Senior Research Associates

Orly Idan

I am currently a lecturer (adjunct) at the Interdisciplinary Center (IDC) Herzeliya, teaching psycholinguistics; language, emotion and conflict; and academic research and writing; and a senior research associate at the Psychology of Intergroup Conflict and Reconciliation Lab at the Baruch Ivcher School of Psychology at IDC, and at the Martin Springer Center for Conflict Studies at Ben Gurion University of the Negev. My current research interests are the effect of linguistic cues on generating emotions within the context of intractable conflicts; discourse analysis of students' encounters with narratives of the other; mentalization and language development; resilience sources; and, salutogenic interventions in conflictual settings. I was a postdoctoral associate at the Conflict Management Program at Ben Gurion University, focusing on a sense of coherence-based assessment aimed at evaluating an acute psychiatric in-patient unit's needs and development of an intervention program. My dissertation from Tel Aviv University focused on resilience sources, socio-emotional self-perceptions, family climate, and hopeful thinking among students (advisor: Prof. Malka Margalit). I completed my M.A. degree in psycholinguistics (advisors: Prof. Avner Ziv and Prof. Elite Olshtein) at Tel Aviv University.

Rodayna Badir

I am a  Social-Political activist with the Federation movement in Israel. Currently, I am a postdoctoral fellow at the PICR Lab working under the guidance of Prof. Eran Halperin at the Hebrew University.

My main area of interest is the intergroup identity and intergroup relations. Hence, my PhD examines the integration of the Arab traditional society in the modern Israeli society, focusing mostly on the influence of women empowerment values at Bar-Ilan University.

In addition, I give lectures on education at the Kiryat Ono academic college.

Oded Adomi Leshem

I received my Ph.D. from the School for Conflict Analysis and Resolution (S-CAR) at George Mason University and am presently a visiting scholar at S-CAR and a postdoctoral fellow at the PICR Lab working under the guidance of Prof. Eran Halperin. My research is located at the nexus of political psychology and conflict resolution with a specialization in protracted ethnonational conflicts. I study hope, fear, and perceptions of competition among citizens engulfed in intractable conflicts with the aim of revealing how these emotions and beliefs affect the dynamics of violent intergroup conflict. My main areas of interests are international and intranational conflicts, the formation and transformation of political attitudes and ideologies, and conflict and the media. Apart from my focus on advancing theories in conflict resolution and political psychology, a key aspect of my research agenda is to design and test conflict interventions aimed at transforming violent conflicts. [personal page]

Anna Stefaniak

I received a Ph.D. in psychology with honors from the University of Warsaw, Poland in 2017 and completed a post-doctoral fellowship at Loyola University Chicago (with Prof. Robyn Mallett, 2017-2018). Since 2018, I have been working as a post-doctoral fellow at Carleton University in Ottawa (with prof. Michael Wohl) and recently joined the PICR Lab as a part-time post-doctoral fellow.

My work is in the area of social psychology of intergroup relations. In my research I focuses on: (1) reduction of intergroup bias through direct and indirect intergroup contact; (2) the role of collective emotions and ways in which people relate to the history of their social groups in shaping current intergroup attitudes; and (3) the psychological underpinnings of negative and positive intergroup behavior, e.g., hate crime, collective violence, and collective action.

Neomi Frisch-Aviram

I received my Ph.D. in public policy and administration from The University of Haifa in 2019. I have an M.A degree in political science from the Hebrew University and a B.A degree in sociology and Jewish philosophy from the Hebrew University. In my dissertation, I studied street-level policy entrepreneurship training in public organizations in collaboration with the Israeli Health Ministry. In the last year, I was awarded a Fulbright Postdoctoral Fellowship to pursue my research project titled “Street Level Identities: Exploring Street Level Worker's Identity from a Micro, Meso, and Macro-Level Perspective" at The University of Chicago. I am very much interested in the intersection between public policy and administration and conflict and reconciliation theories.
At PICR Lab at the Hebrew University, under the guidance of Prof. Eran Halperin, I'm working on a project which investigates the relationship between policy communication and citizens' policy compliance during the Covid-19 pandemic. As a former manager in the Israeli public sector, I aim to help policy makers and public administration managers as they work to construct programs and policies for preparing and maintaining high-quality public service, both by understanding street-level motives and behavior, and by analyzing different communication and implementation strategies.
