Welcome to the

Our research is aimed at investigation of structural and electronic dynamics in condensed matter systems using ultrafast and non-linear optical spectroscopy techniques. Specifically, we investigate the coherence mechanisms in organic-inorganic hybrid perovskites, charge dynamics in atomically thin “2D” semiconductors, and quantum emitters in solid-state wide-gap semiconductors.
