Research topics
I’m a microbial ecologist interested in extreme environments and links between microbial community and ecosystem functioning. After a PhD in plant-soil-microbes interactions in permafrost systems (Dr. Ellen Dorrepaal, Umeå University, Abisko) and a postdoc in plant-food web-biogeochemistry interactions in sub-Arctic tundra soils (Dr. Eveline J. Krab, SLU, Uppsala), my current postdoc focuses on improving the PrimeSCale model.
PrimeSCale aims to explicitly incorporate rhizosphere priming effects in predictions of carbon fluxes in the permafrost region, by combining datasets from earlier modeling efforts (e.g. active layer thickness, soil carbon and nitrogen, GPP) and data derived from new meta-analyses (rhizosphere priming effect, root depth distribution of different vegetation types). Possible improvements to PrimeSCale that will be explored throughout my project include its geographical scope, choice of source data and sensitivity analyses.
In addition I explore microbial functional limitations in permafrost soils, soil fauna effects on microbial communities, and am a co-founder of the ECR long-term mycorrhizal plants removal experiment ALTER.
