Principal Investigator
Professor of Neurology, Pathology and Epidemiology
Neurologist-in-chief, The Johns Hopkins Hospital

Dr Justin McArthur received his medical degree from Guys Hospital Medical School at the University of London. He then completed an internship and residency in Internal Medicine at The Johns Hopkins Hospital. Dr McArthur stayed at Johns Hopkins to complete a second residency in Neurology and to achieve a master’s degree in public health.
Now a Professor of Neurology, Pathology, Medicine and Epidemiology, Dr McArthur has become nationally and internationally recognized for his work in the epidemiology and treatment of HIV infection, multiple sclerosis, and other neurological infections and immune-mediated neurological disorders. He has been instrumental in the design and conduct of numerous clinical trials for these disorders. With Jack Griffin, he also developed a clinically-validated technique to use cutaneous nerves to study sensory neuropathies, including those associated with chemotherapy, HIV infection, and diabetes mellitus. He was recipient of the Department of Medicine Osler Housestaff Award in recognition of outstanding contributions to Housestaff teaching for four years, and the JHU Professor’s Award for Distinction in Teaching in the Clinical Sciences.
Dr McArthur is currently the Director of the Department of Neurology at Johns Hopkins and is also the Director of the Johns Hopkins/National Institute of Mental Health Research Center for Novel Therapeutics of HIV-associated Cognitive Disorders. The Center is comprised of an experienced interdisciplinary research team who have pooled their talents to study the nature of HIV-associated cognitive disorders. The aim is to translate discoveries of the pathophysiological mechanisms into novel therapeutics.
