Professional background

Maria Leandro is consultant rheumatologist at UCL Hospitals and is an honorary senior lecturer at University College London.

Maria studied medicine at Universidade Nova de Lisboa and trained as a rheumatologist at Hospital de Santa Maria in Lisbon, Portugal. She was previously a research fellow at University College London and awarded a PhD for her work on the mechanisms of disease relapse in rheumatoid arthritis following B cell depletion therapy.

Maria's key interests are in inflammatory arthritis, rheumatoid arthritis, B cell directed therapies in autoimmune diseases and role of B cells in the pathogenesis of autoimmune diseases.

Research interests

  • Inflammatory arthritis
  • Rheumatoid arthritis and B cell directed therapies in autoimmune rheumatic diseases.
