"Our group is dedicated to experimental investigations of charge carrier and spin dynamics in semiconductors and nanostructures. For this purpose, we use modern methods of ultrafast and nonlinear optics. These include excitation-interrogation spectroscopy with a time resolution of up to 50 femtoseconds, time-resolved Kerr microscopy, and second and third optical harmonic analysis.

At the moment, the main issues studied are spin dynamics and spin transport in two-dimensional electron gases under the influence of spin-orbit coupling, two-photon transitions in semiconductors, charge carrier dynamics in VO2 and GaN/AlN heterostructures, plasmonic functionalizations of heterostructures, optical properties of modern monolayer semiconductors such as MoSe2."
