Rheumatoid Artrhritis
Treatment
Optimizing treatment of chronic arthritides
Rheumatic immune-related adverse events
onco-immunology
My main research interests are:
- to understand the immunological mechanisms behind multidrug resistant rheumatoid arthritis and to improve treatment of this subgroup of patients
- to optimize the use of already existing antirheumatic treatments and treatment strategies for early and established rheumatoid arthritis by conducting several investigator-driven clinical trials
- to understand the immunopathology, clinical phenotype and optimal treatment strategies of chronic arthritis induced by immun-checkpoint inhibitor treatment
