Professional background

Professor Michael Ehrenstein is a consultant rheumatologist at UCLH since 1999. His key interests are in new therapies for rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosus and other autoimmune rheumatic diseases. He leads the New Therapies Clinic for inflammatory arthritis at UCLH and has established with colleagues the Early Arthritis Clinic to enable rapid access for patients with rheumatoid arthritis. Michael studied medicine at the Middlesex Hospital, and trained in rheumatology at the Hammersmith Hospital and Addenbrooke’s Hospital, Cambridge.

He was previously an MRC clinician scientist at Cambridge University and the Laboratory of Molecular Biology. He was awarded a PhD at UCL on the pathogenesis of autoimmune rheumatic disease. He has undertaken many roles for NHS England, the British Society for Rheumatology, charities and universities within the realm of rheumatology and advised licensing authorities (MHRA) and commissioners regarding new therapies for arthritis.
