born in 1988, in 2010 graduated from the Faculty of Physics and Mathematics of I. Yakovlev Chuvash State Pedagogical University. In 2013 he defended his thesis for the degree of Candidate of Sciences in Physics and Mathematics.

Since 2014 he has been working at the Institute of Earthquake Prediction Theory and Mathematical Geophysics of the Russian Academy of Sciences (IEPT RAS) as a senior researcher.

Teaching activity: from 2012 to 2014 he worked as a lecturer at the Department of Informatics and Computer Science of I. Yakovlev Chuvash State Pedagogical University.

His research interests are related to the biharmonic problem of the theory of elasticity. Within the framework of the biharmonic problem, he and his colleagues constructed examples of exact solutions to classical unsolved boundary value problems of the theory of elasticity with a long history in a half-strip and rectangle (basic, mixed, inhomogeneous, temperature problems). The most important result of the solution to the biharmonic problem was the theory of residual stresses (one of the key problems of the mechanics of deformable solids), which is of applied importance, in particular, for the mechanics of rocks.

He is the author and co-author of more than 30 scientific papers in leading Russian and international peer-reviewed scientific journals.
