Introduction

I am a postdoc at RUB (Bochum, Germany), in the Quantum Information team of Michael Walter.

I obtained my PhD degree at IRIF, Université Paris Cité in September 2025, under the supervision of Frédéric Magniez. The title of my thesis was Quantum property testing and algebraic topology (pdf).

Before that, I obtained my bachelor’s and master’s degrees in computer engineering at the Budapest University of Technology and Economics.

Research topics: quantum query complexity, property testing, topological data analysis.
