Research & Publications
Dr. Punjabi’s current research focuses on the epidemiology of sleep apnea with a particular emphasis on associated sequelae, including insulin resistance, type 2 diabetes mellitus and cardiovascular disease. He has been one of the principal investigators for the multi-center Sleep Heart Health Study, an epidemiological study on the longitudinal effects of sleep apnea on hypertension, cardiovascular disease and mortality. His clinical research laboratory is examining the independent effects of intermittent hypoxia on various pathways to help elucidate the links between sleep apnea, insulin resistance and metabolic dysfunction.
