Research Interest
I am broadly interested in ocean biogeochemistry, and how ocean biogeochemistry interacts with the climate system. My focus lies on including microbial processes into biogeochemical ocean models, in particular heterotrophic microorganisms that remineralise organic carbon to CO2. I combine ecological theory and biogeochemical modelling, using a network perspective to address questions on microbial and chemical diversity.
Current Projects
- The Cluster of Excellence „The Ocean Floor”: Receiver (DFG)
- Drivers behind the DOC distribution in the global ocean – present and future (MWK)
- Interaction networks of phototroph-heterotroph microbial communities (funded by Simons Foundation, USA) as part of the CBIOMES project
- Quantifying coastal emissions of carbonyl sulfide (DFG & NSF)
