Research Interests

Arctic climate change, previous warm periods in the high latitudes, lake biogeochemistry, lake sediment reconstructions


My primary research focus is reconstructing paleoenvironments from high latitude sites using lake sediments. I use a wide range of proxies, ranging from traditional sedimentological techniques to novel organic biomarkers. My recent research has focused on pairing paleoclimate reconstructions with records of human presence in a landscape to discern how human populations (such as the Norse in Greenland) have responded to shifts in climate. For my post-doc at CU Boulder I am investigating temperature changes during past interglacials (MIS 5 and 7) using biomarkers extracted from lake sediments on Baffin Island. Broadly I am interested in Arctic climate change and how the high latitudes affect global climate.
