Noya Kislev, Graduate student
I am a PhD student in social psychology at the IDC Herzliya, supervised by Tamar Saguy. I received my B.A. in Psychology and M.A. in Social Psychology from IDC Herzliya. My research interests include gender stereotypes, gender development among children and gender-typing processes induced by parents, environment and culture. In particular, I am interested in effective ways to change gender-typing of children.
Hanna Szekeres, Graduate Student
My general research interests are different aspects of intergroup relations, particularly involving groups in conflict (e.g., the Israeli-Palestinian conflict), minority and majority members in a society (e.g., the Roma and non-Roma in Eastern Europe, African Americans or Muslims and Whites in the U.S.), or gender norms. In my dissertation research, I investigate the psychological and intergroup processes that underlie the phenomenon of witnessing and (not) confronting prejudice and discrimination as a bystander.

Siwar Aslih, Graduate Student
I am currently a Ph.D student at the University of Groningen and the IDC Herzliya, supervised by Martijn van Zomeren, Eran Halperin and Tamar Saguy. I received my dual-major B.A. in Psychology and Educational counseling and my M.A. in group counseling from University of Haifa. My main areas of interest are collective action, power relations embedded in intergroup conflicts, and collective emotions and beliefs. My PhD project investigates emotions and emotion regulation in collective action in the context of intractable conflicts with a power relations perspective.
Aharon Levy, Post-doctoral fellow
Aharon Levy is a Research and Teaching Fellow at the Columbia Business School Management division. Aharon's research examines psychology as a means for the promotion of social change. Specifically, Aharon studies the potential of Gateway Groups to improve intergroup relations, and the development of psychological interventions for intergroup conflict resolution. Additionally, Aharon also studies the role information plays in distributive negotiations. Apart from his research, Aharon also teaches courses on psychology & social change, and consults organizations in the field of intergroup relations.

Eric Shuman, Phd Student
I am a PhD student in social psychology at the University of Groningen supervised by Tamar Saguy, Eran Halperin, and Martijn van Zomeren. I received a B.S. in Psychology and a B.A. in Global Politics from Washington and Lee University in 2014, and completed my M.A. in Social Psychology at the IDC Herzliya. My research interests include collective action and emotions, and power relations in conflict. In particular, I am interested in different types of collective action (e.g. nonviolent, nonnormative, violent). My research examines psychological factors that promote support for these types of action, but also the effects and effectiveness of these types of action at motivating the high power group to address inequality and pursue conflict resolution.
