INDIAN STATISTICAL INSTITUTE
(Delhi Centre)
I am currently working as a 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 some times at the
Theoretical Statistics and Mathematics Unit at the
Headquarters of ISI in Kolkata. I have been in Kolkata several times now,
Fall 2014 (June 09  December 20, 2014), Summer 2011 (May 01  July 30, 2011), Fall 2008 (August 01  December 04, 2008), Fall 2018 (July 01  December 23, 2018) and in Fall 2019 (November 01  30, 2020).
Majority of the times, my office in ISI, Kolkata is at Room Number 3.4 on
the 3^{rd} floor of the A. N. Kolmogorov Bhavan. When I am in my office in Kolkata,the office phone number is
+91 (0)33 2575 3425.
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 3^{rd} floor of the Evans Hall.
I graduated from University of
California, Berkeley with Ph.D. in Statistics in May 2003. My
dissertation was on
Maxtype Recursive Distributional Equations and I worked under the guidance of
Professor David J. Aldous. To see a summary of my dissertation

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.

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.
