My postdoc project lies at the interface of microbial, soil fauna and ecosystem ecology. More specifically I investigate the links between soil food webs - from bacteria to mesofauna - and biogeochemical cycling of carbon and nitrogen in tundra soils. Experiments within this project intend to pursue a better understanding of the mechanisms regulating CO2 release from warming Arctic tundra systems.

Research

My research focuses on experimental approaches to investigate mechanisms regulating CO2 release from Arctic tundra soils in a warmer world. The Formas-funded project "Living soils in a future Arctic", led by Eva Krab, combines in vitro incubations of permafrost and topsoil - to explore the role of mesofauna in microbial community compositional changes and C-cycling - with soil transplants across an altitudinal gradient - to simulate warming and evaluate associations between soil food webs and C-cycling. Field work takes place in northernmost Sweden in the Abisko region while soils used in incubations were taken either in northern Sweden or northern Alaska.

In addition, I carry on analysis and publication of results obtained during my PhD on plant-soil-microbe interactions in permafrost-affected soils, and I am part of the Abisko LTER experiment.
