Dr. Leung is the director of the Perioperative Medicine Research Group based at the University of San Francisco, Parnassus site. The group conducts outcomes research in older surgical patients. Our recent work focuses on identifying the pathophysiology of postoperative delirium and cognitive decline using prospective cohort studies and randomized controlled trials.
