Lunar science: Remote compositional analysis using spacecraft and telescopic multi-spectral data. Science questions focus on formation and evolution of the lunar crust and character and diversity of mare basalt types. Craters and large basins are used as probes to the interior. The character and evolution of the enormous South Pole-Aitken Basin continues to be under detailed investigation.
PI, Moon Mineralogy Mapper (M3): Principal Investigator for an imaging spectrometer (0.4-3.0 µm) to characterize and map the mineralogy of the Moon at high resolution. M3 will be flown on the Indian Chandrayaan-1 mission to the Moon in early 2008.
Laboratory spectroscopy experiments: Measuring and modeling the interaction of visible to mid-infrared radiation with geologic materials. Development of quantitative methods for extraction of compositional information. Includes measurement and analyses of lunar samples and meteorites as well as Mars analogs and terrestrial materials.
Space weathering: Determining the processes responsible for altering materials in the space environment and measuring the effects of these processes on geologic samples. Working to derive the evolution of the regolith.
Dawn Science Team: Participation in planning the mission to study the large asteroids Vesta and Ceres in detail. Principal responsibilities include oversight and integration of remote compositional measurements and development of links to meteorites and understanding of early solar system processes.
Asteroid - meteorite links: Evaluating observational and experimental data to identify asteroidal source bodies for diverse meteorite types. Science focus is on evolution of the early solar system.
International collaboration: Quantitative modeling of lunar sample data and geologic analysis of multi-spectral images with scientists at Kharkov University, Ukraine. Spectroscopic analysis of lunar soils, meteorites, and meteorite analogues with several scientists from the Vernadsky Institute, Moscow. Promoting and assisting in planning international exploration with Europe, Japan, Russia, and India.
