Dr. Paul de Vos graduated in 1992 from the University of Groningen as immunologist and obtained his PhD in 1996. Since 1996 he is active in several lines of research related to Diabetes. Currently he is the chair of immune-endocrinology and transplantation biology. The de Vos-group based at the University Medical Center Groningen, The Netherlands is multidisciplinary and composed of immunologists, polymer-chemists, and endocrinologists. Research efforts go from basic knowledge of carbohydrates, microorganisms to stimulation of pattern-recognition receptors and related immunological properties. More than 200 peer-reviewed papers has published by the de Vos-group. Polymers used for biomaterials can interact with pattern recognition receptors. By applying tailored-made polymers immunological processes can be changes and disease prevented. Paul de Vos is principle investigator and project leader in Carbohydrate Competence Center (CCC) and is also member of the juvenile diabetes research foundation (JDRF) funded ‘encapsulation consortium’.
