Dr. Larson specializes in functional neurosurgery, specifically deep brain stimulation, for a variety of neurological disorders. Previously, he was a professor in neurological surgery at the University of California San Francisco from 2001 to 2021.

Dr. Larson is a pioneer in the field of interventional MRI-guided stereotaxy for DBS, laser ablation and drug delivery, and has performed more than 1,000 iMRI procedures. His clinical research team has been the solo or lead group in 10 gene therapy clinical research trials since 2004, and has the world’s largest experience in intracranial delivery of novel therapeutics for neurodegenerative disorders. His NIH-funded research in tinnitus has led to the discovery of a new brain region involved in auditory perception.
