I am mainly interested in constructing and analyzing interacting theories of higher-spin gauge fields as well as in other closely related problems of classical and quantum field theories. In particular, together with colleagues we were first to derive quartic vertices in higher spin theories from AdS/CFT correspondence and studied their locality, constructed chiral higher-spin theories employing the light-cone gauge approach and established the relation of the latter theories to self-dual Yang Mills theory and sigma models, as well as computed simplest quantum corrections in higher-spin theories.
