Research Interests

Yuri's research is focused on development of the Internet atomic databases, high-precision atomic structure calculations, modeling of plasma population kinetics and other aspects of plasma spectroscopy. This work includes multiconfiguration Hartree-Fock and Dirac-Fock calculations of atomic properties (energies, oscillator strengths, etc.), development of methods for disseminating scientific data over the World Wide Web, collisional-radiative modeling of non-Maxwellian transient plasmas, quantum-mechanical calculation of electron-impact broadening in multiply-charged ions.
