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 and serves as Associate Director of the Neurosurgery Residency Program.

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

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 whenever possible to describe complex procedures to his patients. He also uses these technologies to rehearse a surgery prior to the real thing.

Precision Recovery - Fight Against Coronavirus Pandemic
In the fight against the coronavirus pandemic, Mount Sinai Health System announced a new remote monitoring platform to help provide care and monitor COVID-19 patients who are recuperating at home, Precision Recovery Platform. Dr. Kellner co-developer of the platform, said the technology will play a "massive role" in the crisis. The database was originally used for stroke victims but has been adapted for COVID-19 patients whose symptoms are not severe enough to be hospitalized.

Read about how Dr. Kellner adapted Precision Recovery to help more than 800 COVID-19 patients in the 2020 Neurology & Neurosurgery Specialty Report.
