After receiving his Medical Degree (cum laude/ with Honour) from the University of Groningen in 1999, he finished his training as a paediatrician at the VU Medical Center in Amsterdam in 2006. His fellowship paediatric rheumatology-immunology was completed in 2008 in Utrecht. He worked as a paediatric rheumatologist for 3 years in both Reade and the VUmc in Amsterdam. In 2011 he came to work in the largest Dutch group of Pediatric Rheumatology / Immunology based in Utrecht. He is currently doing a Master in Epidemiology at Utrecht University.

His research (and that of his PhD-students) focuses on comparative effectiveness and safety of drugs, treatment-strategies and eHealth in juvenile idiopathic arthritis (JIA). He also analysed the effects of mesenchymal stem cells in JIA-patients. Furthermore he is researcher and member of the Steering Committee of the international Pharmacovigilance database Pharmachild (over 9000 JIA-patients who have contributed their clinical data and thousands of blood and synovial samples) and is co-P.I. of the UCAN CAN-DU project (JIA project involving all academic paediatric rheumatology centers in the Netherlands and Canada).

He is (co-)author on more than 60 scientific articles in peer-reviewed journals, mostly related to JIA. He is (co-)applicant on multiple successful research grants (e.g. UCAN CAN-DU. Real-life integration of innovative precision medicine strategies into care provision will forever transform the care of children with arthritis in our countries and beyond. Canadian Institutes of Health Research/ The Netherlands Organisation for Health Research and Development [ZonMw]/ Dutch Arthritis Foundation funded  €5,500,000).

He is council member of the Dutch Association for Paediatric Rheumatology, council member of the Pediatric Rheumatology International Trial Organization and chair of the Pharmacovigilance and Targeted Therapies Working Party of ERN-RITA.
