Principal Investigator
David Rast, III, Director

David is an assistant professor of social psychology and leadership at the University of Alberta. David has two primary lines of research drawing extensively on social identity and self-categorization theories, as well as related subtheories. First, he is interested in understanding how leaders elicit or incite social and organizational change by going against their group’s norms. Second, he is interested in understanding how leaders can bridge profound intergroup divisions to build a unified no identity and achieve a joint goal. Other lines of research are related to these two themes, exploring the processes and implications of political identity, minority influence, deviance, intergroup cooperation/conflict, leader rhetoric, and organizational behavior. David’s work is generously supported by the Social Sciences and Humanities Research Council of Canada (SSHRC).
David completed his PhD and Master’s at Claremont Graduate University (USA) during which time he was a Predoctoral Research Fellow for the U.S. Army Research Institute’s Leader Development Research Unit at Fort Leavenworth in Kansas (USA). Prior to joining the Department of Psychology at the University of Alberta in 2015, he was an assistant professor at the University of Sheffield’s Institute of Work Psychology (UK). David currently serves as Associate Editor for the Journal of Applied Social Psychology, Consulting Editor for Group Processes and Intergroup Relations, and is appointed to the Editorial Boards of Self and Identity and the Journal of Theoretical Social Psychology. In 2018, David was elected as a Fellow of the Society for Experimental Social Psychology.
