Jeroen Codée (1975) obtained his PhD degree form Leiden University (2004) under the guidance of Prof. Jacques van Boom and Prof. Stan van Boeckel, working on the synthesis of heparin oligosaccharides. After a post-doctoral say in Zurich, at the ETH with Prof. Peter Seeberger, where Jeroen was trained in automated and continuous flow synthesis techniques, he returned to Leiden University as a NWO Veni-fellow to set up a carbohydrate synthesis group within the Leiden University Bio-Organic Synthesis (BIOSYN) department. His research focuses on all aspects of oligosaccharide synthesis and the application of synthetic carbohydrates in chemical glycobiology and glycoimmunology. In particular, he is interested in unravelling the mechanism of glycosylation reactions and construction of complex bacterial oligosaccharides for applications in innovative vaccines and as probes to unravel the machinery of carbohydrate processing enzymes.
