Olga’s major research expertise is within multidisciplinary field of the high-pressure research focusing on studies of structural, vibrational, and thermodynamic properties of materials under extreme conditions of high pressure and high temperature. High-pressure is a very powerful tool for understanding of physical properties and stability of the matter as well as an instrument for synthesis of novel materials or materials with tailored properties.

Olga carried out research into structural and thermodynamic stability within Fe-O system at extreme high-pressures and high-temperatures and studied transition metal and main group element nitrides under extreme HP. She built a double-sided laser-heating system for heating samples inside the diamond anvil cell and developed combined High-Pressure XRD/XANES method at HPCAT beamline (APS) to look into a synthesis and characterisation of novel transition metal-alkali metal alloys.

Olga’s current research interests are focused currently at establishing a new Extreme High Pressure SAXS (EHP-SAXS) technique and research for I22. Rapidly growing demand in EHP-SAXS is due to numerous applications in both solid state and soft condensed matter. To name a few, a high-pressure capability to control nanostructured metal architectures is important in catalytic, sensor, and fuel cell technologies; high-pressure engineering of nanoparticle assemblies is proved to be very useful in development of artificial solids, as metamaterials, with potential applications in nanoelectronic and optical devices. Olga aims at investigating the effect of high-pressure and deviatoric stress on formation of higher-dimensional nanostructured architectures from nanoparticle arrays.
