My current research interests include the geology, geophysics, and geomorphology of the terrestrial planets and small solar system bodies (asteroids, comets, and planetary satellite), specializing in impact cratering related processes. This interest has led to multiple lines of scientific investigation, using spacecraft observations combined with analytical and numerical modeling techniques to answer outstanding questions regarding the surface processes, internal structure, and developmental history of these objects.
Currently funded research topics:The nature of impact-produced seismic signals on Mars
The production and distribution of secondary craters from large impacts
The magnitude of the Late Heavy Bombardment in the inner solar system
Near-Earth asteroid surfaces and structures from radar-derived data
Spacecraft mission involvement:GRAIL (2010-present): gravity data analysis and modeling
Stardust-NExT (2006-2011): Science Team member
Cassini-Huygens (2005-2010): Imaging Team data analysis
Deep Impact (2001-2007): Associate Science Team member
