Prof. Dmitry V. Lychagin is a Professor and Doctor of Physical and Mathematical Sciences, heading the Department of Mineralogy and Geochemistry at the National Research Tomsk State University. He also serves as a leading researcher at the Center for Collective Use "Analytical Center for Geochemistry of Natural Systems." Prof. Dmitry V. Lychagin is a leading specialist in the structural and crystallographic analysis of solids. His research encompasses both experimental and numerical modeling of minerals, metals, and alloys. A key focus of his work is investigating deformation behavior, surface morphology, and crystal defects in single crystals and polycrystals to analyze the patterns and mechanisms of deformation under static loading, fatigue, and friction. His expertise includes advanced analytical techniques such as transmission and scanning electron microscopy, crystallographic analysis, and mechanical testing. Prof. Lychagin actively contributes to the academic community as a member of several dissertation councils and the TSU Expert Council.
