Centre for biogeochemistry in the Anthropocene

I am the leader of Centre for biogeochemistry in the Anthropocene (CBA). CBA is a joint operation between the Department of Biosciences, Geosciences and Chemistry. Our interdisciplinary team studies interactions and feedbacks between climate, carbon cycling and ecosystems in northern latitudes.
