Assistant Professor Education Education: PhD University of California, San Diego MS University of California, San Diego BS University of California, Berkeley Research Research Areas: Environmental/Atmospheric Chemistry Analytical Chemistry Research Interests: The goal of our work is to understand how the chemical composition of aerosol particles influences their properties in the atmosphere and their effects on clouds and air quality. Our work focuses on characterizing the chemical composition and properties of surface-active organics (surfactants) in atmospheric aerosol particles. We look at the effect of natural and laboratory surfactants in seawater on marine aerosol particle production, the composition and concentration of surfactants in atmospheric marine aerosol particles, and the influence of surfactants on cloud droplet properties. We work both in the laboratory building instruments and analyzing samples and in the field measuring and collecting ambient aerosol.
