Sucharita Belavadi, a former Social Identity Lab member and postdoc, is currently an Assistant Professor of Psychology at Liverpool Hope University in the UK 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.

Amber Gaffney is a former Social Identity Lab member and postdoc and currently an Associate Professor of Social Psychology at Humboldt State University. She is also an Associate Editor for Group Processes and Intergroup Relations and for the Journal of Applied Social Psychology. She studies how prototypical and non-prototypical group members create and manage uncertainty to enact social change. Amber is also interested in social comparison processes and in social identity and uncertainty dynamics in the political sphere.

Fiona Grant, a former Social Identity Lab member and postdoc, is an Assistant Professor of Social Psychology at the University of Mauritius. She studies social identity processes in health contexts, specifically the role of group membership in health promotion and exercise behavior.
