Research Interests Development of ab initio quantum chemical methods, in particular, multireference configuration interaction. Theoretical description of electronically excited states, molecular spectra and photochemistry, including coupling of electronic and nuclear motion (non-adiabatic effects), spin-orbit effects and non-radiative processes. Atmospheric molecules and ions, their lifetimes in excited states and decomposition due to radiative and non-radiative processes. Stability and building principles of small clusters.
