Professor Ruzhansky''s research includes partial differential equations of hyperbolic type, Schrödinger equations, more general dispersive and evolution equations, as well as elliptic and hyperbolic systems of equations. His main interest is in various (local and global) properties of solutions to these equations, their geometric analysis, and further applications of these properties to semilinear and nonlinear equations.

Examples of the properties include microlocal analysis, properties of Fourier integral operators, estimates in Lp, Sobolev and other function spaces, singularities of the Hamiltonian flows, time asymptotics, dispersive, smoothing, and Strichartz estimates, etc.

He is also interested in the theory of pseudo-differential operators on spaces with symmetries, such as Lie groups, symmetric, and homogeneous spaces, as well as more general manifolds.
