My scientific interests span the fields of geology, paleoclimatology, and archaeology. To investigate this broad range of topics, I apply a combination of geochemical techniques and modeling. This interdisciplinary approach allows me to investigate a variety of questions. What was atmospheric circulation like during a warmer-than-present world? How did the land, ocean, and atmosphere interact over the last 5 million years? Can we identify new feedbacks between the climate system and ever-changing landscapes? How and when did humans begin to domesticate animals?
