About

Dr. Nariai is currently an Assistant Professor of Pediatrics in the Division of Pediatric Neurology at UCLA. He specializes in pediatric epilepsy, specifically focusing on drug-resistant epilepsy and epilepsy surgery evaluation. He currently serves as the Medical Director of the Pediatric Epilepsy Surgery Program at UCLA. Dr. Nariai is board-certified in pediatric neurology, epilepsy, and clinical neurophysiology.

Dr. Nariai is actively involved in the UCLA Pediatric Epilepsy Surgery Program and the UCLA Infantile Spasms Program from both a clinical and research perspective. His research has been funded by the National Institute of Health (NIH), the UCLA Children's Discovery and Innovation Institute (CDI), the American Academy of Neurology, the American Epilepsy Society, the American Brain Foundation, and the Epilepsy Foundation.

In his ongoing research, Dr. Nariai is exploring EEG (electroencephalogram) biomarkers of epilepsy and conducting computational EEG analyses during epilepsy surgery. He aims to pinpoint the brain regions responsible for seizure generation and identify functional brain areas, to minimize complications associated with epilepsy surgery.

Dr. Nariai is an active member of the American Academy of Neurology (AAN) and the American Epilepsy Society (AES).
