Objective: Biogeochemical cycles and transport pathways of C and N in the soil-plant-atmosphere continuum with a current focus on Arctic. Activities: ● Emissions of greenhouse gases (GHG; CO2, N2O and CH4), C-sequestration and soil nitrogen cycling in response to management and climate ● Experiences with work in small-medium laboratory scale installations and in large scale, complex field experiments ● Responsible for the stable isotope facility at Center for Permafrost (Cenperm) at IGN.
