About

Joyce Matsumoto received Bachelor of Science degrees in Biology and Chemistry with a Biochemistry emphasis from Pacific Union College, then received her MD from Loma Linda University. She has been in the University of California system ever since, completing Neurology residency at UCLA, Epilepsy fellowship at UCSF, then returning to UCLA to join the Pediatric Neurology faculty. 

She is the medical director of the UCLA Ketogenic diet therapies program, and is currently the director of the Pediatric EEG lab at Ronald Reagan and UCLA Santa Monica hospitals. Her research interests include exploring potential medical benefits of ketosis for conditions outside of epilepsy, as well as continuous EEG monitoring in critically ill patients.
