Research Teaching Curriculum Vitae

I graduated from University of California, Berkeley with PhD 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.

I am currently working as an assistant professor at the Theoretical Statistics and Mathematics Division of the Indian Statistical Institute (ISI). I will primarily stay at the Theoretical Statistics and Mathematics Unit at the New Delhi Centre of the institute, but from time to time I will also work as a joint faculty at the Theoretical Statistics and Mathematics Unit at the Calcutta Center of ISI.

In Fall 2008 semester (August 1 - December 4, 2008) I was in ISI, Kolkata. I'll again be in ISI, Kolkata from May 1, 2011 till July 30, 2011. In ISI, Kolkata my office is in Room Number 3.16 at the 3^rd floor of A. N. Kolmogorov Bhavan. There my office phone number is +91 (0)33 2575 2312.

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 Professor Maneesh Thakur). From Spring Semester 2010 till Fall 2010 my co-organizer was Professor Deepayan Sarkar who is currently the organizer of the seminar.

Conferences:

• I am co-organizing with two of my colleagues, Siva Athreya from ISI, Bangalore and Krishanu Maulik from ISI, Calcutta the Lectures on Probability and Stochastic Processes (LPS): An annually held workshop in India on current active research topics in probability and stochastic processes.
• I am co-organizing with my colleague, Deepayan Sarkar from ISI, Delhi the Workshop on Airspace Safety Monitoring: An workshop jointly organized with Airports Authority of India (AAI). To be held in ISI, Delhi during May 7 - 11, 2012.

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, urn models. I also keep strong interest in theoretical statistics and probability questions arising out of it.
