I am interested in surface processes on planetary bodies throughout the solar system, especially those processes which affect, or are driven by, planetary ices. Mostly I investigate the formation and modification of the martian polar and mid-latitude ice deposits and their interaction with climate. Currently, I am also working on simulating the evolution of cratered landscapes, the behavior of surface frosts on large asteroids such as Ceres and the topography and lake-shorelines of Saturn's moon, Titan.

The background image is of Phoebe, a moon of Saturn. It was acquired by the Cassini spacecraft in June of 2004. See here for the original image and more info.
