Elizabeth A. Platz, ScD, MPH is a Professor and the Martin D. Abeloff, MD Scholar in Cancer Prevention in the Department of Epidemiology at the Johns Hopkins Bloomberg School of Public Health, where she directs the NCI-funded (T32) training program in Cancer Epidemiology, Prevention, and Control. She also co-leads the Cancer Prevention and Control Program at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins and holds joint appointments in the Department of Oncology, and the Department of Urology and the James Buchanan Brady Urological Institute at the Johns Hopkins University School of Medicine. She received her doctorate in epidemiology from and was a post-doctoral fellow at the Harvard School of Public Health. A major focus of her work is the use of molecular and genetic epidemiology approaches to understand the mechanisms underlying prostate incidence and progression. She conducts her work with an eye toward translation of findings into prevention and treatment strategies. Known for her leadership of multidisciplinary prostate cancer research teams, she is at the forefront of epidemiologic research on the role of inflammation, a target for prevention, in the development of prostate cancer, and on telomere length as a prognostic marker for poor outcome after treatment for prostate cancer. She is the editor-in-chief of the American Association for Cancer Research’s Cancer Epidemiology, Biomarkers, and Prevention. She is an elected (2019) Fellow of the American Association for the Advancement of Science (AAAS) “For distinguished contributions to our understanding of the roles of genetics, epigenetics, and environmental factors in cancer epidemiology.” In addition to her academic efforts, she is appointed by the governor to the Maryland State Council on Cancer Control, and is a Steering Committee member and former chair of the Maryland Cancer Collaborative.
