Biography

Rahul Zaveri has a wide range of research experience in investigating the fate of anthropogenic and biogenic trace gas and aerosol emissions and their effects on air quality and climate change. His expertise is in modeling the complex physical and chemical processes occurring in the gas-, aerosol-, and cloud-phases and their climate-related properties. He is the scientific lead for the gas-phase photochemical mechanism CBM-Z and the comprehensive aerosol model MOSAIC, which have been implemented in the fully-coupled meteorology-chemistry model WRF-Chem. Dr. Zaveri has also participated in and led field campaigns to study the formation and evolution of oxidants and aerosols and their climate-related properties downwind of large urban areas.
