I am a research postdoc at the Max Planck Institute for Mathematics. I have recently finished my PhD at Utrecht University under the advisement of Ieke Moerdijk. My thesis was entitled "Categorical Properties of Topological and Differentiable Stacks". Some of my current research is in this or similar areas, but I am also branching out into derived geometry, and higher stacks. Furthermore, I have an interest in (higher) operads / Dendroidal sets.
