  Research Profile

My recent works were devoted to the new methods of construction of exact solutions of physically important equations: the Navier - Stokes equations for viscous fluid dynamics, Euler's equations of ideal fluid and gas mechanics and magnetohydrodynamics (MHD) equations. I have discovered an infinite family of new invariants of the axisymmetric Euler's equations and viscous MHD equations and have studied different regimes of dynamics of viscous and ideal fluids. I have developed methods of construction of moduli spaces of vortex and magnetic knots.

I am interested in recruiting graduate students who have some knowledge of fluid and gas mechanics and a good knowledge of computer graphics and numerical methods for solving finite-dimensional dynamical systems.
