Catherine Dukes, LASP/NMCF
Catherine Dukes directs the Laboratory for Astrophysics and Surface Physics (LASP) and provides expertise in X-ray photoelectron spectroscopy (XPS) for the University of Virginia's Nanoscale Materials Characterization Facility (NMCF). Her NSF and NASA funded research focuses on the interaction of radiation (ions, electrons, and photons) with surfaces and the resulting physical and chemical effects. Our emphasis is on understanding the fundamental physics at work in our solar system, particularly the effects of solar-wind particles on the surfaces of airless bodies such as our Moon, Mercury, asteroids, and comets, by simulating planetary regolith environments in the laboratory. We are part of a consortium of researchers currently preparing to investigate unopened lunar core samples collected during the Apollo 17 Mission near Lara crater and will focus our research on characterization of volatiles in the lunar grain rims.
