Vincent Eijsink


  • Faggruppe dekan

I am originally from the Netherlands, have worked at NMBU since 1993 and am currently Professor of Biochemistry (since 1997). I lead a research group called the "Protein Engineering and Proteomics" (PEP)  group and am a member of the Norwegian Academy of Science and Letters. My research group works with enzymes, proteins, microbiomes, microbiology, bioprocesses and industrial biotechnology. We work with both very basic and more applied issues.

  • I contribute to courses in Experimental Biochemistry (KJB201), Protein Chemistry (KJB310), Proteomics (KJB320) and Applied Biocatalysis and Biorefining (BIO335)

  • Together with Gustav Vaaje-Kolstad, I lead a large research group with several members who have their own projects. Our research is primarily funded by the Research Council of Norway, the EU (Horizon & ERC) & the Novo Nordisk Foundation. We participate in several major initiatives and research centers, such as SFI-industrial biotechnology, FME-Bio4Fuels, SFI-Foods of Norway, and teh national infrastructure platforms NorBioLab (biorefining and enzymology) og NAPI (proteomics).
