I am an experimental nuclear physicist specializing in nuclear (gamma-ray and neutron) spectroscopy of solar system objects, nuclear astrophysics, and radiation transport modeling. My spaceflight mission experience includes MESSENGER (GRS instrument scientist) and Dawn at Vesta (science team associate). My instrument development experience includes the Engineering Radiation Monitor on the Van Allen Probes, the Radiation Monitor Subystem on the Europa mission, and the GeMini gamma-ray spectrometer being developed under NASA's Maturation of Instrumentation for Solar System Exploration (MatISSE) program. I'm the principal investigator for grants awarded under NASA's Planetary Mission Data Analysis Program (PMDAP), Mars Data Analysis Program (MDAP), and Discovery Data Analysis Program (DDAP). My primary research focus is the elemental composition of Mercury, the Moon, and small solar-system objects (asteroids 433 Eros, 4 Vesta, 16 Psyche, Mars moons). A list of all publications can be found here.
