Research Interests:

  1. Regional Air quality studies in changing climate and it’s impacts on troposphere: Monitoring of tropospheric trace gases, in-situ observations and regional climate.
  2. Understanding the bio-geo chemical changes which are due to complex hydrological processes within the river basin under the scenarios of climate change, land use land cover change and water, agricultural and industrial practices or any other perturbation
  3. Experimental studies relevant to Atmospheric chemistry to measure very low (ppt/ppb) and the absorption coefficient of an atmospheric constituent such as the Cavity Ring Down Spectroscopy (CRDS) and Laser Induced Fluorescence (LIF) and also the combustion processes such as the shock tube method.
