The Jet Propulsion Laboratory invites applications for a Scientist who will bring new expertise to and ensure continuity of existing capabilities at JPL in planetary science. The successful candidate will develop models for the chemical evolution of Europa, Enceladus, Titan, Ganymede, and other ocean worlds in support of the Icy Worlds, Titan, and Vital Signs teams. The candidate will investigate the detailed chemical evolution of Europa’s interior and its ice. Perform NASA funded research, including setting up and conducting novel experiments to measure chemical properties and processes applicable to planetary interiors. Investigate the metamorphic evolution of Ceres’s rocky mantle and support mission formulation as a subject matter expert on ocean world chemistry.


  • PhD in geochemistry, planetary geophysics, or a related field.
  • 3-4 years expertise in applying meteoritics, petrology, aqueous geochemistry to problems in astrobiology.

    The following qualifications are preferred:

  • Knowledge of geophysical forward modeling and inverse theory, high-pressure experimental design and implementation.
