Dr. Laurie Barge, JPL Research Scientist in Astrobiology, is seeking a postdoc to work on astrobiology and geochemistry research in the Origins and Habitability Laboratory at JPL. The candidate will work with Dr. Barge on analysis of hydrothermal vent chimney samples that were retrieved from a recent cruise to an ocean world analog field site, and conduct laboratory simulations of prebiotic chemistry in hydrothermal vents on early Earth.
