Past Students

Rezarta Bilali

Rezarta holds a Master's degree in Conflict Resolution from Sabanci University in Turkey.  Rezarta is conducting research in Rwanda and Burundi assessing Tutsis' and Hutus' attitudes toward each other, willingness to interact, and their knowledge on origins of mass violence as an academic consultant to the La Benevolencija Rwanda reconciliation radio project.  She has conducted research on youth conflict resolution programs for Greek and Turkish Cypriots, as well as our attitudes about, and the relationships between, different types of trust in Albanian and U.S. student populations.

Rezarta’s research focuses on the relationship between collective memories and construction of social identities, and received a Harry Frank Guggenheim Dissertation Award Award to support her while conducting this research. Rezarta completed her Ph.D. in Spring 2009 and took a position in Fall 2009 at University of Massachusetts Boston, as Assistant Professor, Dispute Resolution Programs, McCormack Graduate School of Policy Studies.

Daniel Chapman

Daniel Chapman received his BA in both Psychology and Government & Political Affairs in 2013 from Millersville University. He received his PhD in Summer 2018 from our program. He is a post-doctoral fellow at the Annenberg Public Policy Center at the University of Pennsylvania and a research fellow in the Yale Law School. 

As an undergraduate he conducted a number of research projects on how different types of psychological threat influence public policy preferences. He also served as a research assistant for an initiative in Millersville University’s Center for Disaster Research and Education involving academic institutions in four countries seeking to collaborate on topics related to natural disaster risk reduction and resiliency.

Daniel’s current interests fall broadly at an intersection between social psychology, environmental conservation, and international relations. In one area of research he is exploring psychological factors that affect adaptive responses to resource scarcity, environmental conflict, and projected climate change impacts. One current focus of this work is to develop frameworks of individual and group-level processes related to risk perceptions, resource management, adaptive capacity and disaster resiliency. His research also examines how individuals prepare and respond, both individually and collectively, to large-scale disaster events and instances of localized environmental degradation. He also has additional research interests in the role of emotions in conflict resolution and methods for improving the effectiveness of post-conflict justice procedures.

Given the complexity and multidimensionality of these issues, he is actively engaging in and pursuing further interdisciplinary collaborations with researchers in environmental conservation, sociology, political science, and marine science, among others.

Manisha Gupta

Manisha obtained a B.S. in Business Administration, and a B.A. in Social Welfare, from the University of California at Berkeley before joining the program at UMass. During graduate school, the majority of her research focused on investigating antecedents and consequences of prejudice between ethnic minority groups, and methods of improving cross-ethnic coalition building, for which she was awarded a National Science Foundation Graduate Research Fellowship.

Manisha will begin The Jacquelin Goldman Congressional Fellowship from the American Psychological Association starting in September, 2015. This provides psychologists with an interest in policies that affect the psychological development of children with an invaluable public policy learning experience; to contribute to the more effective use of psychological knowledge in government; and to broaden awareness about the value of psychology-government interaction among psychologists and within the federal government.

Helen O'Hara

Helen received her Masters in Violence, Terrorism and Security from Queen’s University, Belfast. Her thesis utilized a meta-analysis of approaches to analysing terrorist psychology in order to understand the cognitive evolution of an extremist—from initial experiences of political grievances to committing a violent act. During this time she conducted field research into insurgent tactics in Northern Ireland as part of a partnership with the University of California Institute of Global Conflict and Cooperation. She has also worked at the UK’s leading children’s charity, Barnardo’s, policy and research department investigating child exploitation.

Helen’s current interests focus on the nature of morality and political violence, in particular the social and psychological factors which influence engagement with, and justification of, terrorism or alternative nonviolent social change. She is hoping that this research will lead to practical applications for peacebuilding and conflict transformation. She received her Masters from our program in 2015.

Seyyed Nima Orazani

Nima received a Master of Science in General Psychology in 2010 from Guilan University in Iran. His current research interests are in collective action, intergroup processes, and social psychology of rights and duties. His most recent research is focused on two areas, explaining advantages and even possible disadvantages of adopting nonviolent strategies in political context compared to violent strategies, and examining the effects of a right-focused mindset vs. duty-focused mindset on social justice and prosocial behaviors. He hopes in light of his research he can find some effective ways to increase people's participation in promoting social justice in the society as individuals in general and help activists to eschew costly strategies and adopt tactics that are more efficacious to promote democracy.

Hema Preya Selvanathan

Hema received her PhD in May, 2019 and is currently a post doctoral fellow at the University of Queensland in Brisbane, Australia. Her BA was in Psychology from the University of Wisconsin, Eau Claire in 2014. Hema’s research focuses on collective action and intergroup contact for social change. Specifically, she investigates three interrelated questions: 1) what are the factors that motivate participation in collective action? 2) how do people respond to efforts for social change? and 3) how can intergroup contact be utilized to promote social justice? To answer these questions, she continues to learn various techniques, including quantitative and qualitative methods, with cross-sectional, experimental, and longitudinal designs in both laboratory and field settings. She hopes to apply her work to promote equality and justice in society.

Rachel Steele

Rachel received her Ph.D. in 2016. She also holds a Master’s in Peace and Justice Studies from the University of San Diego. Prior to joining the Psychology of Peace and Violence Program at UMass she worked at the United States Institute of Peace for three years addressing governance and legal issues in Iraq and post-conflict justice and reconciliation in a variety of settings. She had also worked as a peace activist in Seattle and in the Philippines (with the Mennonite Central Committee) working alongside local peace-builders.

Currently, Rachel is a Visiting Assistant Professor of Psychology at Hampshire College (2016-2017) teaching social psychology courses. Rachel has conducted two integrated lines of research on emotional and cognitive responses to intergroup provocations and to attempts at intergroup reconciliation. For example, her research has examined responses to terrorism and to undocumented immigrants in the U.S. Her dissertation research focused on beliefs of victim group members and perpetrator group members about reconciliation efforts made by the government (in Chile for political and racial violence and in the U.S. for a racial injustice). 

Ramila Usoof-Thowfeek

Ramila received her Ph.D. from the University of Massachusetts Amherst in Psychology. Currently, she is  faculty member in the Department of Philosophy & Psychology at the University of Peradeniya in Sri Lanka. She was a research scholar at the Solomon Asch Center for the study of Ethnopolitical conflict at the University of Pennsylvania in 2004-2005 and is also a trained mediator. Her research focuses on how individuals are able to maintain the perception that they are moral, despite having committed moral transgressions.

She also studies how different mechanisms are used in moral judgments depending on whether the transgression is interpersonal in nature or takes place on behalf of a group in an intergroup context. In addition, Ramila was interested in creating psychosocial intervention programs, which are culturally specific, for those affected by intergroup violence. Along this line, she conducted research in Sri Lanka looking at the influence of religious beliefs and practice on psychological resilience.
