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 (2024-) and program committee member for QIP 2025.

Research Interests

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 coding bounds :)

I also enjoy noncommutative algebra, including tensor polynomial identities and matrix inequalities.
