Dr. Graupensperger is an Acting Assistant Professor in the Center for the Study of Health and Risk Behavior at the University of Washington - School of Medicine. His research focuses on peer influences in social groups, such as sport teams, and how these group dynamics shape individuals’ behaviors in both constructive and pernicious ways. For example, his research has shown that positively identifying with a team and feeling a sense of belonging and support is a protective factor for athletes’ mental health, but also that tight-knit teams may entail stronger social pressures to conform to risky behaviors such as alcohol use. Dr. Graupensperger’s research also examines the interrelated nature of mental health and substance use among adolescents and young adults.
