Since 1996, our research in the Arctic and alpine
regions reaches across the globe.
I manage the research infrastructure and research-based teaching platform. I also run our public outreach program. My research interests include how life history events, such as phenology, in Arctic and alpine plant and animal species are shaped by the environment. Further how climate change effects resilency of these ecosystems.
I am fascinated by their characteristic plant communities and by the plants’ abilities to survive harsh conditions through manipulation of their neighbours and their microenvironment.
When environmental degradation causes an ecosystem to pass a tipping point, the damage is difficult or impossible to repair. This has adverse consequences for human well-being including desertification, toxic algae blooms, and fisheries collapses. I investigate tipping points in forest lakes.
I’m an environmental scientist, researching issues with high societal values, rather than on traditional scientific disciplines. As a result I try to mix research tools from various research fields such as physical geography, paleolimnology, soil science and ecology.
My research aims at creating a new framework for understanding, quantifying and predicting the regional-scale sediment carbon sink in high latitude lakes, and its sensitivity to climate change.
Special focus within my research lies within studying the importance of organic matter (humic substances) and nutrients (nitrogen and phosphorus) for lake ecosystem productivity and food web structure.
