The group is interested in the tumour microenvironment of lymphoproliferative disorders especially that of chronic lymphocytic leukaemia (CLL) and related low grade lymphomas. Through the use of in vitro and in vivo models, such as patient derived xenografts, and imaging studies the group studies the effect of the microenvironment on tumour progression and how this may affect new treatment modalities that harness the immune system. Recent work has expanded to look at how the response to infections, such as Covid-19, is impacting these patients.
