About this position
The California Institute of Technology is inviting applications for two postdoctoral fellowships in the Division of Geological and Planetary Sciences: the Melza M. and Frank Theodore Barr Postdoctoral Fellowship and the O.K. Earl Postdoctoral Fellowship. Both fellowships support innovative research in earth and planetary sciences, with strong encouragement for interdisciplinary projects.
The Barr Fellowship focuses particularly on work connected with the Caltech Center for Comparative Planetary Evolution, which combines astronomy, geology, and biology to investigate the origin and evolution of planetary systems and their biospheres. It lasts three years. The O.K. Earl Fellowship supports exceptional research in earth and planetary sciences, especially interdisciplinary work, and lasts two years.
Relevant research areas include geobiology, geochemistry, geology, geophysics, petrology, seismology, atmospheric science, oceanic science, and planetary science. Applicants with backgrounds in physics, chemistry, biology, computational science, or mathematical science are encouraged to apply. Candidates are typically within two years of receiving their Ph.D., and the fellowship requires completion of the Ph.D.
Each fellowship provides an annual stipend of $80,000, a $10,000 annual research expense fund, up to $1,500 for one-way travel to Pasadena, and eligibility for Caltech health and dental benefits. Fellows will be hosted and mentored by one or more Division professors.
Applications must include a CV, publication list, one-page research statement, and three reference letters. The deadline is November 6, 2026. Apply through the Caltech application portal.
