Job description

The Astromaterials Research and Exploration Science (ARES) Division at NASA Johnson Space Center (JSC) and the Universities Space Research Association’s Lunar and Planetary Institute (LPI), both in Houston, Texas, are pleased to announce a term posting for a Postdoctoral Fellowship.

The Fellowship recognizes and promotes excellence in research for scientists within five years of their doctorate and is intended to encourage the development of young scientists in the field of astromaterials research that involves the study of the origins, isotopic and elemental compositions, structure, and evolution of presolar grains identified in meteorites, interplanetary dust, asteroids, and comets. Fellows are expected to be self-motivated and to define their own research direction and foci. The Fellow will be in residence at JSC while also being an employee of USRA and active at the LPI, and will be expected to interact with scientists of both organizations (see and Fellows will enjoy access to all of JSC’s laboratories and analytical instruments on the same basis as scientific staff.

The Fellow will perform NanoSIMS analyses of presolar grains and will be encouraged to coordinate these analyses with focused ion beam (FIB)-assisted transmission electron microscope (TEM) mineral characterization. The isotopic properties of presolar grains provides remarkable insight into astrophysical processes while their mineralogies allow us to understand dust condensation in stellar atmospheres and subsequent alteration in various environments. As these grains constitute a building block of the Solar System, understanding their origins and histories is intimately linked with understanding the origin of the Solar System.

The duties of this position at JSC include: performing scientific research in the presolar grains, presenting the results of this work as publications in refereed journals and presentations at conferences, participating in the academic community for this field, and contributing to the dissemination of planetary science information in the academic community and to the general public.

How to apply

Applicants for this position should have a Ph.D. in a planetary and space sciences-related field and a strong publication record. Fellows will be provided highly competitive levels of salary, research support, and travel support for two years, with possible extension for another year. Interested applicants should apply to the posting at USRA Careers and must submit a Curriculum Vita with list of publications and three professional references, and a two- to three-page statement of research interests. Questions can be addressed to Dr. Lisa Gaddis (
