Linking emissions to climate via chemistry
I am interested in the connections between natural emissions of gases and particles to the atmosphere and the global climate system. Currently my research focuses on the chemistry responsible for forming new particles from gas phase precursors. This process is referred to as new particle formation and it contributes to the formation of clouds by providing nuclei onto which water can condense to form cloud droplets. Clouds play a major role in the regulation of earth’s climate by reflecting and absorbing radiation, and accurate predictions of future climate depend on a comprehensive understanding of cloud formation.
My main projects recently are focused on understanding the origins of marine aerosol in the Atlantic and Arctic, and on the health impacts of hookah (water pipe) smoke.
