Edward Chang

Associate Professor, University of California, San Francisco

Edward Chang MD is Co-Director of CNEP and Associate Professor of Neurological Surgery and Physiology at UCSF. Dr. Chang’s clinical expertise is surgical therapies for intractable epilepsy, trigeminal neuralgia, pain, and adult brain tumors. 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. Dr Chang’s research focuses on the neural mechanisms underlying our ability to speak and hear speech. His lab is translating this knowledge into a neuroprosthetic device that will allow paralyzed patients to speak and communicate.
