Dr. Bruce Jeffrey Trock is the Frank Hinman Jr. endowed Professor of Urology, and is Professor of Epidemiology and Oncology 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 prostate cancer.  Prior to joining Johns Hopkins, Dr. Trock was a tenured associate professor at Georgetown University’s Lombardi Cancer Center, where he was also Director of the Cancer Biomarker Resource, with prior positions at the Fox Chase Cancer Center, and the University of Pennsylvania.

In addition to his faculty appointments at Johns Hopkins, Dr. Trock is the Director of the Biostatistics Core for the Johns Hopkins Specialized Program of Research Excellence (SPORE) in Prostate Cancer.  He also was the founding Director, and is now Co-Director of the Prostate Cancer Biorepository Network, a collaboration between the Johns Hopkins University School of Medicine, the New York University School of Medicine, University of Washington, the Institute of Cancer Research (London), Washington University,  and the United States Department of Defense that provides high quality, well-annotated prostate cancer tissues and biospecimens to prostate cancer researchers worldwide.

Dr. Trock has authored or co-authored more than 270 published articles and has been principal or co-principal investigator on numerous research grants. more

Research & Publications

Research Summary

Dr. Trock’s research goal is the use of biomarkers to better understand prostate cancer etiology, and to advance a precision medicine approach to prostate cancer prognosis and predicting response to therapies.  His academic contributions bridge epidemiology, biostatistics, basic sciences, and clinical trials, with a clear translational focus.   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.
