We are happy to announce that Eran has been awarded one of the prestigious ERC Consolidator Grants (almost 2 million Euros) – among the most competitive funding schemes of the European Research Council. 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.
