Research Interests
My primary research interests and experience are in the areas of water flow,
and fate and transport of chemicals through porous and fractured media. Recently I have developed research interests in water management in regions affected by the South Asian tsunami. I have
conducted experimental, field and numerical modeling work related to this research.
A partial list of my past and current funded research projects is given here
to show my diversity of interests and multi-disciplinary nature of problems
