I am assistant WISO_Ellwardt1professor at the University of Cologne in Germany since 2014. I am affiliated with the Institute of Sociology and Social Psychology (ISS) as well as with the CGS Cologne Graduate School in Economics, Management and Social Sciences (CGS).

Prior to my current position, I spent eight years at the Interuniversity Center for Social Science Theory and Methodology  (ICS) at the University of Groningen (RUG) in the Netherlands, where I received my PhD in Sociology in 2011. After my PhD, I continued working there as postdoctoral researcher and lecturer.

My research focuses on the relationship between social networks and well-being. Within this framework, I pursue two research lines: First, I study informal networks in organizations. Second, I investigate personal networks and health of older adults. Much of this work involves the application of advanced quantitative methods and has been published in high-ranking international journals.

I am board member of the German research division on social networks (DFG Sektion Soziologische Netzwerkforschung), and member of the DFG-founded German network SoNegU of research on social networks and inequalities in health.
