Mark Robinson's research interests are currently focused on the origin and evolution of planetary crusts, including volcanism, tectonism, and regolith development. Investigations are approached using a variety of remote sensing techniques: multispectral imaging, spectroscopy, stereo analysis, photoclinometry, and geomorphology utilizing datasets from Apollo, Lunar Orbiter, Clementine, Galileo, NEAR, Lunar Prospector, Mariner 10, and MESSENGER.
