This research opportunity is focused on the study of elementary reactions and photochemical processes important in Earth and planetary atmospheres. For Earth's atmosphere, we focus on radical-radical reactions that control ozone destruction in the stratosphere, including the chemistry of the polar "ozone hole". Our work also includes the study of mechanisms for the formation of urban smog and the degradation of tropospheric air quality by pollutants and biogenic hydrocarbons. The kinetics and photochemistry of the atmospheres of Mars and Titan are studied to enable comparisons between computer models and composition measurements from spacecraft and ground-based instruments. We use state-of-the-art techniques for the study of reaction mechanisms and photochemical processes including laser photolysis and discharge-flow, combined with detection by laser-induced fluorescence, cavity ringdown and frequency modulation spectroscopy and mass spectroscopy.
