“The central themes that run through my research are the processes that modify solid surfaces and the spatial and temporal scales that control environmental processes on the Earth. Because surfaces lie at the interface between the solid interior of a planet (from the shallow subsurface to the deep interior) and the fluid exterior (atmosphere, hydrosphere, etc.), their composition and morphology record the interesting interplay between interior and exterior processes.”

This artist’s impression shows how Mars may have looked about four billion years ago. The young planet Mars would have had enough water to cover its entire surface in a liquid layer about 140 metres deep, but it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 kilometres.
