Biography

Dr. Rajasekaran received his graduate degree from the University of Madras, India.  After completing his postdoctoral training at the University of Virginia, Charlottesville, he joined the faculty at UT Southwestern Medical Center as a member of the Rare Brain Disorders Program.  Dr. Rajasekaran's long term research objective is to understand how GABAergic neurotransmission orchestrates intercellular communication among neurons and how neural bioenergetics influences these processes, with the ultimate goal to develop therapies to prevent or abort rapidly evolving neuropathological conditions such as status epilepticus and traumatic brain injury as well as chronic conditions associated with metabolic encephalopathies.  A neuropharmacologist and electrophysiologist by training, Dr. Rajasekaran is passionate about epilepsy research and his research has been supported by grants from the Epilepsy Foundation of America and the American Epilepsy Society.
