Dr. Dhar is an Attending Physician in the Neurology/Neurosurgery Intensive Care Unit at Barnes-Jewish Hospital and carries out clinical research in neurological critical care. The focus of his research seeks to understand the brain’s response to the transfusion of red blood cells in patients at risk for cerebral ischemia after aneurysmal subarachnoid hemorrhage.
