Overview

If you are a patient, thank you for reaching out to me after seeing the article about our research. It is at an early stage and although we are hopeful that these new cells will be therapeutically valuable, they have yet to be tested and approved for clinical trials. For more support please contact a cancer support group in your local area.

My research focuses on how T-cells recognise and respond to disease, with particular emphasis on the antigens they detect and the T-cell receptors (TCRs) that enable this recognition. A major theme of our work is understanding unconventional forms of T-cell recognition that extend beyond classical HLA-restricted immunity, and exploiting these discoveries to understand and treat human disease.

Our research spans cancer, infection, autoimmunity, transplantation and vaccination, combining fundamental discovery with the development of new approaches to identify disease-reactive T-cells and their targets. We are particularly interested in discovering T-cells that recognise shared features of diseased cells and understanding the molecular mechanisms that allow them to distinguish these cells from healthy tissue.
