Irva Hertz-Picciotto, Ph.D., is an epidemiology professor at UC Davis MIND Institute, and chief of the environmental and Occupational Health. She is an internationally renowned environmental epidemiologist with over 250 scientific publications addressing environmental exposures, including metals, pesticides, air pollutants and endocrine disruptors, their interactions with nutrition, and their influences on pregnancy, the newborn, and child development. In 2002, she turned her attention to autism, launching the CHARGE Study, the first large, comprehensive population-based study of how environmental exposures influence autism, which has led to key discoveries of both risk and protective factors. A few years later she launched MARBLES (Markers of Autism Risk in Babies – Learning Early Signs), to search for early environmental and biologic predictors of autism, the first such study to begin in pregnancy. She also collaborates on the multi-site EARLI study, and was Director of the Northern California Center for the National Children’s Study. Dr. Hertz-Picciotto sits on editorial boards for four major scientific journals in epidemiology, environmental health, and autism, has held appointments on state, national and international advisory panels to organizations such as the Food Safety in Europe Working Group, U.S. Environmental Protection Agency, National Toxicology Program, California Air Resources Board, and NIH Interagency Coordinating Committee on Autism Research, and served as President of two of the largest professional epidemiology societies. She chaired the Expert Panel on CDC’s Vaccine Safety Database for Studies of Autism and Thimerosal and two National Academy of Sciences/Institute of Medicine (IOM) Panels, including two on Agent Orange and Vietnam Veterans and in 2011, the IOM Committee on Breast Cancer and the Environment. Dr. Hertz-Picciotto has taught epidemiologic methods on four continents and mentored over 60 doctoral and postdoctoral scholars.
