Translational Pharmacology and Neurotherapeutics of Epilepsy and Brain Disorders
Dr. Reddy has been in the pharmacology research field for over 23 years. His lab is mainly focused on drug development for epilepsy and brain disorders. Epilepsy and seizure disorders affect about 50 million people worldwide, including thousands of veterans and civilians in the US. He directs a productive multidisciplinary group utilizing pharmacological, electrophysiological, histological, mass spectrometric, and transgenic techniques. Current projects in the Reddy lab are centered on elucidating the molecular pathophysiology of, and developing mechanism-based novel drug therapies for, epileptogenesis, status epilepticus, post-traumatic epilepsy, post-stroke epilepsy, and chemical neurotoxicity. He has a long standing interest in neurosteroids as novel anticonvulsants. Dr. Reddy was instrumental in discovering many preclinical models, mechanism-based treatment strategies, and novel medicines for complex brain disorders. His lab has been conducting pioneering investigations on neurosteroid interactions at synaptic and extrasynaptic GABA-A receptors. His research has been continuously funded by the NIH for over 12 years. He is the principal investigator of an NIH Cooperative Agreement U01 project focusing on novel treatments for organophosphate and chemical nerve agent intoxication. He directs a DOD project on post-traumatic epilepsy after traumatic brain injury. He teaches both medical and graduate courses on human pharmacology and pharmacodynamics and mentors many undergraduates and doctoral & postdoctoral trainees. Dr. Reddy has published over 150 papers and book-chapters (h-index 40), which are available worldwide (http://orcid.org/0000-0003-2735-9550).
