Lab Manager

Matthew Burt

Matthew Burt (goes by MattB) focuses, through the lens of social identity theory and contact theory, on the use of funny language and humor in bias reduction. He is interested in how witnessing or imagining a humorous interaction between in- and out-group members (or leaders) can lead uncertain individuals to reach across the aisle and encourage meaningful contact with others, as well as how funny individuals can use humor to place themselves in leader positions within their groups.

Postdoctoral and Professorial Affiliates

Xiang Ao

Xiang Ao is a former Social Identity lab member, and is currently an assistant professor at Adams State University in Colorado. He investigates how group members respond towards various types of ingroup deviance, how identity threats trigger group members’ negative sentiment towards immigrants and outgroups, and the role of social identities in collective mobilization and protest in culturally diverse regions (e.g., Hong Kong).

Sucharita Belavadi

Sucharita Belavadi is a former Social Identity Lab member and postdoc, and is currently an Assistant Professor at Flame University in Pune, India (https://flame.edu.in/faculty/sucharita-belavadi/). She investigates self-uncertainty processes in intergroup conflicts, especially in the context of Indian religious and language-based groups. Of particular interest is how groups perceive marginal ingroup members within the context of language and social identity. She also examines how groups engage in a narrative of competitive victimhood during intergroup conflict.

Kaiyuan (KY) Chen

Kaiyuan (KY) Chen, a former social identity lab manager, is currently a Postdoctoral Research Fellow at the University of Salzburg, Austria.

Amber Gaffney is a former Social Identity Lab member and postdoc and currently an Associate Professor of Social Psychology at California Polytechnic University Humboldt. She is also an Associate Editor for Group Processes and Intergroup Relations and for the Journal of Applied Social Psychology.

David Rast

David Rast is a former lab member and is currently an Associate Professor of social psychology at the University of Alberta in Edmonton, Canada. He is a former Associate Editor of the Journal of Applied Social Psychology. He examines when non-prototypical leaders become influential and how leaders transcend conflict-charged intergroup relations.

Viviane Seyranian

Viviane Seyranian is a former lab member and an Associate Professor of Psychology at California Polytechnic State University, Pomona. Her research examines the role of communication tactics and source types (e.g., majorities-minorities) on attitudes, emotions, and behaviors. Viviane is testing a theory called social identity framing, which outlines communication tactics related to social identity change.

Joey Wagoner

Joey Wagoner, a former lab member and postdoc, is currently an Assistant Professor in the Department of Psychology at the University of Colorado, Colorado Springs.
