Scientific Interests

In the broadest terms, I am curious about how Earth's surface has changed through time.  Water, soil, rocks, the atmosphere and life all interact with each other in complex ways, and all have been recently (in geologic time) altered by human activity.  In order to create a sustainable predict the effects of our actions in the future, we measure current conditions and find ways to quantify historical and pre-human impact - or "natural" - conditions, which is one of the biggest challenges for environmental scientists today.
