Jeffery D. Kocsis, PhD, is professor of neurology and neurobiology at the Yale University School of Medicine and senior research career scientist in the Department of Veterans Affairs. He is the associate director of the Center for Neuroscience Regeneration and Research at the West Haven VA Medical Center of Excellence for the Restoration of Function in Spinal Cord Injury and Multiple Sclerosis. Dr. Kocsis received his PhD in anatomy (neuroscience) from Wayne State University School of Medicine and subsequently engaged in post-doctoral studies in the Department of Neurology at the Harvard Medical School and the Research Laboratory of Electronics at the Massachusetts Institute of Technology. He joined the faculty in the Department of Neurology at Stanford Medical School and the Palo Alto VA Medical Center before moving to Yale University. Dr. Kocsis is internationally recognized for his research on axonal pathophysiology and cellular transplantation approaches toward functional recovery in diseases of the brain and spinal cord. He has published more than 230 scientific publications. He is currently associate editor for several scientific journals. Dr. Kocsis has trained over 80 neuroscientists and academic neurologists who work at institutions around the world. He was awarded the 2007 Distinguished Graduate Alumnus from Wayne State University Medical School and the Di Vinci Lifetime achievement Award in 2009. Dr. Kocsis’s work has established the potential of cellular transplantation approaches for the repair of the injured nervous system. A research emphasis has been on remyelination by transplantation of myelin-forming cells into experimental models of demyelination and spinal cord injury. His laboratory first demonstrated that the conduction in demyelinated spinal cord axons is restored after remyelination by transplanted cells. They demonstrated that the normal pattern of ion channel distribution is reestablished in demyelinated spinal cord axons after cellular transplantation and remyelination. With his colleagues they have pioneered the study of intravenous infusion of bone marrow derived mesenchymal stem cells as a therapeutic strategy in spinal cord injury and stroke, and clinical studies for stroke and spinal cord injury are ongoing.
