Planetary Scientist | NASA
Ann Nguyen is a planetary scientist and manager of the NASA JSC NanoSIMS 50L ion probe laboratory within the Astromaterials Research and Exploration Science Division at the Johnson Space Center. Her research focuses on the coordinated isotopic, chemical and mineralogical characterization of presolar grains in primitive meteorites and interplanetary dust particles (IDPs). These studies constrain models of stellar evolution, nucleosynthesis, and circumstellar grain formation, while also providing information on secondary alteration processes in the interstellar medium and the solar system. Additional research includes isotopic studies of early solar system condensates and organic matter in meteorites, IDPs, and comet Wild 2 samples returned by NASA’s Stardust mission.
Dr. Nguyen is a participating scientist on JAXA’s Hayabusa2 asteroid sample return mission. She is also a co-investigator on NASA’s OSIRIS-REx asteroid sample return mission and on the NASA New Frontiers CAESAR (Comet Astrobiology Exploration Sample Return) mission.
