His research focuses on political psychology and political communication. He is currently working on a research project investigating the influences of political scandals on citizens’ perceptions and political evaluations. Furthermore, his research deals with the effects of cross-cutting news exposure on political participation and he investigates how terrorism news affect public opinion, emotional reactions (i.e., fear and anger), intergroup relations, policy preferences, and political attitudes. In a recently funded project he examines the role of social media for anti-Semitic attitudes and anti-Israel views in Germany.
