RESEARCH<br />
RESEARCH INTERESTS<br />
My research focuses on investigating source-receptor relationships for airborne pollutants. I am<br />
specifically interested in understanding <strong>the</strong> chemical composition and optical properties <strong>of</strong><br />
ambient particles. I also focus on studying <strong>the</strong> atmospheric transformations <strong>of</strong> aerosol and assess<br />
<strong>the</strong>ir relationships with gaseous co-pollutants, and understand how specific aerosol sources affect<br />
climate. The overall goals <strong>of</strong> my work are to provide scientific inputs for policy making, and<br />
develop strategies/control technologies to protect human, animal, and plant health.<br />
While it is well recognized that changes in greenhouse gas concentrations<br />
influence climate <strong>the</strong>re remains considerable uncertainty in our understanding <strong>of</strong> <strong>the</strong> role <strong>of</strong><br />
aerosols and <strong>the</strong>ir interplay with gaseous co-pollutants in regulating and altering climate, both on<br />
regional and global scales. In an effort to overcome this gap in understanding a lot <strong>of</strong> recent<br />
scientific studies have focused on <strong>the</strong> climate forcing effects <strong>of</strong> aerosols in general, and black<br />
carbon in particular. Research efforts have also highlighted <strong>the</strong> conflicting role <strong>of</strong> black carbon<br />
(warming) and sulfate (cooling) aerosols in radiative forcing. Additionally, recent studies have<br />
shown that ambient aerosols influence climate not only via direct radiative forcing and indirect<br />
aerosol-cloud interactions, but also through biogeochemical feedbacks on longer time-scales. My<br />
research activities are an endeavor to contribute as many “pieces” as possible to help solve <strong>the</strong><br />
“aerosol induced climate change puzzle”.<br />
