Lorelay has a PhD in Civil and Environmental Engineering from Stanford University, where she built expertise in turning research into practical, scalable solutions. Her doctoral work developed methods for wastewater-based epidemiology at large US treatment plants, studied virus decay in semi-centralized systems in Senegal, and evaluated failing onsite sanitation infrastructure in rural Alabama. Lorelay also co-developed the course “The role of water and energy for circular economies”. Prior to the PhD, she interned at the World Health Organization in Geneva, where she became passionate about the connections between water, health, and society. She earned her M.S. in Civil and Environmental Engineering at Stanford and her B.S. in Civil, Construction, and Environmental Engineering at San Diego State University. At Trussell, Lorelay leads sampling efforts for pilot-scale potable reuse projects and uses those insights to inform the design of larger water treatment processes.
