I am currently a postdoctoral research in ERC Synergy grant POCOCOP, hosted by Libor Barto at the Department of Algebra, a part of the Faculty of Mathematics and Physics, Charles University.

Previously (February 2023--May 2024), I was a postdoctoral researcher at LIMOS laboratory at the University of Clermont Auvergne, hosted by Florent Foucaud.

Even before that I was a PhD student and a part-time researcher at Computer Science Institute, a part of the Faculty of Mathematics and Physics, Charles University. My advisor was Jaroslav Nešetřil (see my genealogy).

Research interests

• Constraint satisfaction problems
• Graph homomorphisms and algebraic graph theory in general
• Algorithms and complexity
• Cooperative game theory
