Research InterestMy main motivation in doing research in physics is to understanding the fundamental lawsof nature. One such law is the law governing the forces between the fundamental particlescalled quarks and gluons. Experiments show that protons and neutrons are made of quarksand gluons. Still in nature we never find free quarks or gluons, they always seem to beconfined inside particles like protons and neutrons. A promising way of understanding thisproperty is to assume that quarks are bound to each other by a string. Surprisingly the stringseems to live in four dimensions, even though the quarks live in familiar three dimensions.I am using this approach to understand the details of the forces between quarks. I am alsotrying to understand the emergence of this extra dimension.

Physics for Sustainable DevelopmentFrom 1994-2003 I worked with a voluntary organization, The Ajit Foundation. My mainfocus during this period was to use my skills as a physicist to develop tools that could helpa village manage its water resources in a sustainable and reliable manner. I converted thesetools into easy to use free software.

{ SimTanka: SimTanka is a software for designing rainwater harvesting systemswith covered tanks that are reliable against drought. Such rainwater harvestingare traditionally called Tanka in Rajasthan. The software is based on the techniqueof Monte-Carlo simulation, that allows the software to take into account probabledrought years.

{ Jal-Chitra: Jal-Chitra is a software I developed in a close collaboration withBarefoot College, Tilonia. This software is an attempt to help village panchyatdevelop a strategy for drought proofing a village. Jal-Chitra does this by gener-ating the water-budget for the village and by displaying information about waterresources available to village on an interactive map.

I was interviewed on 27 December 2011 by BBC Radio 4 about my work on Jal-Chitrahttp://www.bbc.co.uk/programmes/p00mlrk6
