Research Interest

My research is on Computational Chemistry and spans many areas of Chemistry. These include Organic Chemistry, Photo Chemistry, Atmospheric and Interstellar Chemistry, Biochemistry, Dyes and Pigments, Catalysis, Nonlinear Optics and Molecular Electronics, etc. As in these days the interaction between theory and experiment is becoming more and more intimate, my current research focuses on giving theoretical explanation to experimental findings

Research Grants

Incentive Funding (R 40000.00 every year) from 2010 -2015.
Funding of 300000.00 for rated researcher from 2011-2012.
