Francis McCubbin is a Research Scientist and Astromaterials Curator at NASA's Johnson Space Center in Houston, TX. His research interests include determining the abundances and roles of volatiles (C, H2O, F, Cl, S) in magmatic systems within terrestrial planetary bodies and their consequences for the petrological evolution of Mercury, Earth, Moon, Mars, and asteroids. This work is accomplished through a combination of experimental petrology, mineralogy, and analysis of astromaterials using a variety of micro-beam analytical techniques.
