My research group investigates Earth’s climate history, primarily through the lens of paleolimnology (the study of lake sediments) and with a focus on the Arctic. Our field and laboratory work aims to uncover the causes and impacts of late Quaternary climate change, and to improve the methods used to reconstruct past climate. Northwestern’s Quaternary Sediment Lab┬áis equipped for diverse analyses of sediments, including scanning XRF and color spectrophotometry, laser particle-size analysis, and studies of microfossils. Current projects are reconstructing Earth’s past using methods ranging from stable isotope analyses of chitin, plant lipids and carbonate to paleoecological assessments of charcoal and insect assemblages to GIS analyses of historical Greenland expedition photos.
