Bruce Jeffrey Trock, M.P.H., Ph.D.
Director, Division of Epidemiology, Brady Urological Institute at Johns Hopkins
Professor of Urology
Research Interests: Breast cancer; Prostate cancer; Biomarkers of age-related change in the prostate; Biological mechanisms of aging
Dr. Bruce Jeffery Trock is a professor of urology, epidemiology, oncology and environmental health sciences at the Johns Hopkins School of Medicine. He serves as the Director of the Division of Epidemiology in the Brady Urological Institute at Johns Hopkins. His research focuses on breast and prostate cancers.
Dr. Trock received undergraduate degrees in mathematics and physiology at the University of Michigan and Michigan State University, respectively. He returned to the University of Michigan for a master’s in public health with an emphasis in epidemiology, and then completed a Ph.D. in epidemiology at the Johns Hopkins University School of Public Health.
In addition to his faculty appointments at Johns Hopkins, Dr. Trock acts as the Director of the Prostate Cancer Biorepository Network, a collaboration between the Johns Hopkins University School of Medicine, the New York University School of Medicine and the United States Department of Defense that works to acquire high quality, well-annotated biological specimens of advanced stage prostate cancer in order to develop more targeted research investigations that can aid in understanding, treating and ultimately curing the disease.
Dr. Trock has authored or co-authored more than 130 published articles and has been principal or co-principal investigator on numerous research grants. He is a member of the Society for Epidemiologic Research, the American Society of Preventive Oncology and the American Association for Cancer Research.

Research & Publications
Dr. Trock’s research focuses on biomarkers for the early detection and prognosis of prostate and breast cancer, comparative effectiveness of prostate cancer treatments and etiologic mechanisms (e.g., oxidative stress, senescence pathways, inflammation and diet). He is also interested in statistical issues involving biomarkers and statistical models to explore the relationship between aging and prostate cancer, as well as common pathways linking breast and prostate cancer etiology.
