Since November 2024, I am Assistant Professor at the Institute of Theoretical Physics and Astrophysics of the University of Gdańsk. From January 2024 to October 2024 I was Junior Professor (CPJ) for Quantum Algorithms at the Bordeaux Computer Science Laboratory, where I also headed the Quantum information and Computation Group. From 2021 to 2023 I led the Quantum Error Correction Group at the Jagiellonian University in Kraków.
I was a postdoctoral fellow in the groups of Antonio Acín at ICFO Barcelona and David Gross at the University of Cologne (2018-2020). I was PhD student at the University of Siegen (2014-2017), advised by Otfried Gühne. My thesis won the 2019 Dissertation Prize by the section AMOP of the German Physical Society.
I’m an Editor at Quantum and program committee member for QIP 2025.

I work on the characterization of quantum correlations like entanglement and nonlocality, on quantum error correction (theory & experimental proposals), and on mathematical optimization in quantum information and computation. I also do a bit of mathematics in the field of on non-commutative algebra.
I like problems such as quantum Max Cut, the quantum marginal problem, making connections to graph theory, the detection of entanglement, quantum zero-error communication, and mutually unbiased bases :)
I also enjoy noncommutative algebra, including tensor polynomial identities and matrix inequalities.
