About me
My research focuses on how climate warming changes carbon and nitrogen cycling in the Arctic, and how this affects large-scale greenhouse gas fluxes. Arctic ecosystems store large amounts of organic carbon and nitrogen within continuously frozen permafrost soils that are rapidly thawing as a consequence of global warming. Previously frozen carbon and nitrogen consequently 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”);
- Nitrogen cycling and N2O production on the Arctic Ocean shelves;
- Transfer and degradation of permafrost-derived organic carbon along the land-river-ocean continuum, and impact on Arctic Ocean acidification.
