Corliss Kin I Sio is a geochemist working at the intersection of isotope geochemistry and experimental petrology. She is interested in the formation and evolution of planetary bodies in our solar system. During her PhD at the University of Chicago and postdoctoral fellowship at the Carnegie Institution of Washington, Corliss developed a toolbox of methods to constrain the thermal evolution of volcanoes, by studying isotopic profiles in erupted crystals. Corliss joined the Chemical & Isotopic Signatures group at LLNL in November 2016, and has since worked on dating the formation of the Moon using samples returned from the Apollo missions. She is currently developing techniques to measure the stable Rb isotope compositions of lunar rocks in order to elucidate the origin and budget of volatiles on the Moon. She also works to further the nuclear forensics goals of LLNL, including the development of 3-D printed rocks for use in technical nuclear forensic exercises and to assess their suitability as standard reference materials for in-situ analyses.
