Joshua B. Bederson, MD, is the Leonard I. Malis, MD / Corinne and Joseph Graber Professor of Neurosurgery and System Chair for the Department of Neurosurgery at Mount Sinai Health System. An expert in skull-base and cerebrovascular surgery, his specialty interests include surgical treatments of complex intracranial and spinal pathology such as meningiomas, skull base tumors and aneurysms, schwannomas, craniopharyngiomas, pituitary tumors, giant intracranial aneurysms, acoustic neuromas, neurovascular compression syndromes such as trigeminal neuralgia, Chiari malformations, and trans-nasal minimally invasive brain surgery. His vascular practice includes treatment of aneurysms, arteriovenous malformations, carotid artery disease, moyamoya disease and extracranial-intracranial bypass procedures. Dr Bederson has performed more than 4,000 neurosurgical operations at Mount Sinai.
Dr. Bederson joined the faculty in 1992 as the Director of the The Clinical Program for Cerebrovascular Disorders and served as Vice-Chair from 2001 to 2008 and Director of the Residency Program from 2002 to 2009. He became Chair of the Department of Neurosurgery in 2008.
Dr. Bederson earned his medical degree and completed a residency in neurosurgery at the University of California in San Francisco. While a resident, he did advanced study programs in neuropathology at the University of Torino in Italy, as well as microvascular and skull-base neurosurgery at the University Hospitals of Zurich, Switzerland, and the University Medical Center in Ljubljana, Slovenia. He also completed a fellowship in cerebrovascular surgery at the Barrow Neurological Institute.
At The Mount Sinai Hospital, Dr. Bederson was the first neurosurgeon to receive an NIH-RO1 as principal investigator. He established the first basic science laboratory in the Department of Neurosurgery, developing models of stroke and subarachnoid hemorrhage. An advocate of collaboration with other accomplished physicians and scientists at Mount Sinai, Dr. Bederson developed one of the first interdisciplinary clinical programs with the Department of Neurology Stroke Program, and fostered collaborative efforts with the Department of Otolaryngology, the Tisch Cancer Institute, and the Translational Neuroscience Center. Now the Neurosurgery Simulation Core, Dr. Bederson launched the Brain Surgery Simulation Program in 2012.
Dr. Bederson previously served as the President of the New York Society for Neurosurgery and was Chair of the American Association of Neurological Surgeons/Congress of Neurosurgeons Cerebrovascular Section. Dr. Bederson is currently Chair of the American Heart Association's writing group on subarachnoid hemorrhage. In 2019, Dr. Bederson was honored at the AANS Annual Scientific Meeting as the Cerebrovascular Section's M. Gazi Yasargil Lecturer.
