What We Do

 The overarching goal of our research is to develop models from a fundamental perspective, that enable better predictions of the spatial and temporal distributions of ambient SOA, which are critical for mitigating the adverse impacts of PM_2.5 on climate and health. Our research projects uniquely span the measurement-model interface, and primarily involve: 1) comprehensive gas chromatography for identification of gaseous organic compounds that serve as precursors for SOA; 2) mechanistically-based models to explain and interpret laboratory and field observations of SOA, including new particle formation; and 3) development of parameterizations based on mechanistic models and observations. Current research projects involve developing models describing the growth of newly formed particles through acid-base chemistry, and developing parameterizations of SOA formation from anthropogenic, biogenic, and wildland fire emissions.
