I am head of an Emmy Noether junior research group at the University of Bonn. My research focuses on urban sociology, social networks, and the origins and consequences of segregation. It is driven by the question of how social structures operate behind the backs of those involved. In this context, I have mainly worked on three topics:

    1. Neighbourhoods and immigrant incorporation,
    2. Ethnic segregation in secondary schools,
    3. Social boundaries in local contexts and networks. Read more…

In my newly established research group, “Sorting Decisions and Peer Processes in Schools (SPINS),” we study how school administrators’ and teachers’ choices about classroom placements affect students’ peer processes in German secondary schools. The research group is funded by the German Research Foundation.

Theoretically, my work tries to bridge the gap between structuralist views of sorting processes and subjectivist perspectives on their consequences for people’s everyday lives. To test these ideas empirically, I usually rely on a combination of different quantitative data (e.g., survey/administrative/spatial data) and methods (e.g., network, multilevel, and panel analyses).

In the past, I worked as an assistant professor at the University of Amsterdam and as a postdoc at the University of Cologne. I obtained my doctoral degree at the University of Mannheim. I have co-directed a research project on the “Structural Origins of Separate School Lives (SEPLIVES)” and have been involved in the ERC project “Social Integration and Boundary Making in Adolescence (SOCIALBOND)” as well as in the “Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU).”
