Jonathan Powell is a Professor of Oncology and Pharmacology at Johns Hopkins University School of Medicine. He received his AB from Dartmouth College and his M.D. Ph.D. from Emory University School of Medicine. His Post-graduate clinical training included the Osler Internal Medicine Residency Program at Johns Hopkins and Fellowship training in Hematology-Oncology at The Brigham and Women’s Hospital in Boston and NHLBI at the NIH. While at the NIH Dr. Powell was a post-doctoral fellow in the Laboratory of Dr. Ronald Schwartz. He joined the faculty of Johns Hopkins in 2001. Dr. Powell’s lab is interested in studying the cellular, biochemical and molecular mechanisms surrounding T cell activation, differentiation and tolerance. In elucidating fundamental insight into how the immune system is controlled, the lab has been investigating the role of mTOR and metabolism in immunology. This work established the principle that differential mTOR activation and subsequent metabolic pathway activation define T cell fate decisions. Overall, these studies have provided important insight into devising novel regimens for immunotherapy for cancer, bone marrow transplantation, autoimmune & inflammatory diseases. Dr. Powell is currently an Associate Director of the Bloomberg~Kimmel Institute for Cancer Immunotherapy and is the head of the program of Cancer and Immuno- metabolism.
