Biography
My research interests centre on understanding the regulation of the adaptive immune system. Specific long-term interests revolve around how T cells can be exploited to enhance cancer immunotherapy and alleviate dysregulation. Currently I have two ongoing projects investigating different aspects of adaptive responses in cancer. The first is seeking to characterise CMV-specific T cells after bone marrow transplant in order to improve patient monitoring, a collaboration with Southampton University Hospitals Trust (see here for a video describing the project: https://www.youtube.com/watch?v=WiNBCm1uSHk). The second project is investigating the immune microenvironment in Waldenstrom's macroglobulineamia (a type of lymphoma) patients to understand how current treatment approaches impact disease; this is in collaboration with University Hospitals Dorset. Other ongoing research projects are investigating the role of T cells in infertility and exploring the impact of our environment on immune function in humans and other species...
To facilitate biomedical research at BU I am Academic lead for the Biobank, a member of the Human Tissue Authority Licencing committee internally and a member of the Wessex Immunology Group and British Society for Immunology externally.
