Janice S. Lee, PhD

Adjunct Associate Professor
Department of Environmental Sciences & Engineering


Janice S. Lee, PhD., is a supervisory biologist at the U.S. EPA’s Center for Public Health and Environmental Assessment (CPHEA). Dr. Lee was a toxicologist at the Division of Public Health in Madison, Wisconsin, from 2002-2005. She was the technical consultant for environmental exposure assessment and health risk assessment, as well as being the lead toxicologist for developing the public health response to chemical hazards and threats. Dr. Lee was a postdoctoral fellow in the Toxicogenomics Core in the National Health and Environmental Effects Research Laboratory (NHEERL) at EPA where she received training in aging/life stages and transcriptomics. Dr. Lee received her PhD in environmental health sciences from the University of Michigan in 2002 where her doctoral work focused on arsenic chemistry and health effects. She is interested in susceptibility and the application of novel methods to improve human health risk assessment. She is currently leading the IRIS Toxicological Review of tert-butanol, and is co-chemical manager of the Inorganic Arsenic Toxicological Review.
