Presentation
I am a researcher in ecophysiology. The focus of my research group is on the ecophysiology of nitrogen use efficiency and plant nitrogen (organic and inorganic nitrogen) availability at the root tip scale in different plant species, under different environmental conditions in different types of soil, primarily in boreal forests.

Research
Insights into sustainable plant nitrogen availability are crucial for tree growth and food production. Further insight to the plant perspective of nitrogen availability is important for finding ways to increase nitrogen use efficiency and decrease nitrogen pollution in managed environments, in a changing climate. Our research approach this from multiple angles and investigates plant physiological as well as soil microbial and soil chemical aspects of this.
We approach this from field experiments to agar plates.
We use microdialysis and apply the method in different ways to investigate plant nitrogen availability (diffusive fluxes, mass flow, reverse dialysis). With this method, sampling is performed at microscale with minimal disturbance of the soil and soil processes.
Our close collaboration with the Swedish Metabolomics Centre and SLU Stable isotope laboratory enables unique expertise in chemical analysis of the root-soil-microbial interface (targeted and non-targeted LC-MS, GC-MS, 15NH4, 15N amino acids).
