Research and Teaching Topics
Tropospheric aerosol particles: sources and fates of air pollutants with a focus on Secondary Organic Aerosols (SOA) and Water-Soluble Organics, aerosol dynamics, regional air quality, health effects, and particle radiative properties.
Development of particle measurement systems: measurements of fine and coarse particle color, chemical composition and oxidizing potential. Instrumentation development for chemical speciation and measurement of color of water-soluble organics and the development of systems for measuring reactive oxygen species (ROS) of both gases and particles for health-effect studies.
