Research Interests

Arctic ecosystems store large amounts of organic carbon within continuously frozen permafrost soils, but are also strongly affected by global warming. Permafrost thaw thus promotes the mineralization of soil organic carbon to carbon dioxide and methane, two strong greenhouse gases that can further accelerate global warming in a positive feedback loop.

My research on arctic carbon cycling specifically focuses on

  • the transfer of organic carbon from permafrost soils into rivers and oceans, and its decomposition,
  • the vulnerability of organic carbon in inundated permafrost soils (subsea permafrost),
  • the effects of increasing plant productivity on organic matter decomposition in the seasonally thawed active layer of permafrost soils (priming effects), and
  • interactions of carbon and nitrogen cycling during decomposition.
