My research focus is on nutrients, and understanding the cycling among plants, soil and microbes in interaction. However, it is central to understand the environmental consequences for our nature, and to understand the consequences of human made climate change, global warming and elevated CO₂. My interest is for both managed and natural ecosystems, as we need healthy soils, high biodiversity and re-establishment of ecosystems after extreme disturbance such as for example wildfire, Arctic winter heatwaves, and extreme re-establishing of ecosystems post-mining.

Ecosystem nitrogen cycling is investigated by stable isotope techniques using our new stable isotope facility (IRMS): ¹⁵N tracing through soil microbes and plants; specifically soil nitrogen cycling is studied: depolymerization, mineralization, nitrification, de-nitrification.

Limitation and availability of macro nutrients ex. phosphorus and also micro nutrients is assessed by our new ICP. Soil and ecosystem storage and release of carbon is assessed at the new TOC, the new Respirometer and infrared gas-analyser in the field, enabling stoichiometry and balance analysis.
