Dr. Theodore DeWeese is a professor of radiation oncology and molecular radiation sciences, oncology and urology at the Johns Hopkins School of Medicine. His areas of clinical expertise include prostate cancer, radiation oncology and urological oncology.
He and his colleagues devised the first adenoviral gene therapy trial for prostate cancer, using a common cold virus to target cancer cells while leaving normal cells unharmed.
Dr. DeWeese serves as the director of the Department of Radiation Oncology and Molecular Radiation Sciences and Vice President of Interdisciplinary Patient Care for Johns Hopkins Medicine.
Dr. DeWeese received his B.A. from Metropolitan State College of Denver. He earned his M.D. from the University of Colorado Health Sciences Center. He completed his residency at The Johns Hopkins Hospital and performed a fellowship in urologic oncology at the Johns Hopkins Oncology Center and the James Buchanan Brady Urological Institute.
Previously at Johns Hopkins, Dr. DeWeese was an associate professor in oncology and urology and, later, the director of the radiation biology research program.
Dr. DeWeese's research interests include prostate cancer, DNA damage and radiation sensitization.
Dr. DeWeese has served on committees for the American Association for Cancer Research and the American Society for Therapeutic Radiology and Oncology. He has received numerous awards and honors, including two teaching awards from the Johns Hopkins Kimmel Cancer Center and an appointment as chief resident of radiation oncology at The Johns Hopkins Hospital in 1993-1994.

Research & Publications
Dr. DeWeese's research focus is on identifying DNA repair enzymes that, if inactivated, would result in substantial radiation sensitization. His team has synthesized a chimeric molecule in which a siRNA-targeting DNA repair protein is combined with an aptamer targeting the prostate-unique protein, prostate specific membrane antigen (PSMA). This results in a chimeric siRNA-apatmer that is a potent, targeted radiosensitizer with potential for translation into prostate cancer therapy.
