About the NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
Description:
The isotopic compositions of minerals, organics, liquids, and gaseous species from an array of planetary bodies throughout the Solar System have enabled critical insights into the provenances of as well as the physical and chemical processes that have modified those materials. Our group combines laboratory experiments, analytical measurements, mathematical modeling, and computational chemistry to investigate such processes and the isotopic signatures that they impart on simple organic and inorganic molecules in both terrestrial and extraterrestrial rocks and minerals. Postdoctoral fellows would contribute to this work in two ways: 1) performing laboratory experiments to determine isotopic fractionations in relevant planetary environments (e.g., carbon or hydrogen isotopic fractionation in simple hydrocarbons between Titan’s lakes and its atmosphere, adsorption-driven fractionation of hydrogen and oxygen isotopes between adsorbed water and the martian atmosphere) and/or 2) performing high-fidelity quantum- and statistical-mechanical as well as molecular dynamics simulations of the same (and other) fractionations to elucidate the underlying chemical physics drivers of such processes.
These and other, comparable projects are highly cross-disciplinary in nature and at the cutting edge of isotope geochemistry. The incorporation of techniques from computational chemistry in particular is essentially a new way of approaching questions in planetary science and isotope geochemistry. The most recent Planetary Science & Astrobiology Decadal Survey emphasizes the role of laboratory returned-sample analyses—particularly isotopic data—as a major focus for future NASA research and missions. Current work in our group supports several active missions, including MSL (Curiosity) and OSIRIS-REx, as well as missions in development (Mars Sample Return) and those still in the concept phase.
