Dr. Geoffrey Colby is a neurosurgeon and expert specialist in the open microsurgical and minimally-invasive endovascular treatment of cerebrovascular disorders of the brain and spine. He is the Director of Cerebrovascular Neurosurgery and an Associate Professor of Neurosurgery and Radiology at UCLA. Dr. Colby uses the most modern and advanced techniques to treat cerebral aneurysms, arteriovenous malformations (AVMs), dural arteriovenous fistulas (dAVFs), subarachnoid hemorrhage (SAH), stroke, intracerebral hemorrhage (ICH), carotid stenosis, cavernomas, and Moyamoya. He is a world-class expert using flow diversion for treatment and cure of brain aneurysms. He also performs embolization of tumors of the brain and spine.

Dr. Colby’s research explores technical advances to improve patient outcomes and the development of novel devices to treat cerebrovascular disorders. He has co-authored more than 70 peer-reviewed scientific articles and book chapters, and he has served as the principal investigator for many clinical studies testing new endovascular devices to treat cerebral aneurysms and stroke. He has lectured around the world on 4 continents, and he is a reviewer for the main journals in the field of cerebrovascular disorders.

Dr. Colby joins UCLA from The Johns Hopkins University School of Medicine in Baltimore, where he was an Assistant Professor of Neurosurgery, Neurology and Radiology. During his tenure there, he performed thousands of neurosurgical procedures and was an avid researcher. His passion for teaching earned him the Department of Neurosurgery Chairman’s Award of Excellence, and the Neurosurgery house staff at Johns Hopkins presented him with the Richard J. Otenasek, Jr. Faculty Teaching Award. Dr. Colby received his M.D. and Ph.D. degrees from Columbia University in New York City. He completed his internship and neurosurgery residency at The Johns Hopkins Hospital, as well as a two-year fellowship in endovascular neurosurgery and interventional neuroradiology. He joined the Johns Hopkins faculty in 2013. Dr. Colby was recruited from Johns Hopkins to join the faculty of the UCLA Department of Neurosurgery.
