Sairam Parthasarathy is Professor of Medicine, Division Chief of Pulmonary, Allergy, Critical Care and Sleep Medicine, Director for the UAHS Center of Sleep & Circadian Science, and Medical Director for the Center for Sleep Disorders at the University of Arizona. His current research is supported by the NIH/NHLBI, PCORI, American Sleep Medicine Foundation and industry funding. Dr. Parthasarathy is the immediate past-chair for the Sleep Research Network and previously served as Chairman of the Sleep Disorders Research Advisory Board to the NIH. Currently, he serves as an Associate Editor for the Journal of Clinical Sleep Medicine and as an editorial board member of the American Journal of Respiratory and Critical Care Medicine. His research focuses on sleep and breathing in both ambulatory and critically ill patients. Specifically, his current PCORI-funded initiative is addressing peer-driven intervention for promotion of CPAP adherence. His NIH-funded research investigates the role of predictive analytics for detecting sleep-disordered breathing in community-based populations and a training program for underrepresented minorities in lung and sleep apnea research. His PCORI funded studies involve implementation science in sleep apnea. He currently is assisting the NIH as a consultant to develop its next 5-year strategic plan related to sleep medicine research. He is committed to training and fostering young scientific investigators in the pursuit of sleep and circadian science.
