Title: "A persistent and dynamic East Greenland Ice Sheet over the past 7.5 million years”

Short Bio: I am a paleo climatologist who uses the geologic record to decipher the patterns and mechanisms of past changes in climate and ice sheets on decade to million year time scales. This research is guided by a series of overarching questions - how sensitive is the climate to external forcing’s, how are various regions and components of the climate system linked, and how well do models simulate the past? My research group applies various tools to address these questions, including developing geochemical records from several paleo-archives (glacier, marine, and cave deposits), and mining the growing body of paleoclimate datasets to search for large-scale patterns. These approaches can entail work behind the computer, in various collaborators' labs, and in the field from places as far off as the Arctic or as close as New England. I'm particularly motivated by paleoclimate problems that have clear relevance to today. [Current Projects]
