Our group is in the Planetary Science research area of the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University.  We study the large, solid, rocky and icy worlds across our Solar System through their geophysics and surfaces.  Our work uses data returned by NASA robotic spacecraft missions and numerical simulations.  If these topics interest you as a potential graduate or undergraduate student researcher, please e-mail us to talk about planetary science at Purdue!
