Global change, from habitat alterations to changes in climate, causes distributional shifts in species composition and species extinctions. My major goal is to quantify how species functional diversity and functional composition affect important ecosystem processes, such as organic matter decomposition and biomass growth. Most of my work is focused on aquatic ecosystems, both freshwater and marine. 

Key areas of work within ecology:
- Community and ecosystem ecology
- Meta-ecosystems
- Biodiversity, ecosystem functioning, energy and nutrient flux across ecosystems 
- Freshwater and marine ecosystems

I am interested in understanding how the movements of nutrients and organisms shape ecosystems. Because modern industrialized societies heavily impact many of those movements - through accelerated species exctinctions, habitat loss, pollution, and climate change, among others - it is also important to understand how modern human activities shape our planet. 

In my group we focus a lot on studying movements of nutrients and organisms across ecosystems in Arctic Norway. Lately I have started a new research line that assesses fluxes of nutrients across national borders, to better understand how unequal ecological exchange is shapping our planet. 

I am currently co-leading the Catchment-to-Coast programme (together with my colleague Amanda Poste). This is a 5-year research programme that aims at better understading the links between freshwater, terrestrial, and coastal ecosystems in the Arctic under climate change.
