In his research, he focuses on the one hand on how the embeddedness of regulators in financial markets shapes their evolution, in particular with respect to the shadow banking sector (Thiemann and Lepoutre, forthcoming. American Journal of Sociology). On the other hand, he inquires into the evolution of the regulation of systemic risk post-crisis from a sociology of knowledge perspective, asking if and in how far academic economists inform the regulation of this phenomenon after the crisis. He has received grants from the Volkswagen Foundation, the Institute for New Economic Thinking as well as the Center for Sustainable Architecture of Finance in Europe for his work.
