Dr. Tashi Walde

I was a postdoc at TUM working with Claudia Scheimbauer. Before that I wrote my Ph.D. thesis On the theory of higher Segal spaces at the University of Bonn under the supervision of Catharina Stroppel and Tobias Dyckerhoff.

My research interests include higher category theory, homotopy type theory, homotopical and homological algebra and their applications to representation theory, categorification and topological field theories.

Between 01.04.2022 and 31.12.2025 I was a member of the SFB 1085 Higher Invariants funded by the DFG.

I moved to the University of Regensburg on 01.04.2024.
