  • Kevin Sheth

    Professor of Neurology and Neurosurgery; Associate Chair for Clinical Research, Department of Neurology; Division Chief, Neurocritical Care and Emergency Neurology; Director, Neuroscience ICU

    After completing training in neurology and a fellowship in vascular neurology and neuro-critical care at Harvard, he was appointed the first neurology trained neuro-intensivist at the University of Maryland and R Adams Cowley Shock Trauma Center. At Yale, he is the founding Chief of the Division of Neurocritical Care & Emergency Neurology and Associate Chair for Clinical Research for the Department of Neurology. His interests are in the advancement of therapies for devastating acute neurological syndromes, especially those complicated by brain ischemia, swelling and hemorrhage. He is a nationally recognized clinical and translational scientist and has directed several multicenter studies. In pioneering the development of new strategies to treat brain swelling, his work has changed the fundamental approach to brain injury in the ICU and spurned the creation of new technologies in drug delivery and neuroimaging. His research group uses clinical trials as a platform for discovery, which includes novel imaging and serum based biomarkers for the neuro-ICU. In recent years, this platform has expanded to trials of prevention and recovery in brain injury. His team at Yale has served as a national model for academic critical care neurology units.

    He is currently the principal investigator for two NIH U24 Neuroscience Networks, NeuroNEXT and StrokeNet and three additional RO1/UO1 awards from the NIH. Dr. Sheth has served as PI or co-PI for 8 multicenter clinical trials in stroke, as well as chair for clinical endpoint and data safety monitoring committees for several pivotal studies.
