Chris H Okubo, PhD
Deputy Astrogeology Science Center Director and Research Operations Lead.
Chris helps to oversee management of the Astrogeology Science Center. He currently serves as chief for the Research Operations branch of the Astrogeology Science Center and continues research activities as time permits.
Chris has studied thermal characterization of pit craters on Kīlauea volcano, Hawai‘i, high resolution structural mapping in west Candor Chasma, Mars, stability analyses of Martian “gullies” and investigation of formation mechanisms and geotechnical assessments of planetary soils and rock masses. He has also studied fracture-controlled fluid flow on Mars, strain localization in porous rocks and implications for deformation band formation, structural analysis of thrust fault-related folds on Mars and satellite monitoring of active terrestrial volcanoes.
