Dr. Susan Korrick is an Instructor in Medicine at Harvard Medical School, a Lecturer in Occupational Health at Harvard School of Public Health, and an Associate Physician in the Department of Medicine, Channing Laboratory Division, at Brigham and Women's Hospital, Boston, Massachusetts. She is an internist, environmental and occupational medicine specialist, and epidemiologist. Dr. Korrick's primary professional activity is research and her current research is focused in three areas: (1) developmental and reproductive toxicities of organochlorine compounds; (2) chronic lead toxicities in middle-aged and elderly adults; and (3) the relationship between perimenopausal alterations in bone metabolism and changes in the kinetics of lead and its toxicity. Dr. Korrick is the Project Director/Principal Investigator of a longitudinal study of the impact of low-level intrauterine exposure to PCBs, pesticides, and lead on infant and child development. In related work she is investigating: (1) the role of hormones as modifying factors in the expression of PCB- and pesticide-associated developmental effects; (2) the association of environmental dioxin exposure with male pubertal development; and (3) the association of PCBs and pesticides with adverse reproductive health outcomes (e.g., infertility and spontaneous abortion). Dr. Korrick lectures in the Department of Environmental Health at Harvard School of Public Health on topics such as toxicology and reproductive epidemiology. Dr. Korrick received her B.A. in Biology from Harvard University, an M.D. from Yale University School of Medicine, and an M.P.H. from Harvard University School of Public Health.
