Merlin Christ

I am a PhD student (since April 2020) in mathematics in the Quantum Universe Research School . My supervisor is Tobias Dyckerhoff
From September 12th to December 16th, I will be in Bonn at the trimester programm on Spectral Methods in Algebra, Geometry, and Topology.

Research interests:
Higher categorical structures in categorification and representation theory.
More specifically, I am currently studying perverse schobers (mostly on surfaces), which are certain sheaves/cosheaves of enhanced triangulated categories which categorify perverse sheaves. Applications are in the study of Fukaya-type categories and categories arising in the categorification of cluster algebras.

Publications and preprints:

• Cluster theory of topological Fukaya categories
  Preprint: arXiv:2209.06595
• Geometric models for the derived categories of Ginzburg algebras of n-angulated surfaces via local-to-global principles (video)
