I am interested in exactly solvable systems in theoretical high energy physics and statistical physics: more specifically, in 1+1 dimensional integrable quantum field theories and spin chains. I am studying the interplay of perturbative and non-perturbative effects in quantum field theories via resurgence theory and finite volume/temperature effects for form factors, and also ergodicity breaking in quantum many-body systems.

I participated in teaching a tutorial course for quantum mechanics during the autumn semesters of the years 2019 - 2021 at ELTE.
