While the general focus of our research is to improve our understanding of ice sheet change in response to climate, we are also interested in obtaining a basic knowledge of how ice sheets work. This includes Earth's great ice sheets and other ice sheets in our solar system (e.g. Mars & Europa). This is accomplished by obtaining detailed information about ice sheet boundary conditions and observations of ice sheet change using a variety of field-based research tools and remotely sensed data.

We address the following challenges using records from select sedimentary archives (lake sediments, marine sediments, speleothens, corals) and analytical approaches (stable isotopes, biomarkers) in state-of-the-art science facilities (inorganic and organic chemistry).
