研究领域

Physical and Atmospheric Chemistry. Aerosol optical properties are of specific interest. Current Research Interests Aerosols are ubiquitous in the atmosphere and play intriguing roles in physical and chemical processes impacting fields such as atmospheric sciences, climate change, combustion, medicine, and health. Aerosols are fine, solid or liquid particles suspended in a gaseous medium. They are composed of many molecules since the bulk of aerosols are 10s to 100s of nanometers in diameter and can have complicated chemical compositions. We investigate aerosol properties using physical chemistry, specifically spectroscopic methods and relate the results to broader questions, especially regarding climate change. Complex aerosols are of special interest. Whether uniquely shaped or of mixed composition, we are interested in understanding their optical and morphological properties and how these change as a function of environmental influence.
