Reconstructing past climate and environmental change

Our research group works on reconstructing past climate and environmental change with a focus on marine records from the North Atlantic and Arctic regions. Our group studies the interactions between the oceans, the atmosphere, the land surface, and the cryosphere, by performing multi-proxy analyses of high-resolution sedimentary deposits. Our analytical techniques range from classical micropaleontology to inorganic and organic geochemistry. We also apply computational approaches, like time series analyses, to decipher patterns and research climate drivers. For more information on our active projects, see below.
