The wealth of information returned by the Galileo,
Cassini, and Mars Global Surveyor spacecraft
continues to advance theories of surface formation
and evolution. Our research focuses on the
geomorphological evidence for processes which have
shaped the surfaces and interiors of solid bodies
over the age of the solar system. Comparative
studies of planetary systems are utilized to
understand the geological histories and petrology
of icy bodies (Europa, Ganymede, Callisto, Triton,
Pluto/Charon) and other planets (Mars, etc.).
Geochemical and geophysical modeling of the
internal processes shaping the surfaces of Mars,
the Galilean and Saturnian satellites, and other
objects are combined with remotely sensed data
sets to provide qualitative and quantitative
understanding of the forces which shaped these worlds.
