I am currently working as a research scientist at the Planetary Science Institute, Tucson Arizona. My research focus is planetary sciences particularly small bodies (asteroids and comets). I have used a variety of techniques to learn more about them and what they can tell us about planetary formation, including near-IR spectroscopy, high-precision astrometry and photometry. I have worked on NASA Dawn mission for the last three years during the Vesta phase. Links below will take to specific pages related to my research work.
