I am a researcher at the Geography Research Unit, University of Oulu. I am a member of Physical Geography Research Group (PGRG), where I lead Macrophyte Biogeography Lab (MBL). I am PI of two research projects: Improved geodiversity information in assessing and conserving biodiversity (iGEOBIO) and Exploring geographical mismatch between supply and demand of ecosystem services using big and open source data across high latitudes (AccESS).
