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.
Current Research Projects
1. Emory/Georgia Tech Collaboration: Multi-Scale Assessment of Health Effects of Air Pollution Mixtures Using Novel Measurements and Models (SCAPE, for more details goto http://scape.gatech.edu)/
2. Investigating Secondary Organic Aerosol Formation (SOA) in the South Eastern US through simultaneous measurements of gas and particle concentrations, involving a novel PILS-AMS-CCN and a host of other instrumentationf ( SOAS, for more information goto soas2013.rutgers.edu) - NSF.
3. Measurements light absorbing carbon (i.e., brown carbon) in the free troposphere (DC-3 and SEAC4RS missions, see espo.nasa.gov/missions/seac4rs/content/seac4rs_home_page) - NASA .
