Research Interests

My research falls into the area of comparative welfare state research. More specifically, I am doing research on labor market policies. While my doctoral and pre-doctoral research was concerned with how and why labor market policies have become more "activating" or "employment-friendly", my post-doctoral research focuses on the effects of activation policies.

Research Interests
My research is at the intersection of international relations, conflict studies, and political sociology. Eastern and southern Africa, especially the Democratic Republic of Congo, are my areas of geographic specialization. In the Congo, I have conducted research on humanitarian military intervention, armed groups, and local structures of rule. More recently, I became interested in the dynamics between collective contentious action and forms of internationalized authority. My teaching and research interests also include development cooperation, sovereign debt politics, and post-conflict statebuilding.
