Edward Chang, MD, is the Joan and Sanford Weill Chair and Jeanne Robertson Distinguished Professor of Neurological Surgery at the University of California, San Francisco. Dr. Chang’s clinical expertise is surgical therapies for epilepsy, brain tumors, and cranial nerve disorders. He specializes in advanced neurophysiologic brain mapping methods, including awake speech and motor mapping, to safely perform neurosurgical procedures in eloquent areas of the brain. His research focuses on the discovery of cortical mechanisms of high-order neurological function in humans. Dr. Chang’s laboratory has demonstrated the detailed functional organization of the human speech cortex and has translated those discoveries towards the development of a speech neuroprosthetic device to restore communication for people living with paralysis. Dr. Chang is the 2015 Blavatnik National Laureate in Life Sciences and was elected to the National Academy of Medicine.
