I am a Research Associate in Mathematics at the University of Cambridge in the group of Oscar RandalWilliams. Previously, I was at the University of Copenhagen where I finished my PhD in October 2018.

Research interests
Algebraic and Geometric Topology, in particular: topology of moduli spaces, manifold bundles and their characteristic classes, automorphism and embedding spaces of manifolds, mapping class groups, surgery theory, cobordism categories, and configuration spaces. My side interests include the cohomology of arithmetic groups, Ktheory, and (computational) stable and unstable homotopy theory.
For further information, see my CV.
