I graduated form Yale University with a degree in Molecular Biophysics and Biochemistry. I then received my MD degree from the University of Pennsylvania. After completing my Internal Medicine Residency at the University of Michigan, I returned to the University of Pennsylvania for a fellowship in Pulmonary Medicine. I became interested in the field of Sleep Medicine there and was recruited to Brown in 1985 to start a clinical and research sleep program. I am currently the Director of the Sleep Disorders Center of Lifespan Hospitals. All three sites at Rhode Island Hospital, the Miriam Hospital and Newport Hospital are accrediated by the American Academy of Sleep Medicine. In 2008 I became the Vice Chairman for Operations. My research interests include obstructive sleep apnea, sleep in drug dependency states and sleep in hospital settings.
