I am a postdoc at the Department of Algebra, Faculty of Mathematics and Physics, Charles University, Prague, Czech republic. I am working on the ERC Synergy project POCOCOP, supervised by Libor Barto.
Apr 2023 – Mar 2025: I was a postdoc at the Technical University of Denmark. I was working on a project, led by David Roberson, which relates quantum information theory and graph homomorphisms.
Apr 2022 – Mar 2023: I was a postdoc at the University of Neuchâtel, hosted by Alexander Kolpakov.
Oct 2016 – Feb 2022: I was a PhD student at the Department of Applied Mathematics, Faculty of Mathematics and Physics, Charles University.
research
- Symmetries of discrete objects, in particular the graph isomorphism problem, automorphism groups of graphs, Weisfeiler-Leman dimension.
- Mathematics of quantum information, in particular problems arising from the interactions of quantum information theory, quantum groups, operator algebras, and graph theory.
- Quantum groups, in particular quantum automorphism groups of finite graphs.
