Research Focus

My research interest includes study of Completely positive maps and semi-group of Completely positive maps (quantum dynamical semi-group) on C* and von Neumann algebras and understanding of quantum dynamical semi-groups by using the theory of Hudson-Parthasarathy quantum stochastic calculus. Recently we have some characterization result for non-commutative unitary processes with independent and stationary increments. In operator theory I am also interested in study of self-adjoint operators and their perturbations.
