Senior Research Scientist, The Planetary Science Institute, Tucson, Arizona

I am a senior research scientist at the Planetary Science Institute in Tucson, AZ. My research focuses on the formation of terrestrial planets in our Solar System and around other stars, especially with regards to the delivery of water and other biologically-important materials. I also study the dynamics and evolution of small bodies in the Solar System, and I am working with the Dawn mission to Vesta and Ceres as a science team associate.
