prof. dr. T.T. (Tom) Postmes

Full Professor, Social Psychology



Tom Postmes (PhD, 1997, University of Amsterdam) studies human behavior in virtual groups and communities, in crowds and also in organizations and "normal" teams. A major theme in his work how individual actions, thoughts and social interactions become co-ordinated, in such a way that people act and think as a team, a group, an organization or as a society. In chaotic, unusual or unexpected situations (a demonstration, a disaster but also online) a process of self-organisation takes place. We can learn a lot from this and it raises questions about group dynamics in “normal” groups and everyday life. Central to a lot of his work is the influence of personal and social identity: the relation of the individual to the group.

Tom became a professor of Social Psychology at the University of Exeter in 2004. Since returning to The Netherlands in 2007, he is the chair of Social Psychology at the University of Groningen. He received various awards from august institutions such as the Royal Netherlands Academy of Arts and Sciences (KNAW), the Dutch National Science Foundation (NWO), the Economic and Social Research Council (UK) and National Science Foundation (USA). In recent years, he has collaborated with various ministries on research projects concerned with societal discontent and social unrest in The Netherlands. He also studies the societal impact of induced earthquakes in Groningen, and is Scientific Director of the knowledge platform (Kennisplatform Leefbaar en Kansrijk Groningen, in Dutch) that seeks to integrate knowledge about this and promote its application.
