PROFESSIONAL INTERESTS

My current research interests are concerned with the development of new methods for the analysis of x-ray absorption spectra using Molecular Dynamics simulations, Quantum Chemistry calculations, Reverse Monte Carlo technique, and Machine-Learning methods.

I am the author of the original x-ray absorption fine structure (XAFS) data analysis software package "EDA" and the original approximated method for performing the MS calculations of XAFS. In 2002 I have designed and constructed a high-performance computing cluster LASC, at the Institute of Solid State Physics, University of Latvia, whish was rated at the 184 place in ClustersTop500 in May 2003. The LASC cluster is currently used for parallel quantum chemical calculations and simulations of x-ray absorption spectra of nanoparticles, molecules and crystals.

My scientific interests in the fields of physics and materials science are concerned with oxide compounds containing transition metal and rare-earth ions (crystals, nanomaterials, amorphous and crystalline thin films, glasses, solutions). Currently, I participate in the national and international research projects on multifunctional materials for smart windows, solar cells, transparent conducting coatings, sensors, phosphours and photocatalysts. The complex investigations of physical and chemical properties of above mentioned materials require the use of different experimental and theoretical techniques. In particular, I have expertise in conducting studies using synchrotron x-ray absorption spectroscopy (XAS), confocal spectromicroscopy (Raman and luminescence), atomic force microscopy, optical absorption/luminescence spectroscopy and x-ray diffraction.
