Chongai Kuang, an environmental scientist at Brookhaven, has won the 2012 Sheldon K. Friedlander Award from the American Association of Aerosol Research for his doctoral dissertation on the formation of aerosol particles in the atmosphere.
Cited as one of the most accomplished and talented aerosol scientists in the world, Kuang’s dissertation or thesis, focused on particle formation that occurs due to both natural and man-made emissions into the atmosphere that include contributions from sources such as organic bacteria and pollen as well as emissions released from the burning of fossil fuels. He studied how these particles are formed, developed models that predicted how they were formed, and also developed instrumentation to measure the particles as they formed. The award recognized his combination of elegant, theoretical descriptions of key processes with much needed observational constraints.
The field of aerosol science focuses not only on particle formation, but also on how these particles affect atmospheric conditions for clouds and the ripple effect that they can have on regional climates. Despite being commonly understood as the spray from an aerosol spray can, aerosols are any and all suspensions of solid and liquid particles in a gas, meaning everything from dust, sea salt, and allergens to car exhaust, cigarette smoke, and pesticides. The field also closely studies how this range of natural aerosols interact with those man-made ones, providing a detailed understanding of the effect aerosols can have on human health and global climate trends.
Within the Department of Energy, the models that scientists like Kuang develop are aimed at providing a better understanding of the environment for both scientists and policy-makers who are tasked with developing strategies to mitigate the effects aerosols have on the environment.
