I am currently a postdoc (‘University Assistant’) in Časlav Brukner's group at the University of Vienna and IQOQI Vienna.

My research lies at the interface between quantum foundations, mathematical physics, and philosophy. Using the new concepts of quantum information theory, I try to shed light on some of the foundational problems of quantum mechanics, in particular the quantum-to-classical transition, the preferred-basis problem and the measurement problem. I also have a long-term interest in studying the nature of space and time for quantum matter, in the quest of a quantum theory that does not rely on a pre-existing background spacetime.

More generally, my main motive is passion and exploration of the human mind. I seek to give fullness to the mathematics I use, to load them with meaning, be it physical or philosophical.

I have recently given a 5-hours lecture on the quantum-to-classical transition at CPT, Marseille, focusing on two main approaches: decoherence theory and the coarse-graining program. This gave me the opportunity, not only to present the topic in a quite personal way and emphasise some its usually neglected aspects, but also to assess what remains to be done to solve the question, as well as to include a variety of historical and philosophical remarks. More broadly, it allowed me to share my vision of physics. The course is part of a longer series Introduction to quantum foundations & quantum information started in November 2025.
