Research interests

Literally almost any topic related to high energy physics can catch my attention. However, for a living, I am mostly working on certain aspects of quantum field theory and its phenomenological implications. Here is an example of questions that I am currently pondering on.

Nonperturbative phenomena

What is the distinctive role of nonperturbative effects, such as instantons, in quantum theories? How are they related to perturbation theory?

Light dark matter

How can we search for very light dark matter? From a field theory perspective, are there self-consistency conditions that any light dark matter candidate has to fulfill?

Axions and condensed matter

Which traces would axion-like particles leave in magnetic materials featuring skyrmions? How do topological terms change their behaviour?
