My work lies at the interface of mathematics and computer science. I study constraint satisfaction problems and their approximation and promise variants using universal algebra, homotopy theory, combinatorics, and logic.
Oct 2023 I am joining the University of Birmingham as an Assistant Professor!

I was an IST-Bridge Fellow at Institute of Science and Technology Austria with a project ‘Topology and the complexity of approximate graph colouring’ supported by MSCA (2022–2023). Before that I went through a few post positions at Oxford (2021–2022) and Durham University (2018–2021) in the UK, at TU Dresden (2016–2018) in Germany, and at Jagiellonian University (2016) in Poland. I had a chance to work on two ERC grants: Standa Živný’s Starting Grant ‘PowAlgDO’ and Manuel Bodirsky’s Consolidator Grant ‘CSP-Infinity’.
I received my PhD at Charles University in Prague on 29 Feb 2016. My advisor was Libor Barto.
