Keegan Cooke

Prior to coming to Stanford, Keegan acted as Principal Research Scientist for Trophos Energy Inc. – a start-up which had focused on the commercialization of undersea microbial fuel cell technology – until the company was successfully acquired in 2010. He currently serves as Executive Director for Keego Technologies, LLC – a small product design company, which combines primary science education with crowd-sourced technology development ( ) – and is involved in other technology projects, such as ultra-low-cost PCR machines, SODIS indicators, and assistive technologies.

Yoshika Crider

Yoshika graduated in 2013 with a BS and MS in Environmental Engineering, with a minor Human Biology. She continues to work with other Poop Group members to design a low-cost chlorine diffuser as part of a community-level water disinfection project in Dhaka, Bangladesh. She began her PhD work at the University of California-Berkeley in autumn of 2015.

Angela Harris

Angela completed her PhD in Environmental Engineering and Science (EES) in 2015, focused on the measurement and mechanisms of biological contamination of drinking water in resource-constrained environments. Angela received her BS in Chemical and Biomolecular Engineering from the Georgia Institute of Technology, and her MS in Environmental Engineering & Science at Stanford in 2010.

Jeanette Laramee

Jeannette completed her PhD in Civil and Environmental Engineering in 2017. Her dissertation research investigates the life cycle resource use, carbon impacts and financial costs of decentralized sewered and non-sewered sanitation systems with integrated energy resource recovery. Jeannette is also a registered Professional Engineer who has more than a decade of work and research experience designing, building and analyzing infrastructure in the United States, Zambia and Tanzania.

Mia Mattioli

Mia Mattioli completed her PhD student in Environmental Engineering and Science in 2014, focusing on the risk of diarrheal diseases to children in developing countries from different exposure routes in their environment. She now works with the WASH Laboratory team at the Centers for Disease Control in Atlanta.

Maika Nicholson

Maika graduated in 2013 with an MS in the Environmental Fluid Mechanics and Hydrology program and an Engineer’s Degree from the Civil and Environmental Engineering department. She worked on the impacts of water-resale in peri-urban Maputo, Mozamibque, and her own research focused on modeling the water source choices made by Maputo households.

Amy Pickering

Amy J. Pickering earned a Ph.D in Environment and Resources from Stanford's E-IPER program in 2011. Amy uses social science, epidemiology, and microbiology to understand diarrheal disease transmission pathways among households in low-income countries and develop strategies to interrupt them. She has led numerous field studies in South Asia and Africa. Amy began a tenure-track faculty position at Tufts University in 2017.

Kory Russel

Kory is a PhD candidate in the Environmental Engineering & Science program of the Civil and Environmental Engineering Department.  His dissertation research includes both (1) the human costs of water fetching and (2) developing innovative approaches for sanitation services in low-income urban areas. Kory has conducted extensive fieldwork in Mozambique and Haiti. He is currently an Acting Assistant Professor in the University of Oregon's Department of Landscape Architecture.

Shreyan Sen

Shreyan is a first year graduate student in the Environmental Engineering and Science program within the Civil and Environmental Engineering Department at Stanford, and a Returned Peace Corps Volunteer (Republic of Guinea). He is fluent in Bengali and currently works on water & sanitation projects in Bangladesh.

Lauren Steinbaum

Lauren completed her PhD in the Environmental Engineering & Science program in 2017.  Her research interests include soil-transmitted helminths, rural sanitation technologies, and decentralized wastewater treatment. As part of her dissertation work, Lauren carried out extensive fieldwork in Kenya investigating transmission pathways of soil-transmitted helminths, particularly Ascaris, Trichuris, and hookworm. 

Sebastien Tilmans

Sebastien completed his PhD in 2014. His dissertation research focused on energy recovery from wastewater, and how this recovery can improve the long-term operation and maintenance of sanitation systems. He carried out fieldwork in Panama and Haiti, as well as  work the Oceanside Water Pollution Control Plant. Since graduating, Sebastien has served as the inaugural Director of Operations for Stanford's Codiga Resource Recovery Center.

Eric Wilburn

Eric will complete a dual MS program in Environmental Engineering & Science and International Policy Studies. Eric served as a Peace Corps Volunteer in Mozambique, where he became interested in water and sanitation issues in low- income countries. He has also worked with the Natural Capital Project on water resources management and human health in Brazil.

Valentina Zuin

Valentina completed her PhD with the Emmet Interdisciplinary Program in Environment and Resources (E-IPER) in 2014. Her dissertation focused on water service delivery in peri-urban areas of Mozambique. Subsequently she became a faculty member at Ashoka University in New Delhi, and is now a post-doctoral fellow at Yale-NUS in Singapore.
