Description and lab research areas:
Aerosols participate in many environmental processes affecting the climate, human health and ecosystems. The qualified candidate will work on topics related to organic aerosol aging, physical properties, and potential health effects. Our research efforts focus on: a) understanding the origin, molecular composition, atmospheric transformations, and optical properties of light-absorbing organic aerosols (anthropogenic, biogenic, urban, and biomass burning SOA), and b) connecting aerosol composition, its changes, and the resulting health effects.
