Titan, Saturn's largest moon, possesses a thick nitrogen atmosphere and a surface dominated by organic molecules. Our group performs a wide array of experiments to study the chemical processes that control the evolution and composition of Titan's surface. Solubility, precipitation, photochemistry and low temperature thermal reactions are studied using infrared, Raman and ultraviolet spectroscopies, optical microscopy, synchrotron x-ray diffraction and neutron diffraction.

Current research focuses on the formation of organic co-crystals at low temperature, and the reactivity of carbon dioxide with amines to form carbamic acid. We are also developing ultraviolet and infrared fiber optic probes for the in situ chemical characterization of Titan's lakes.

Experience in spectroscopy, ultrahigh vacuum techniques, and/or experimental physical chemistry is desired.
