I do research on soil organic carbon, vegetation distribution, vegetation productivity (e.g. GPP, biomass, NDVI), plant-herbivory interaction (voles, lemmings, reindeer) using GIS and remote sensing techniques (satellites, drones and machine learning) in the Arctic and permafrost environments.

I teach geosciences and physical geography at base level as well as geomorphology and GIS/remote sensing at advanced level.
