Anna Pollack’s research focuses on the relationship between environmental chemical exposures and fertility, pregnancy, and gynecologic health. Critical to understanding these endpoints, she investigates biological mechanisms underlying these processes, such as biomarkers of oxidative stress, inflammation, and endocrine disruption. Dr. Pollack’s research is based in the theory of critical windows of exposure, which emphasizes that the timing of chemical exposures can result in permanent changes. Dr. Pollack’s research also addresses disparities in exposure, which stem from environmental and occupational sources. She seeks to apply methods to examine complex mixtures to better understand their impact on women’s reproductive health.

Prior to joining George Mason University in 2013, Dr. Pollack was trained in reproductive and environmental epidemiology, and epidemiologic methods. She received her PhD in epidemiology from Johns Hopkins University, MPH in environmental and occupational health from George Washington University, and BA in biology from Smith College. She completed a post-doctoral fellowship at the Eunice Kennedy Shriver National Institute of Child Health and Human Development.
