I'm interested in the higher category theory behind (fully extended) Topological Quantum Field Theory. My current research focus is on the notion of 'reflection positivity' for TQFTs introduced by Freed and Hopkins in arXiv:1604.06527. This lead me to thinking about equivariant stable homotopy theory and more generally stable equivariant $\infty$-categories. Related to that I am also interested in K-Theory.
