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.
