Jessica Barnes

Assistant Professor

Jessica Barnes will be joining the LPL faculty as an Assistant Professor in the Fall of 2019. She is currently a postdoctoral fellow at NASA’s Johnson Space Center. Jess’s research centers on understanding the origin and evolution of volatiles in the inner Solar System. She utilizes a combination of electron microscopy and high-resolution secondary ion mass spectrometry to study extraterrestrial materials. Jess’s research background is in lunar mineralogy and geochemistry. Most recently she has been using coordinated electron and ion beam studies of meteorites to investigate the evolution of water in the Martian crust and to assess the inventories and origins of volatiles on primitive chondrite and achondrite parent bodies.
