Brent Harris, MD, PhD

Dr. Brent Harris is a physician-scientist and neuropathologist who joined the GUMC faculty as an Assoc Professor of Neurology and Pathology and Director of Neuropathology on the tenure line in 2010. He was among the first MD/PhD students to graduate in the newly formed MD/PhD Program at Georgetown University in 1995. Following Georgetown, he headed West to do his residency and fellowship in anatomic pathology/neuropathology at Stanford University and stayed to do a post-doctoral fellowship in neurobiology where we studied glial-neuronal interactions in disease and synaptogenesis. Dr. Harris took his first faculty position at Dartmouth Medical School where he helped establish and direct the ALS Center of DHMC. He was recruited to GUMC to fill a growing need in translational neurosciences at the Medical Center. Dr. Harris has clinical appointments at MGUH, Howard Univ Hospital, and the Washington VA Medical Center and serves as consultant for the Dept of Justice, DC Medical Examiner's Office, and the NIMH/NIH Human Brain Collection Core. He serves on the editorial boards for several scientific journals and is currently the Chair for the DOD ALS Therapeutic Idea Study Section. Dr. Harris is an active educator and serves as Module Director and Course Director for Medical and Graduate School courses. He is also the Director of the Georgetown Brain Bank. Dr. Harris' research interests include fluorescence guided resection of CNS tumors, neurodegeneration, and traumatic brain injury. His laboratory has funding from NIH, foundations, and philanthropic sources, and he is an active collaborator with investigators here at GUMC and other institutions.
