Research Interests

I am interested in determining the immunological changes associated with disease course in a range of diseases using the combination of next-generation sequencing, experimental techniques and computational analyses. By probing genetic diversity of immune receptors in B- and T-cell populations, I aim to answer key questions about disease dynamics in autoimmune disease, infectious disease, immunodeficiency and leukaemia, thus potentially opening avenues for new therapeutic targets, as well as potentially providing a new platform for disease monitoring to improve patient outcomes and quality of life.


We have developed highly sensitive molecular frameworks for understanding the dynamics of B- and T-cell populations during infection and malignancy, achieved by high-throughput sequencing, and the development of novel computational methods. Projects range from understanding immune responses in human immunodeficiency virus (HIV), Simian immunodeficiency virus (SIV), Hepatitis B and Hepatitis C in humans and model organisms, to understanding leukaemogenesis in chronic lymphocytic leukaemia (CLL) and acute lymphocytic leukaemia (ALL), and development of diagnostic tools for determining B-cell and T-cell clonality. The work involves multiple national and international collaborations. PhD supervisors: Prof. Paul Kellam and Prof. Allan Bradley, Wellcome Trust Sanger Institute.
