Research Interests:

River basin studies; Hydrological Modelling and Understanding of Biogeochemical changes associated with of climate change, land use land cover change and water, agricultural and industrial practices or any other Natural or Anthropogenic perturbation.
Atmospheric Chemistry; Experimental studies relevant to Atmospheric chemistry to measure very low (ppt/ppb) and the absorption coefficient of an atmospheric constituent and also the computational kinetics of ultra-fast atmospheric reactions by using DFT/ab-intio methods with Gaussian (basis set) - theory
