Our research is focused on the development and applications of methods for accurate computational studies of electronic structure, geometry, vibrational spectra, reaction mechanisms, and one-electron properties of organometallic molecules, molecular ions, and molecular clusters in their ground and excited electronic states. We are interested in both small and large molecules. For small systems we use all-electron techniques; for larger molecular systems we employ pseudopotential methods. In our work we study systems of very different sizes, from atoms to proteins.

We are specifically interested in:

• Development, calibration, and applications of pseudopotential methods required to deal with large molecules or molecular systems containing heavy atoms; our model core potentials allow for the description of the scalar relativistic effects.
• Development and applications of methods to calculate both 1- and 2-electron spin-orbit effects.
• Development of basis sets for all-electron relativistic calculations on molecules containing very heavy, trans-uranium atoms.
• Studies of molecular structure and properties of very large molecules and molecular clusters using both non-relativistic and scalar-relativistic model core potential representation of the core electrons and correlated wavefunctions or density functionals for the description of the valence electrons. We are particularly interested in the interactions of such systems with metal ions.
• Studies of weakly bonded systems containing rare-gas atoms in ground and excited electronic states.
• Studies of novel compounds that contain atoms of rare-gas elements from argon to radon.
• Modeling of novel anti-cancer drugs. In this case, in order to be able to represent both the drug molecule as well as the target protein, we use the hybrid QM/MM approach, with the quantum mechanical treatment used for the drug molecule, and molecular mechanics used to model protein.
