My current research revolves around four main questions:

1. Ethnic diversity and social cohesiveness: How does growing ethnic diversity affect societies' social cohesiveness? I have recently published a review and meta-analysis on this topic with Peter Dinesen (KU Political Science) and Kim Sønderskov (Aarhus University).
   
2. Perceived and actual discrimination: Why do claims about the pervasiveness of discrimination seem to intensify as western societies increase equality and liberty with regards to immigrant minorities? To answer this question, I am conducting online trust games among a large representative sample of the German population. This research is part of my APAX project, which is funded by the German Research Council (DFG). A second project, funded by the Carlsberg Foundation, uses survey experiments to study misperceptions of the extent of discrimination among mainstream majority Danes.
3. Ethnic residential segregation: How do immigrants and their descendants fare in mainstream suburbs? In the WELLMOB project, which is also funded by the DFG, Sarah Carol (UC Dublin), Jonas Wiedner (WZB Berlin Social Science Center), and I are investigating the internal migration of persons of immigrant origin and how they fare in terms of subjective wellbeing when they move to mainstream suburbs.
4. Comparative research: How can we perform valid and reliable statistical multilevel analysis of small cluster samples? I have recently published an article on this topic with Martin Elff (Zeppelin University), Jan Paul Heisig (WZB Berlin Social Science Center), and Susumu Shikano (University of Konstanz) in the British Journal of Political Science.

At KU's Department of Sociology I am teaching statistical methods, courses on race, ethnicity and discrimination, and theory-guided introductions to Sociology. Currently I teach:

• Multiple Regression and Fundamentals of Causal Inference
• Sociolodgy of Discrimination
