Personal profile
Research
My research is focused on various theoretical and phenomenological aspects of the Standard Model and beyond, as well as their cosmological implications in a broad sense.
Teaching
Currently, I teach three courses at the Department of Astronomy and Theoretical Physics: Classical Mechanics (FYTN09), Cosmology and Astroparticle Physucs (FYTN11) and Introduction to Quantum Field Theory (FYTN10). Besides, I supervise bachelor, master and doctoral students.
Professional work
I am a Master programme coordinator in theoretical particle physics and an organiser of science coffee seminars (joint between theoretical and experimental particle physics groups) at our department.
