 Overview 
 overview
Sonia Hernandez-Diaz, M.D., Dr.P.H. a physician and epidemiologist, is the Director of the Pharmacoepidemiology Program and Associate Professor of Epidemiology at the Harvard School of Public Health. Her research focuses on the evaluation of the comparative effectiveness and safety of pharmaceuticals and medical devices, with a special emphasis in pregnant populations. Dr. Hernández-Díaz has considerable experience in the design, conduct, analysis, and interpretation of data relating to the safety of drugs during pregnancy. She has collaborated in studies using Medicaid, GPRD, THIN and other large healthcare research databases, in addition to ad hoc case control studies and pregnancy registries. Another area of interest concerns the application of causal structural approaches to define confounding and selection biases in ways that facilitate the identification, communication, and resolution of common analytical problems in non-randomized studies. Dr. Hernández-Díaz has served as a member of the board of directors of the International Society for Pharmacoepidemiology and as a Special Government Employee and Voting member for the Drug Safety and Risk Management Advisory Committee of the US Food and Drug Administration.
