Research interest

My research is at the intersection of analysis, algebra and combinatorics. Amongst others, I am primarily dealing with methods from functional analysis, links to free probability theory and symmetry structures of geometries within any framework, in particular a noncommutative one. I am mainly dealing with noncommutative algebras arising in the context of operators on Hilbert spaces, matrices in linear algebra or observables in quantum physics. My central objects are compact quantum groups and I am investigating them from different perspectives, using various methods interfering with many other areas of mathematics such as:
  • Functional analysis: (universal) C*-algebras, von Neumann algebras, K-Theory
  • Combinatorics: partitions of sets, finite graphs, counting problems
  • Algebra: Hopf algebras, automorphisms of graphs, computer algebra
  • Topology, cohomology: noncommutative topology (C*-algebras), K-Theory, (Hochschild) cohomology
  • Quantum symmetries: "easy" quantum groups, noncommutative harmonic analysis, quantum automorphisms of graphs
  • Geometry: noncommutative geometry, notions of symmetry, deformation/quantization
  • Tensor categories: representation theory of quantum groups, Schur-Weyl results
  • Mathematical physics: quantum mechanics (by von Neumann), notions of symmetry
  • Stochastical methods: distributional symmetries, free probability, Levy processes

Member (PI) of the SFB-TRR 195

Since 1 January 2017, I am one of the PI's of the SFB-TRR 195 Symbolic Tools in Mathematics and their Applications (RWTH Aachen, TU Kaiserslautern, Saarland University, and others), funded by the DFG (German Research Foundation). My project is: I.13 - Computational classification of orthogonal quantum groups.

Editor of Analysis Mathematica

Since January 2019, I am an editor of Analysis Mathematica for the area functional analysis, operator algebras and quantum groups. Submissions welcome!
