Lee Institute for Health Policy Studies. She is a recognized expert on environmental pollution exposures and impacts on health, with a focus on pregnancy, infancy and childhood, and her innovations in translating and communicating scientific findings for clinical and policy audiences. She has authored numerous scientific publications and book chapters, and has been quoted widely in the press, including USA Today, the San Francisco Chronicle and The New York Times. Before joining UCSF, Dr. Woodruff was a senior scientist and policy advisor for the U.S. EPA’s Office of Policy.

Nicholas Chartres, PhD formerly led the Science & Policy team at PRHE. He has extensive experience in the use of systematic review methods. As the lead author of the first in-depth study on how industry sponsorship influences nutrition research, he is an expert in identifying and analyzing industry influence and developing methods to reduce industry bias in the research process. In addition to his work as a consultant for PRHE, Dr. Chartres is part of the World Health Organization/International Labor Organization (WHO/ILO) Joint Estimates Working Group examining global work-related burden of disease and injury.

Swati Rayasam, MSc is a Science Associate for the Science & Policy team at PRHE. She has been one of the leads on the team for PRHE’s work to ensure EPA’s implementation of the Toxic Substances Control Act protects the health of communities disproportionately impacted by toxic chemical pollution such as BIPOC, low-income populations, incarcerated populations, and people with disabilities. She earned her MSc in Global Health and the Environment from the University of California, Berkeley’s School of Public Health and her BS in Biology from the University of North Carolina, Chapel Hill.
