Current Graduate and Postdoctoral Researchers

Trisha Dehrone

Trisha Dehrone received her B.A. in Psychology from Rutgers University – Newark and a M.Sc. in Social Psychology from UMass Amherst. She is currently completing her PhD in the UMass Psychology of Peace and Violence Program, with support from a National Science Foundation Graduate Research Fellowship.  She became interested in improving intergroup relations and advancing social justice as an intern in the White House's Office of Presidential Correspondence, managing casework for constituents interfacing with U.S. Citizenship and Immigration Services (USCIS) and the Department of Justice (DOJ) on a range of immigration and discrimination cases. Her research examines how people experience and navigate interactions with members of other social groups. She is specifically interested in understanding the factors that may serve as barriers to or facilitate greater authenticity during these encounters, and whether cultivating greater authenticity may relate to greater feelings of intergroup closeness and empowerment. She has designed and evaluated interventions to bridge group differences, including in the U.S., Rwanda, and Bosnia and Herzegovina. During her graduate years, she also served as an intern with the Center for Inclusion and Belonging at the American Immigration Council and with the United Nations committee of the Society for the Psychological Study of Social Issues.

Liora is a PhD student in the Psychology of Peace and Violence program at the University of Massachusetts Amherst. She received her B.A. in psychology and international relations at Brown University and M.A. in conflict mediation at the University of Barcelona. Liora is broadly interested in investigating the behavioral underpinnings of social-political conflicts and finding interventions informed by social psychology to improve group relations. She is conducting both experimental and applied research on intergroup contact. She is specifically interested in the social categorization process, as well as in perception of multiple social identities and negative experiences during intergroup contact. She has worked with non-governmental organizations like the Trust for Public Land and International Organization for Migration (IOM) to implement and evaluate contact interventions. She is the co-author of the toolkit, Designing, Implementing, and Evaluating Impact of Social Mixing Programs, and contributed to developing its corresponding e-course for IOM.

Past Graduate and Postdoctoral Researchers

Cierra Abellera

Cierra Abellera was a beloved 5th year graduate student in the Department of Psychological and Brain Sciences, when she passed away tragically in November 2023. After attending a community college in Hawaii, Cierra received her bachelor’s degree from Boise State University with the university’s highest honors (Summa Cum Laude). Cierra enrolled in the PhD program at UMass Amherst in 2019 to study intergroup relations, with a particular interest in cultivating feelings of belonging and inclusion among refugee communities and among members of minoritized racial and ethnic groups. During her years in our graduate program, Cierra held research internships with Perception Institute and the Migration Policy Institute, and she received the Applied Social Issues Internship Award from the Society for the Psychological Study of Social Issues, to fund a project she initiated with Hello Neighbor, through which she developed and analyzed surveys to assess refugees’ understanding and experiences of race and racism within their new context of the United States. Cierra also collaborated with Dr. Meta van der Linden on the EUR Bridge Project, a multi-wave survey examining the views and experiences of newly resettled Syrian refugees in the Netherlands, to learn what contributes to their feelings of belonging and sense of home. Cierra was a Yale Ciencia Academy Scholar, and a participant in Stanford University’s PRISM program, both designed to equip doctoral students from underrepresented backgrounds with skills and networks to prepare them for postdoctoral research positions.

Beyond all her academic achievements and accomplishments, Cierra also touched the hearts of all who knew her.

Rezarta Bilali

Rezarta Bilali received her PhD in social psychology, with a doctoral concentration in the psychology of peace and violence, from the University of Massachusetts Amherst in 2009. She received her BA in psychology from Bogazici University, and a masters’ degree in conflict resolution at Sabanci University, both in Istanbul, Turkey. Her research focuses on the social psychological underpinnings of intergroup conflict and violence in various conflict settings, including in Albania, Burundi, Burkina Faso, Democratic Republic of Congo, Rwanda, Turkey, and the U.S.). She merges theory and practice by working with non-governmental organizations to develop and evaluate violence prevention and reconciliation media programs. The broader goal of this work is to generate knowledge that successfully informs practice and social policy on prevention of intergroup violence and promotion of positive intergroup relations. To achieve this goal, she 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. Her research has been supported by numerous foundations including USAID, Harry Frank Guggenheim Foundation, American Psychological Foundation, International Peace Research Association, Psychology Beyond Borders, and Society for the Psychological Study of Social Issues. Rezarta is now an Associate Professor of Psychology and Social Intervention at New York University; prior to joining the NYU faculty, Rezarta was an Assistant Professor of Conflict Resolution at the University of Massachusetts Boston.
