My work aims to better understand the social psychological processes that lead to social justice and peace on one hand and to prejudice and violence in and between societies on the other. I endorse an approach to social psychology that is ultimately concerned with building more peaceful and socially just societies in which pressing social issues are dealt with in constructive and non-violent ways, and that takes into account the multi-layered nature of social psychological phenomena with individual, group, and societal-level dimensions. This requires the use of multiple methods; recently, I have started to use Q methodology as a method that combines qualitative and quantitative features.

My research has focused on topics such ideology, intergroup conflict, authoritarianism, prejudice, and political attitudes, as well as, more generally, social psychological approaches to peace and conflict.
