PRINCIPAL INVESTIGATOR
Douglas H. Smith, MD

The Robert A. Groff Endowed Professor and Vice Chairman for Research and Education in Neurosurgery
215-573-3156
Douglas H. Smith, MD, is the Robert A. Groff Endowed Professor Neurosurgery and Director of the Center for Brain Injury and Repair at the University of Pennsylvania. In addition, Prof. Smith is the Scientific Director of the Big 10/ Ivy league Colaboration on Concussion and he also serves as a member on the Scientific Advisory Boards of the US National Football League (NFL), the National Collegiate Athletic Association (NCAA)-DoD consortium on concussion and the International Concussion Society. In addition, the U.S. State Department asked him to lead an investigation into neurological deficits induced in members of the embassy in Cuba, which led to a newly discovered disorder, “Havana Syndrome.” Prof. Smith’s group has established that damage to brain networks and specifically, diffuse axonal injury (DAI), represents key pathological processes underlying concussion symptoms and that the extent of acute axonal pathology is predictive of cognitive outcome. In addition, his group has discovered mechanisms of concussion and more severe TBI that lead to progressive neurodegeneration, including chronic traumatic encephalopathy. These collective efforts are represented in over 250 published scientific reports earning an h-index of over 85. His awards include the Dorothy Russell medal, the highest honor conveyed by the British Neuropathological Society and the William Osler Patient Oriented Research Award from the University of Pennsylvania.
