My research interests lie at the interface of the Earth and Life Sciences. I investigate ocean-cryosphere-biosphere interactions in the Arctic region from seasons to millennia, using biogenic tracers preserved in marine sediment records as a primary tool. Current research topics in my group include 1) Holocene palaeoceanography/paleoecology 2) Discovery and development of proxies for Arctic climate and environmental change (e.g. sedaDNA); 3) Cryosphere change impacts on arctic marine ecosystems
