    Teaching

    • Project leader: BioCat (2016-2024). BioCat is a national graduate school in biocatalysis, granted by The Norwegian Research Council. It is established to provide expertise and tools for research and research education within biocatalysis in Norway. The school is open to all PhD-students and their research groups within the field. Biocatalysis is important in many areas including  biomedicine, biotechnology,  microbiology, and (bio)nanoscience.  Additionally, biocatalysis is becomming increasingly important industrial processes and in various diagnostics-, gene- and biotechnologies, and is expected to be important in the transition of the society to a bio-based economy. Six Norwegian universities, 4 research institutes and the Industrial Biotechnology Network Norway, constitute the BioCat consortium. This collaboration represents a unification of many strong research groups, giving the students great access to both the expertise, facilities and training offered by the Norwegian biocatalysis research community.
