Kevin Pelphrey, PhD
About
Biography
Kevin Pelphrey is an internationally renowned neuroscientist and the parent of a young woman with autism. He utilizes brain science to develop biologically-based tools for detection, stratification and individually tailored treatments. He leads the NIH Autism Center for Excellence—Multimodal Developmental Neurogenetics of Autism network that spans seven national sites. He directs an NIH postdoctoral training program to prepare scientist-clinicians for independent careers translating multidisciplinary science into novel treatments for neurodevelopmental disorders. At George Washington University, Dr. Pelphrey is the Carbonell Family Professor and director of the Autism and Neurodevelopmental Disorders Institute. The institute serves as a focal point for translational research and comprehensive clinical services for autism, while also serving as a beacon for policymakers seeking information on issues surrounding policy, research and treatment of autism.
