William Olds has an undergraduate degree from University of Michigan and is working on his graduate degree at Yale University, New Haven, Connecticut, USA, in the laboratory of Tian Xu. His current research focuses on satiety signals from the gut and how that communication to the brain breaks down in the pathogenesis of obesity.
