Dr. William (Bill) Chopik examines how close relationships—and the people in them—change over time and across situations. His research focuses on how factors both inside (biological, hormonal) and outside (social roles, geography) of people influence their approach to social relationships. This approach encompasses phenomena as broad as how relationships and social institutions shape development and as focused as the mechanisms that underlie the link between close relationships and health.
