John Chappelow - PhD candidate - works on all aspects of impact cratering, from impact
dynamics, to using craters to study the properties and ages of planetary
surfaces. He also studies the planet Mars, with emphasis on the Hematite
Region of the planet, which is soon to be visited by a Mars Exploration
Rover (MER) mission. Some of his recent work includes development of a new
method of recovering crater shapes from shadow measurements, construction
of a GUI-based computer program for making crater measurements, and
investigation of the effects of Mars' obliquity-driven atmospheric
variations on its impact crater population.
