Vincent Eijsink obtained an MSc in Molecular Sciences (Biochemistry) from Wageningen University and completed his PhD at the Groningen Biomolecular Sciences and Biotechnology Institute under the supervision of Gerard Venema in 1991. During his Ph.D. studies, focusing on the engineering of protein stability, he was co-supervised by Herman Berendsen, Bauke Dijkstra and Gert Vriend and he had several short stays in the Bioinformatics group at EMBL. In 1993, he moved to what is now called the Norwegian University of Life Sciences (NMBU), in Ås, Norway, where he became a full professor of Biochemistry in 1997. Work on CAZymes started off with work on family 18 chitinases in the late 1990s, resulting in several papers on the structure and function of these enzymes [1, 2]. Current chitin-related work focuses on family 18 chitinases [3, 4, 5] and family 19 chitinases , whereas the group has a growing interest and activity in chitin deacetylases (CE family 4) [7, 8]. Recent research includes CAZyme discovery [9, 10, 11]. The Eijsink group is probably best known for the discovery of lytic polysaccharide monooxygenases (LPMOs) in 2010  (AA family 10) after originally having detected chitinase boosting activity of what we now know is a chitin-active family AA10 LPMO in 2005 . The group demonstrated AA10 activity on cellulose [14, 15] and was the first to describe activity of AA9 LPMOs (AA family 11) on soluble substrates  and beta-glucan hemicelluloses [17, 18]. Recent developments include studies of both AA9 and AA10, addressing topics such as substrate-binding , LPMO activation , and the involvement of hydrogen peroxide in LPMO action [21, 22].
