Biography
My research focuses on understanding the immunological mechanisms which drive the development of autoimmune diseases,such Rheumatoid Arthritis. We explore the role of innate and adaptive immunity in the pathogenesis of RA. By using physiologically relevant ex-vivo models, across multiple disease stages, we aim to identify new biomarkers for disease onset, therapeutic response and disease severity. Finally, we collaborate with several pharmaceutical companies, clinicians, translational scientists and patients to maximise the impact of our work and ensure the successful translation of our findings from bench to bedside.
