Harry Reis is Professor of Clinical and Social Science in Psychology at the University of Rochester. His research interests involve social interaction and close relationships. Reis studies the factors that influence the quantity and closeness of social interaction, and the consequences of different patterns of socializing for health and psychological well-being. In his research, subjects keep detailed records on their on-going social interaction. These are tabulated by computer and related to various factors such as sex role, health, and emotional well-being. Reis is also investigating some of the psychological processes that affect the course and conduct of close relationships. He is particularly interested in intimacy, attachment, and emotion regulation.
