My research addresses the impact of climate warming on biogeochemical cycles in terrestrial and aquatic ecosystems, and how this affects large-scale greenhouse gas fluxes. A special focus of my work lies in the Arctic that is rapidly warming and stores large amounts of organic carbon and nitrogen within continuously frozen permafrost. With permafrost thaw, more and more carbon and nitrogen become accessible to microbial decomposers, resulting in the production of greenhouse gases that can further accelerate global warming.

Current research focus areas:

• Effect of increasing plant productivity and vegetation shifts on soil organic matter decomposition in permafrost systems (“priming effect”);
• Carbon-nitrogen interactions in permafrost soils and feedback on plant productivity;
• Greenhouse gas release from inundated permafrost on the Arctic Ocean shelves (“subsea permafrost”);
  
• Methane release and oxidation in the Arctic Ocean;
• Transfer and degradation of permafrost-derived organic carbon along the land-river-ocean continuum, and impact on Arctic Ocean acidification.

My research group uses a wide range of approaches to address these questions. These include field campaigns (e.g., to the Russian Arctic Ocean in 2020, and to Inuvik, Canada, in 2022-2026), laboratory experiments, biomarker analyses, stable isotope analyses (including compound-specific analyses), radiocarbon dating, large-scale databases and modelling.
