At Trinity, I tutor second-year medical students in Principles of Pathology and Psychology for Medicine and second-year Biomedical Sciences students in Immunology and Microbiology. For the third-year courses in Medicine and Biomedical Sciences, I tutor the Infection and Immunity options. I also teach immunology to second and third year Biochemistry students. At the faculty level, I lecture on the Principles of Pathology course for second-year Medicine and the FHS (Final Honour School) course in Immunity. I also give lectures for a course in Immunology in the Department of Biochemistry.

For my undergraduate teaching, I received Teaching Excellence Awards from the Medical Sciences Division in 2008, 2013 and 2019 and was shortlisted by the Oxford University Students Union in 2016 for the award of ‘Outstanding Tutor in the Medical Sciences Division’.

My teaching for graduate students includes MSc courses in Integrated Immunology and Experimental and Translational Therapeutics. I have also supervised eight research students to the successful completion of their DPhil projects.

I began my research career in Oxford, where I studied for a doctorate in the Nuffield Department of Surgical Sciences, focussing on the dual role of dendritic cells in allograft rejection and immunological self-tolerance. I subsequently spent five years as a Post-doctoral Fellow in the Department of Pathology, University of Cambridge, investigating the aetiology of autoimmune disease, but returned to Oxford in 1995 to take up a post at the Sir William Dunn School of Pathology.

My current research continues to draw on my background in transplantation immunology, in order to investigate the nature of the immune response to tissues differentiated from pluripotent stem cells and to develop approaches to the induction and maintenance of immunological tolerance to prevent their rejection. Furthermore, I have developed a programme of research aimed at exploiting the properties of pluripotent stem cells to address unmet medical needs with an immunological basis. Protocols developed in my laboratory for the directed differentiation of dendritic cell subsets from human induced pluripotent stem cells offer an opportunity for their use in immunotherapy for the treatment of a spectrum of disease states from cancer to the lysosomal storage diseases. This intellectual property will form the basis of a biotech spin out company from my laboratory focussing initially on the treatment of colorectal cancer.

The immune system is a double-edged sword: while we cannot live without it, it can prove extremely difficult to tame.
