Professor, Environmental Engineering & Science; Senior Fellow, Stanford Woods Institute for the Environment

Craig Criddle is a professor of environmental engineering & science, and a senior fellow at the Stanford Woods Institute for the Environment. His research focuses on environmental biotechnology, including large interdisciplinary field studies of microbial ecology in bioreactors and microbial transformations of persistent contaminants. Current projects include DNA-monitoring of microbial community structure at biological wastewater treatment plants, and development of membrane bioreactors for energy recovery and nutrient removal. To promote science literacy, Criddle collaborated with cartoonist Larry Gonick on The Cartoon Guide to Chemistry. Criddle earned BAs in civil and environmental engineering and Spanish at Utah State University, and a PhD in environmental engineering at Stanford.
