PhD. Is a Senior Lecturer in the Program in Conflict Management and Mediation at Tel Aviv University. He received his PhD in social psychology at Tel Aviv University in 2019. Between 2018 and 2020 he was a Postdoctoral Fellow in the Peace and Conflict Neuroscience Lab at the University of Pennsylvania, and Postdoctoral Innovation Lab Fellow at Beyond Conflict. His research consists of an examination of different psychological barriers to attitude change and conflict resolution (e.g., victimhood), and the development of psychological interventions (e.g., paradoxical thinking) to address these barriers and promote better intergroup relations and conflict resolution. Dr. Hameiri employs a mixed-method approach with various qualitative and quantitative methods (e.g., intervention tournaments), in the lab and on a large-scale in the field; working in various contexts and populations worldwide, in collaboration with a broad community of international collaborators, as well as NGOs, advertising and media experts.

Rezarta Bilali

Rezarta Bilali received her PhD in social psychology with a concentration in peace and violence from the University of Massachusetts at Amherst. Her research focuses on the social psychological underpinnings of intergroup conflict and violence in various conflict settings (e.g., Albania, Burundi, Burkina Faso, Democratic Republic of Congo, Rwanda, Turkey, the U.S.). In one line of research, Dr. Bilali seeks to understand the influence of group identities on intergroup conflict, and the psychological underpinnings of conflict narratives, specifically focusing on group members' denial or acknowledgement of past collective violence, the factors that drive denial narratives, and strategies to address these narratives. In another line of research, she merges theory and practice by working with non-governmental organizations to develop and evaluate violence prevention and reconciliation media programs. The goal of this research is to generate knowledge that successfully informs practice and social policy on prevention of intergroup violence and promotion of positive intergroup relations. In order to achieve this goal, Dr. Bilali contextualizes her research in real world settings, uses multiple methodologies (e.g., experiments, surveys, interviews, content analysis of written materials), considers historical and structural variables, and engages practitioners in her work. Dr. Bilali’s research has been supported by numerous foundations including USAID, Harry Frank Guggenheim Foundation, American Psychological Foundation, International Peace Research Association, Psychology Beyond Borders, Society for the Psychological Study of Social Issues. Bilali graduated with a BA in Psychology from Bogazici University, and a Masters’ degree in Conflict Resolution at Sabanci University, both in Istanbul. Prior to joining NYU, she worked as an Assistant Professor of Conflict Resolution at the University of Massachusetts, Boston.
