I am a postdoc with Claudia Scheimbauer at the Technical University of Munich and a member of the SFB Higher Invariants Collaborative Research Centre.

My research lies at the intersection of category theory and quantum field theory. I use and develop categorical tools to study domain walls and defects in topological quantum field theory.

I completed my PhD at the University of Texas at Austin in August 2024 under the supervision of Dan Freed. You can find a copy of my thesis here.
