A student of the Physics Department of the St. Petersburg State University. My tutors were Prof. T.M.Zimkina and Dr. M.S.Nachmanson. BA degree was on the band structure calculations of the nitride borone crystal by the OPW method.

Postgraduate student of the Physics Department of the St.Peterburg State University (supervisors: Prof. I.V. Abarenkov and Prof. T.M. Zimkina.). During this time I investigated the electronic structure of light metal diborides. In this work the band structure of these crystals has been calculated with the OPW method. Using the wave functions obtained, the theoretical X-Ray spectra were also calculated. At the same time I was interested in the problem of the X-Ray exciton in alkali halides. In collaboration with I.V.Abarenkov a new method for intermediate radius localized states was developed in order to calculate the X-Ray excitonic states in KCL crystals.

During this time I gained experience in non-relativistic Hartree-Fock and relativistic Hartree-Fock-Dirac calculations of atoms in collaboration with Dr. V.F.Bratsev (St.Petersburg State University). I developed a computer codes for one-configuration and multi-configuration calculations of atoms. Relativistic effects were included. Our computer codes allow one to calculate not only optical and X-ray transition energies, but also chemical shifts of X-Ray lines, oscillator strengths, hyperfine constants etc. I studied nonrelativistic and relativistic atomic core potentials and pseudopotentials for ab initio electronic structure of molecules and clusters with heavy atoms.

Since 1991 I am working with Prof.R.A.Evarestov and Dr.V.Veryazov (St. Petersburg State University) on semi-empirical (CNDO and INDO) and ab initio (HF, DFT) band calculations of crystals (interband transition energies, densities of states, atomic charges, valencies, bond-orders etc.).

During the last few years my work was devoted to the calculation of electronic structure of molecules, clusters and solids. Besides the traditional approaches, such as MO-LCAO, we developed an original method using nonorthogonal localized orbitals in numerical forms. In particular these methods and computer codes allow one to perform non-relativistic and relativistic calculations of the electronic structure and various properties of atoms and two-atomic molecules. In collaboration with Dr. S. Kotochigova (NIST, USA) and Dr. V. Kuznetsov (St.Petersburg State University) the electronic structure of a series of diatomic molecules with heavy atoms were investigated including relativistic and correlation effects.

In collaboration with Prof. I.V.Abarenkov (St.Petersburg University) and Prof. V. Heine (Cambridge University), a combined MCSCF-LDA method was developed and tested on a simple prototype model.

In collaboration with Prof. I.V.Abarenkov, Prof. V.Heine (Cambridge University) and Dr. A.Shluger (University College London) a separable potential technique was examined and a new separable pseudopotential method was investigated. In particular, this potential helps to solve the embedding problem for solids with covalent bonding.

In collaboration with Prof. V.M.Shabaev (St.Petersburg State University) I calculated the higher-order electronic interaction and relaivistic corrections to the hyperfine splitting, to the g factor and to the transition probabiltis of high-Z ions, the isotopic shifts in highly charged ions, and Parity-Nonconserving effects in the heavy atoms.
