The research is focused on theoretical and computational study of the dynamics of complex fluids and its applications to other areas such as mechanical and chemical engineering, materials science and geophysics. Mathematical aspects of research include the theory of asymptotic scaling and reduction of underlying differential equations, the theory of stability and bifurcations, perturbation and asymptotic methods, and numerical methods for partial differential equations.
