Draft Report: You are what you breathe

Research Interests:
Atmospheric aerosols -- suspended particulates such as sea salt and smoke -- impact Earth's climate by absorbing and scattering solar radiation and altering cloud formation processes. The current level of scientific understanding of these aerosol processes is very low because of the diversity of aerosol composition and "chemical weathering" of aerosols during transport via reactions with trace pollutants, such as ozone. The atmospheric chemistry research group investigates the chemistry of trace pollutants with atmospheric aerosol surrogates containing adsorbed organic molecules prevalent in biomass combustion smoke. These lab models are used to characterize this chemistry under controlled conditions to quantify how aerosol properties change during exposure to pollutants.
