Summary of Expertise
Planetary collisions and origins
Comet and asteroid geophysics
Surface processes
The Moon
Near-Earth objects
Solar system exploration
Research Interests
Asteroid and comet geophysics, Mars surface evolution, planetary collisions of all kinds, and the origin of planets, satellites, meteorites and their parent bodies. I am also interested in spacecraft exploration of comets and asteroids, and zero gravity experiments to understand the rheology and petrology of small bodies and accreting planetesimals.
