Dr. Gary Steinberg is the Founder and Co-Director of the Stanford Stroke Center, former Chair of Neurosurgery, and Director of the Stanford Moyamoya Center. His 33 years of experience in basic and translational neuroscience research has focused on hemorrhagic and ischemic stroke, as does his neurosurgical clinical practice. As a cerebrovascular neurosurgeon, he specializes in treating brain aneurysms, moyamoya disease, brain and spinal AVMs and other vascular malformations, carotid artery disease and skull base tumors. His lab investigates pathomechanisms of cerebral ischemia, develops neuroprotective agents, and employs novel approaches such as stem cell transplantation and optogenetic stimulation to enhance post-stroke functional recovery. He has pioneered microsurgical techniques to repair intracranial vascular malformations and certain aneurysms that were previously considered untreatable. He has also refined revascularization techniques for patients with cerebrovascular arterial occlusions, including moyamoya disease. He has successfully translated his preclinical work into several stem cell clinical trials for stroke, spinal cord injury and traumatic brain injury, as well as leading numerous other clinical cerebrovascular trials.
