Dr. Leigh did his undergraduate training at Johns Hopkins University where he majored in Biomedical Engineering and Electrical & Computer Engineering. He then attended medical school at Case Western Reserve University and completed a medical internship and neurology residency at New York Presbyterian Hospital Weill Cornell Medical Center where he received the Distinguished Housestaff Award and was named Chief Resident in Neurology. He returned to Johns Hopkins for stroke fellowship and subsequently stayed on as neurology faculty with a secondary appointment in the department of radiology. In 2014, Dr. Leigh joined the stroke program at NINDS as an Assistant Clinical Investigator. Dr. Leigh is now an Associate Professor at Johns Hopkins Un.
Dr. Leigh's research interests are focused on using MRI to better understand disease states that occur at the interface between blood vessels and the brain. This encompasses acute cerebral ischemia caused by an occluded blood vessel as well as chronic cerebral ischemia that can be associated with dementia. The goal is to understand how MRI can serve as a biomarker for the natural history of cerebrovascular disease such that we may identify targets for therapy upon which to design clinical trials.
