Kathryn Terry, Sc.D.
Co-Scientific Director (BWH)

Kathryn Terry, ScD

Dr. Kathryn Terry, an Associate Professor at Harvard Medical School in Obstetrics, Gynecology, and Reproductive Biology and Associate Epidemiologist at Brigham and Women’s Hospital, became interested in epidemiology while working in the clinical trials department at Memorial Sloan-Kettering after college. During her doctoral training at the Harvard T.H. Chan School of Public Health, she straddled the fields of reproductive and cancer epidemiology in her work on genetic variation in hormone receptors and ovarian cancer risk. After graduating in 2005, she pursued a postdoctoral fellowship at the Channing Laboratory at Brigham and Women’s Hospital where she worked with Dr. Stacey Missmer on projects evaluating dietary factors in relation to risk of uterine leiomyoma in addition to her work with other faculty on risk of hormonal factors in relation to reproductive cancers. Dr. Terry has received several foundation grants to evaluate risk factors, genetic variants, and tissue markers in relation to ovarian cancer risk and prognosis. Most recently, she received a four year grant from the National Institutes of Health to develop a model for personalized screening for ovarian cancer that leverages personal characteristics and genetic variants to optimize the most promising biomarkers to date. Dr. Terry is active in international collaborative efforts and serves as the chair of the Epidemiology Working Group for the Ovarian Cancer Association Consortium. In addition, Dr. Terry in a co-investigator on the COMPARE-UF national fibroids registry and teaches a course on reproductive epidemiology and at the Harvard T.H. Chan School of Public Health.
