Christopher Kellner, MD is an Assistant Professor in Neurosurgery specializing in the endovascular and minimally invasive treatment of different forms of stroke, aneurysms, arteriovenous malformations, dural arteriovenous fistulas, cavernous malformations, and other vascular problems of the brain and spine. He is Director of the Intracerebral Hemorrhage Program and Principal Investigator of the Cerebrovascular Translational Laboratory.

Dr. Kellner received his undergraduate degree from Harvard University and earned his medical degree from the College of Physicians and Surgeons at Columbia University. He also completed his neurosurgery residency training at New York Presbyterian - Columbia University. He then performed his endovascular fellowship at Mount Sinai with Drs. Alejandro Berenstein, J Mocco, Johanna Fifi, and Reade DeLeacy.

Dr. Kellner has authored over 60 peer-reviewed publications and 10 book chapters. His research focuses on improving outcomes in endoscopic minimally invasive intracerebral hemorrhage evacuation, decreasing brain inflammation after stroke, early diagnosis of stroke, and early diagnosis of cerebral aneurysms. He is the principal investigator of the VITAL study, a multicenter clinical trial evaluating the VIPS device, which is a non-invasive, portable, easy to use severe stroke detection device that can be used in the ambulance to correctly diagnose severe stroke to triage patients to the right hospital.

Dr. Kellner believes that the patient-doctor relationship is built on a foundation of understanding that comes from education, trust, and accessibility. He uses 3D models and virtual reality when possible to describe complex procedures to his patients. He also uses these technologies to rehearse a surgery prior to the real thing.
