I am a geologist with a methodical focus on inorganic geochemistry of marine deposits. My work encompasses modern as well as ancient depositional systems, from the Holocene back to the Paleozoic. I am especially interested in sedimentary systems of the high northern latitudes as well as hotspots of carbon burial. My current research can be categorised into the following aspects: 1. Diagenetic processes and benthic fluxes in modern marine sediments. 2. Present and past oxygen-depleted marine environments. 3. Biogeochemical processes in the modern and past Arctic Ocean. 4. Coupled biogeochemical cycling of C, S, nutrients and metals.
