Summary:

15 years of experience in using and developing methods of atomic-scale structure analysis for statically and dynamically compressed materials using crystallographic and spectroscopic methods.

Main research direcation is on development of synchrotron radiation-based high-pressure x-ray diffraction techniques for quantitative structure analysis, including the development of ultrahigh spatial resolution structure analysis tools for shocked samples and pre-shot structure and microstructure e.g., defects, characterization, inclusions, conformational disorder.
