Most broadly, I am interested in how and why Earth’s climate has fluctuated throughout the Holocene and Late Pleistocene. My current research is focused on developing high resolution climate records to evaluate the onset, duration, seasonality, and magnitude of abrupt climatic change during the Younger Dryas and 8.2 ka events in Southern Greenland. To create these records, I use stable oxygen and carbon isotope measurements on biological material taken from sediment cores along with measuring the bulk chemistry, lithology, and grain size of the sediment. Reconstructions of abrupt climate change like this are important because they can help improve climate models and provide insight for the future.
