Research interests: nonlinear models of deformable solid mechanics and geomechanics, anisotropic damage, orientation effects, fracturing, true triaxial loading, X-ray computed tomography, acoustic emission, petroelastic modeling, fault zones, trigger effects, multifield modeling, anisotropy, Kaiser effect, slow deformation waves.Main results: 

● New models of deformation of fractured porous media under complex three-dimensional trajectories of quasi-static and cyclic deformation were developed to describe orientation/tensor effects of damage development and compaction.

● For the first time, the orientational character of the Kaiser effect in three-axis compression of rocks was theoretically described. ● The azimuthal dependence of poroelastic response to passage of teleseismic waves from distant earthquakes was described for the first time.

● New techniques have been developed to experimentally determine the micromechanisms of fracture in brittle materials, as well as to study spatiotemporal deformation localization patterns in quasi-plastic materials using optical and acoustic non-destructive testing methods.

●  For the first time, slow deformation waves were detected during the formation of shear zones in model materials. Patterns of their propagation and interaction with discontinuous structures of different ranks were established.Member of the Russian National Committee on Theoretical and Applied Mechanics.Member of the editorial board of "Izvestiya RAS.
