Dr. William G. Nelson is the Marion I. Knott Professor of Oncology and Director of the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins.  He also serves as a Professor of Urology, Pharmacology, Medicine, Pathology, and Radiation Oncology at the Johns Hopkins University School of Medicine, and has a Joint Appointment in Environmental Health Sciences at the Johns Hopkins University Bloomberg School of Public Health. 

In addition to his administrative duties, he directs a research laboratory focused on discovering new strategies for prostate cancer treatment and prevention.  Along with fellow Johns Hopkins colleagues, he discovered the most common acquired genome defect in prostate cancer, a discovery which has led to new diagnostic tests for the disease and has fueled new drug discovery for disease treatment, now ongoing at the Hopkins Kimmel Cancer Center.

Outside of Johns Hopkins, Dr. Nelson has also become a recognized leader in translational cancer research.  As one of three co-chairs of the National Cancer Institute’s Translational Research Working Group, he worked to reengineer translational cancer science across the nation, helping to author a landmark report.  He has also been a member of the Scientific Advisory Boards of several companies focused on the development of new technologies and treatments for human cancer, a Co-Chair of the Scientific Advisory Committee for Stand Up 2 Cancer, and a member of the Scientific Advisory Boards/Committees for a number of foundations, including the Prostate Cancer Foundation, the Kimmel Scholars, the V Foundation, and many others.


Dr. Nelson completed his M.D. and Ph.D. training at the Johns Hopkins University School of Medicine, earning honors for both research and clinical excellence, and then pursued Internal Medicine residency training and Medical Oncology fellowship training at the Johns Hopkins Hospital, earning American Board of Internal Medicine certification in both disciplines.
