Research<\/h2>\n
\n\n

Poor air quality over the Indo Gangetic Plain has become a matter of public debate and concern. Our research group works on improving air quality action plans by conducting source apportionment studies, deploying low-cost air pollution sensors and developing emission inventories. We also seek to understand the impact of air pollution on food crops and natural vegetation with the help of leaf porometer measurements and stomatal conductance models. Sophisticated single particle techniques such as Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AF) and analysis of organic molecular tracers using CHARON TOF MS help us to understand the aerosol composition, study source signature and chemical transformations and understand the effect of particles on human health.<\/p>\n
