Research Interests

My research focuses on Arctic carbon and nitrogen cycling under changing environmental conditions. 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 becomes accessible to microbial decomposers, resulting in the production of greenhouse gases that can further accelerate global warming.

Specific research focus areas:

  • Transfer and degradation of permafrost-derived organic carbon along the land-river-ocean continuum;
  • Vulnerability of organic carbon and nitrogen in inundated permafrost soils (“subsea permafrost”) to degradation;
  • Effect of increasing plant productivity on organic matter decomposition in the seasonally thawed active layer of permafrost soils (“priming effect”);
  • Nitrogen cycling and N2O production on the East Siberian Arctic Shelf.
