Professor Vivianne Malmström leads research group at Karolinska Institutet at the Department of Medicine, Division of Rheumatology. The Malmström research group focuses on studying the malfunctioning adaptive immune system in patients with rheumatic disease. The prototype disease under investigation is rheumatoid arthritis, but we also study SLE, ANCA-vasculitis and myositis.

They strive to understand both the magnitude and ‘flavour’ of the underlying autoimmunity in the different disease settings. Their approaches span from cellular immunology and structural biochemistry to single cell transcriptomics.
