Kevin Camphausen, M.D., joined the Radiation Oncology Branch (ROB) in July 2001, as a new principal investigator. Dr. Camphausen majored in biology at Purdue University, proceeded to medical school and internship at Georgetown University, and completed his residency at the Joint Center for Radiation Therapy in Boston in June of 2001. While in Boston he spent 2 years working in the laboratory of Dr. Judah Folkman, where he studied the interactions between radiotherapy and angiogenesis inhibitors. Dr. Camphausen has continued this work here and his lab is currently investigating the mechanisms underlying the synergy between radiotherapy and angiogenesis inhibitors.
