Gregor Schaumann

Gregor Schaumann is a researcher at the Chair of Mathematics X (Mathematical Physics) within the Institute of Mathematics at the University of Würzburg, Germany. He specializes in the interplay between algebra and topology, particularly focusing on quantum algebra, low-dimensional topology, and higher category theory.

Research Interests:

• Topological field theories (TFTs) and associated manifold invariants
• Tensor categories and their representations
• Module categories and bimodule structures
• Higher categorical frameworks for mathematical physics
• Fusion categories and categorical quantum groups
• Orbifold constructions in TQFTs

Scientific Contributions: His recent work includes foundational studies on Grothendieck-Verdier categories, fusion quivers, and generalized orbifolds in Reshetikhin-Turaev TQFTs. He has also advanced the understanding of Eilenberg-Watts calculus and pivotal tricategories.

Teaching & Advising: Gregor supervises bachelor's and master's theses and teaches courses such as Linear Algebra for GMR teaching candidates, Introduction to Knot Theory, and seminars in algebraic topology and geometric mechanics.

Collaborations: He collaborates with international researchers including Jürgen Fuchs, Ingo Runkel, Christoph Schweigert, and Nils Carqueville, with whom he co-organizes the Higher Structures & Field Theory Seminar.
