My broad research interest is to investigate the role of aerosols in climate change mechanism through radiative transfer processes. This involves estimation of direct and indirect radiative forcing of aerosols over various 'hot spot' regions around the globe in terms of contribution from major aerosol species such as black carbons, organics, sulfates etc. The tool that I am currently using is climate modeling. I extensively use remote sensing data from satellites as well as in-situ data from measurements across the world to validate the model results. During my graduate studies, I also carried out laboratory measurements of aerosols and participated in many field campaigns.
