I am a Full Professor for Psychological Methods and Evaluation at the University. I received my PhD in Social Psychology from the University in Marburg, Germany, in 2005 and worked as a Lecturer in Social Psychology and Senior Lecturer in Psychological Methods at the same university before moving to the University in Hagen in 2015. In 2011/2012, I was a visiting researcher at the universities of Oxford, UK and St Andrews, UK.

Description of research

In my research, I focus on intergroup relations, especially on the central question on how to bring different groups into contact and thus, how to improve intergroup relations and to reduce conflict between groups. My research is mainly inspired by intergroup contact theory and I have recently started to examine the joined effects of intergroup contact and social norms on tolerance and cooperation on multiple levels of analysis (i.e., the individual and contextual level). In my research, I use a mixture of quantitative methods ranging from experiments in the lab and online to representative survey data using advanced statistical modeling techniques.
As such, I have also published on general methodological issues in intergroup contact research as well as statistical methods relevant for survey research (e.g., structural equation modelling and multilevel modelling).
