His research is focused on using laboratory spectroscopic techniques and sophisticated light scattering models to enable more quantitative interpretation of spectroscopic data sets. This work includes using laboratory visible/near-infrared reflectance, thermal infrared emission, and Raman spectroscopies, both on remote sensing platforms and in the laboratory, to determine the composition of geologic materials on the surfaces of the Moon, asteroids, Mars, and its moons. He is a Co-Investigator on Diviner Lunar Radiometer Experiment, which has been orbiting the Moon since 2009. In 2012, he was awarded the National Science Foundation Early Career Award. He is the Principal Investigator of the $5.5M Remote, In Situ, and Synchrotron Studies for Science and Exploration (RIS4E) team, which is part of NASA's Solar System Exploration Research Virtual Institute (SSERVI)
