Aerosol science and air quality engineering

Aerosol science and air quality engineering is concerned with fine particles which, when present in the atmosphere, are known lung irritants, contribute to visibility degradation, and affect light scattering and absorption, making them an important to the atmospheric energy balance and climate change. Little is known, however, regarding the influence of particle shape, surface composition, and even size distribution to these problems. Work in our laboratory utilizes kinetic and thermodynamic models and fundamental studies under controlled conditions to better understand the influence of these particles, and to devise strategies to control them. Specific current projects include studies of Hg pollutant chemistry and of fine particle reactivity.
