B.Tech., Engineering Physics, Indian Inst. of Technology, Mumbai (1988).

PROFESSIONAL EXPERIENCE

Guest Scientist, Laboratoire de Physique Subatomique et de Cosmologie, Grenoble, France. June 2008 - August 2009

On research leave from my university, I just completed a 14-month visit to LPSC, Grenoble, as a guest scientist on a fellowship program sponsored by the French federal research agency CNRS/IN2P3 to collaborate with the ATLAS team at LPSC on studies of top quark production and decay at the LHC.

Presidential Research Professor (2011 - 2015)
Professor of Physics (2009 - present),Associate Professor of Physics (2007-2009), Assistant Professor of Physics (2007), Northern Illinois University. 2001 - present

Teaching: I have taught the following courses at the NIU Physics department:
Research: I am involved in the following collaborative projects:

Research Scientist (after May 1997), Post-doctoral Research Associate (till May 1997), State University of New York at Stony Brook. July 1995 - January 2001
As a reseach scientist, I contributed to the following tasks at DZero : During my post-doctoral appointment, I worked on the following projects:
Post-doctoral Research Associate, University of Iowa. September 1994 - June 1995
This one-year appointment was focused on studies of electron-proton collisions with the ZEUS detector at HERA (DESY).

Graduate Research Assistant, State University of New York at Stony Brook. August 1988 - September 1994
I conducted my thesis research under the direction of Prof. Roderich Engelmann. The dissertation was titled Searches for ppbar -> ttbar at sqrt(s) = 1.8 TeV using lepton+jets final states in the DZero detector. The analysis exploited distinctive topological characteristics of the signal, and led to the improvement of the lower limit for the mass of the top quark from 91 GeV to 131 GeV. The analysis techniques developed in the course of this research played a key role in the discovery of the top quark in March, 1995. I also contributed to the calorimeter reconstruction software and electron identification, wrote the online monitoring software for the central drift chamber (CDC) and had the primary responsibility for certifying its data quality.
