UW Medicine


Andrew L. Ko is the Director of Functional and Restorative Neurosurgery at UW Medicine. He specializes in surgery for movement disorders, epilepsy, brain tumors and pain. Dr. Ko graduated from Dartmouth College with a bachelor's in philosophy before pursuing his medical degree at the University of Illinois, Chicago. He completed an internship in general surgery and a residency in neurological surgery at the University of Washington, followed by a fellowship in stereotactic and functional neurosurgery at Oregon Health and Sciences University.

His clinical interests focus on surgery for movement disorders, including Deep Brain Stimulation (DBS); surgery for epilepsy, including resection, laser ablation, and responsive neuromodulation; open and percutaneous treatments for chronic pain syndromes such as trigeminal neuralgia; and the mapping of brain function during surgery for tumors and epilepsy. His research interests include development of biomarkers of effective DBS, the development of a demand-driven DBS system for Essential Tremor, and the electrophysiological correlates of functional imaging of the brain.
