Academic Background

I obtained my Ph.D in Operations Research from Cornell University under the supervision of Prof. Rick Durrett .

I did my Bachelors (B.Stat.) and Masters (M.Stat.) in Statistics with specialization in Mathematical Statistics and Probability from Indian Statistical Institute, Kolkata. I received M.S. in Operations Research and Information Engineering from the Department of OR & IE of Cornell University. My thesis advisor is Rick Durrett.

Research Interests

My primary research area is probability theory and its applications. My research interests include random networks, stochastic spatial models, first-passage percolation, percolation, as well as processes that arise in applications to physics and biology.
