My main research interest is in theoretical and applied probability mainly focusing on discrete problems arising out of combinatorics, statistical physics and computer science. In particular I am interested in random graphs, probability on tress, combinatorial optimization and statistical physics problems, recursive distributional equations, branching random walks, percolation theory, interacting particle systems, Markov chains and their mixing behavior, random walks in random environment and urn models. I also keep strong interest in theoretical statistics and probability questions arising out of it.
