RESEARCH INTERESTS (More information at SICRIS)   Research Fields  Use of ab initio (on the Hartree – Fock (HF) and the Density Functional (DFT) level of theory) and the semiempirical MO theory to examine the chemical systems in equilibrium as well as the chemical reactions with the emphasise on the intermolecular interactions (e.g. hydrogen bonds). Theoretical study of the reactions of polyoxides. Interaction and  binding of ligand molecules to biomolecules.
