Dr. Leonard Levin is a tenured professor in the Departments of Ophthalmology and Neurology and Neurosurgery at McGill University, and chair of the Department of Ophthalmology. He is a physician-scientist at the Neuro, where he does research related to optic nerve diseases and related disorders.

Dr. Levin received a bachelor’s degree magna cum laude in applied mathematics at Harvard, where he did an honors thesis designing a language for computer-assisted music composition. He did his MD in the Harvard/MIT joint program in Health Science and Technology, with a PhD in neurobiology, focusing on research relevant to multiple sclerosis. He then pursued an ophthalmology residency and neuro-ophthalmology fellowship at the Massachusetts Eye and Ear Infirmary.

His research program focuses on mechanisms of retinal ganglion cell death at the molecular, tissue culture, and whole animal level. This includes the role axonal damage plays in inducing loss of retinal ganglion cells and how axons themselves undergo injury, an area common to ophthalmology and neurology. He is particularly interested in using advanced imaging techniques to study signaling of cell death in the retina and the development of new drugs for optic nerve and retinal disease. This and related research has resulted in more than 160 peer-reviewed papers, reviews, and book chapters, 4 issued patents, and his editing of five textbooks in the visual sciences or ophthalmology, including Ocular Disease: Mechanisms and Management, and the recent 11th edition of Adler’s Physiology of the Eye. He is past chair of the Diseases and Pathophysiology of the Visual System study section at the United States National Institutes of Health and has been an ad hoc reviewer for the Canadian Institutes of Health Research, and funding bodies in Britain, Hong Kong, Israel, Australia, and elsewhere.

Dr. Levin is also interested in the challenges associated with successfully translating basic science research into clinically effective therapies, and has been involved with the design and assessment of clinical trials to study neuroprotective therapies in various optic neuropathies.
