Academic background

I obtained my Ph.D. in Statistics from University of California, Berkeley under the supervision of Sourav Chatterjee and Steve Evans.

I did my Bachelors (B.Stat.) and Masters (M.Stat.) with specialization in Mathematical Statistics and Probability from Indian Statistical Institute, Kolkata. My Master's theis was on Adaptive Design for Locating the Maxima of a Regression Function : A Nonparametric Approach under supervision of Probal Chaudhuri.


Stein's method, Concentration inequalities, Random Graphs, Random Matrices, Large deviations, Markov chains, Statistical Mechanics, Percolation.
