Douglas H. Smith 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, Dr. Smith is the Scientific Director of the Big 10/ Ivy league Collaboration 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.  Furthermore, Dr. Smith serves as a trustee of Mind Your Brain Foundation.  Notably, the U.S. State Department asked Dr. Smith to lead an investigation into neurological deficits induced in members of the embassy in Cuba, which led to a newly discovered disorder, “Havana Syndrome.” Dr. 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 that have been extensively cited. His awards include the Dorothy Russell medal, the highest honor conveyed by the British Neuropathological Society, the William Osler Patient Oriented Research Award from the University of Pennsylvania and the Anthony B. Marmarou Memorial Neurotrauma Lecture Award from the American Association of Neurological Surgeons and Congress of Neurological Surgeons.
