Congratulations​ to Prof. Eran Halperin, Prof. Eric Knowles & Eric Shuman for receiving the BSF grant for their work on understanding what kinds of collective action can be effective in advancing social change!


Congrats to Prof. Halperin, Dr. Roni Porat & Kinneret Endevelt for receiving the ISF grant for their proposed research to uncover the influence of institutional changes that signal inclusion on disadvantaged students’ sense of belonging, academic achievements, and retention rates.

We are happy to announce that Eran has been awarded one of the prestigious ERC Consolidator Grants (almost 2 million Euros). The research funded by that grant is aimed at identifying novel mechanisms by which different intergroup interventions influence different individuals, i.e., creating an innovative framework for personalized intergroup interventions.
