Alan Schwartz, MD

Alan Schwartz is a Professor of Medicine at Johns Hopkins University, and is director of the Johns Hopkins Sleep Disorders Center and the Center for Interdisciplinary Sleep Research and Education. Dr. Schwartz graduated from the Johns Hopkins School of Medicine, completed his residency in Internal Medicine at Mount Sinai Medical Center, and fellowship in Pulmonary, Critical Care and Sleep Medicine at the Johns Hopkins School of Medicine. He has investigated mechanisms of sleep disordered breathing with a special emphasis on novel approaches to the diagnosis and management of this disorder. He is an author of over 150 articles and three patents, and is an established investigator with a long track record in NIH and industry sponsored research studies.
