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 i ce deposits. Currently, I am also working on concentration of volatiles in the polar craters of the Moon and Mercury and on the behavior of surface frosts on large asteroids such as Ceres.
