Julia Brody is senior scientist and executive director at Silent Spring Institute (www.silentspring.org) where she studies environmental chemicals and breast cancer, and the practice of community-engaged research. Her current research focuses on methods for reporting to people on their own exposures to hormone disruptors and other contaminants when the health effects are uncertain. She led a scientific review of evidence on animal mammary gland carcinogens and epidemiologic studies of breast cancer and environmental pollutants, diet, body size, and physical activity, which was published in the American Cancer Society journal Cancer and cited as a foundation for the Institute of Medicine breast cancer and the environment report. Silent Spring Institute is a nonprofit research organization founded by leaders of the Massachusetts Breast Cancer Coalition in 1994 to study environmental factors and prevention. Silent Spring researchers lead the most comprehensive assessment to date of exposure to hormone disruptors in US homes. Brody earned her PhD at the University of Texas at Austin and her AB at Harvard University.
