Stephanie D. Preston is a professor in the Department of Psychology at the University of Michigan. She has a master’s degree and a PhD in behavioral neuroscience from the University of California at Berkeley, where she studied the neurobiology and behavior of decisions in food-storing animals. Subsequently, she held a postdoctoral fellowship at the Department of Neurology at the University of Iowa College of Medicine to study how the brain supports emotion-based decisions in humans. Stephanie’s research is interdisciplinary in focus and methods to address how the brain evolved to support complex behavior at the intersection of emotion and decision making. One focus is on empathy and altruism, particularly how others’ states impact our own and motivate helping. Another focus is on decisions about resources, such as food, money, material goods, and charitable gifts, to address issues surrounding consumerism, hoarding, and pro-environmental behavior. She is currently fusing her lines of research to determine how best to promote altruism and charitable giving across racial and political divides and for other species and the natural environment, including collaborations with corporations and non-profit organizations.
