I am currently working as an Associate Professor at the Theoretical Statistics and Mathematics Division of the Indian Statistical Institute (ISI). I primarily stay in the Theoretical Statistics and Mathematics Unit at the New Delhi Centre of the institute, but I also spent time at the Theoretical Statistics and Mathematics Unit at the Headquarters of ISI in Kolkata.

At the moment, I am in the Theoretical Statistics and Mathematics Unit at the Headquarters of ISI in Kolkata. My office in ISI, Kolkata is at Room Number 3.15 on the 3rd floor of the A. N. Kolmogorov Bhavan. My office number is +91 (0)33 2575 3425.

Earlier, in the Fall 2008 semester (August 1 - December 4, 2008) I was in ISI, Kolkata, then again I was there in the Summer 2011 (May 1, 2011 - July 30, 2011).

In the academic year 2013 - 2014 (September 2013 - May 2014) I visited the Department of Statistics of the University of California, Berkeley as a visiting Associate Professor. In UC, Berkeley my office was at Room # 387 on the 3rd floor of the Evans Hall.

I graduated from University of California, Berkeley with Ph.D. in Statistics in May 2003. My dissertation was on Max-type Recursive Distributional Equations and I worked under the guidance of Professor David J. Aldous. To see a summary of my dissertation click here.

Before joining ISI, I did a two years postdoctoral study (September 2004 - August 2006) at the Chalmers University of Technology, Gothenburg, Sweden, in the Department of Mathematics and Mathematical Statistics, where I worked under Professors Jeffrey Steif, Olle Häaggströom and Johan Jonasson. Earlier (September 2003 - August 2004), I was at the Institute for Mathematics and Its Applications, University of Minnesota, Minneapolis, as a postdoctoral member, and worked with Professor Ofer Zeitouni.


Seminars:

I organized the weekly seminar series of the Theoretical Statistics and Mathematics Unit, ISI, New Delhi for four years, from Fall 2006 till Fall 2010 (except in the Fall 2008 when I was not in Delhi it was organized by Maneesh Thakur). From Spring Semester 2010 till Fall 2010 my co-organizer was Deepayan Sarkar.

Research:

Summary of Research Interest: 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.
