and circularity with an emphasis on private supply chains. His research on circular economy topics focuses on indicator creation and scenario comparison. He uses life cycle assessment, material flow analysis, and techno-economic analysis to show secondary-material use’s economic, environmental, and social benefits. Outside of his research, Wyatt works as a solid waste consultant and spends his free time playing strategy games like Settlers of Catan and Hearthstone.

Samyuktha Swaminathan (Grad: Masters Student, Environmental Engineering) is currently working on the techno-economic implications of supply chain activities in transportation. Samyuktha has a background in Mechanical Engineering. During her undergraduate studies she worked as an intern at Ensys Technologies (an environmental services firm) in Chennai, India, where she was introduced to wastewater treatment, Life Cycle Assessment, Environmental Impact Assessments, and management plans. These experiences encouraged her to follow her passion in Environmental Engineering. Her research interests include green technology, circular economy, life cycle assessment and wastewater treatment. In her free time, she enjoys dancing, reading books, and trekking.  


Suemin headhshot

Suemin Lee (Undergrad, Civil Engineering) is from Pittsburgh, Pennsylvania. She is pursuing a B.S. in Civil Engineering with minors in Sustainable Cities and Computer Science. What attracted her to SEEL was learning how staples of our lifestyles— e.g., our diets, methods of transportation, and household products—affect our environment. Outside of the lab, she enjoys trying new foods, doing yoga, and working as a barista.


Preksha headshot

Preksha Jain (Undergrad, Civil Engineering) is a guacamole enthusiast, firstly attracted to join SEEEL because of the potential for sustainability initiatives within civil infrastructure systems. Society interacts with civil infrastructure daily, so having the opportunity to research and innovate through this lab has exciting potential to have a substantial impact!

Elshaday headshot

Elshaday Girma Berhanu (2022 – B.S. in Environmental Engineering) has lived in Ethiopia and Tunisia before coming to the U.S. for college. What attracted her to SEEEL was its overlap of equity, public policy, environmental sustainability, and climate change adaptation and mitigation solutions. Elshaday would like her research to have a positive impact on vulnerable and marginalized communities that face the effects of environmental and climate injustice in regions in and outside of the U.S.


Matthew headshot

Matthew Powell (2022 – B.S. in Chemical and Biomolecular Engineering) is from Miramar, Florida. During his pursuit of a minor in Public Policy, he became interested in how practices in policy and engineering tend to obfuscate the value-ladenness of design and operation decisions. He was attracted to SEEEL by their willingness to synthesize approaches from many disciplines and the emphasis on equity as a pillar of effective engineering. Outside of the lab, he enjoys reading an unreasonable backlog of used books, working on charcoal drawings, and lifting.


Paul headshot

Paul Ambrose (2022 – M.S. in Environmental Engineering) has the goal of applying the technical knowledge he learns from his classes to society good. He was initially attracted to SEEEL because of its mission of providing more equitable access to food and clean water for all socioeconomic backgrounds, given the current disparity in resource distribution. Paul would like to find ways to reduce food waste, while while improving food distribution outcomes that ensure hunger and poverty is reduced.


Sam headshot

Sam Beagle (Transitioned [2022]: Undergrad, Civil Engineering) was attracted to SEEEL because it not only works within engineering, but it also aims to have an impact on people in all fields of work and from all walks of life. SEEEL’s guiding principles make the work much more worthwhile, and he is very excited to be involved. Outside of SEEEL, he plays club soccer at Georgia Tech and watches a lot of soccer and basketball.
