Edward Chang is an American neurosurgeon and scientist. He is the Joan and Sandy Weill Chair of the Department of Neurological Surgery at the University of California, San Francisco and Jeanne Robertson Distinguished Professor.He has conducted pioneering research using intracranial electrophysiology to investigate how the brain processes language, revealing insights into the neural mechanisms underlying speech production and comprehension. Chang's work has implications for understanding communication disorders and has the potential to inform the development of neuroprosthetics and brain-computer interfaces. His interdisciplinary approach and innovative methods have expanded our understanding of the brain's intricate functions.
