My research focuses on understanding the immunological mechanisms which drive the development of autoimmune diseases, such Rheumatoid Arthritis and Inflammatory Bowel Disease. We explore the role of innate and adaptive immunity in the pathogenesis these diseases. 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.

Interested in immune dysregulation with drives human autoimmune diseases, such as Rheumatoid Arthritis and Inflammatory Bowel Disease. Specifically my research focuses on Dendritic Cells and T cells specifically within the inflamed tissues and explores the contribution of metabolism, maturation and checkpoint inhibitors on their role in disease pathogenesis
