The research in the Section of Molecular Immunology focuses on investigating the fundamental processes underlying immune responses, in particular, the development and maintenance of T cells.

A focus of research within the Section is also the immune response to dengue virus infection, which is one of the biggest threats to public health in a number of developing countries. Research within the Section has demonstrated that antibodies may contribute to the disease process during the secondary infection, which tends to be more severe.

The Section is supported by funding from the Wellcome Trust, Medical Research Council, Leukaemia Research Fund, the Biotechnology and Biological Sciences Research Council, the National Institute of Health (NIH) and European Commission Seventh Framework Program.

In addition to its research programme, the Section of Molecular Immunology is responsible for delivering the Imperial College MSc in Immunology, and is a core contributor to the intercalated BSc in Immunology and the Immunology short course for clinicians and scientists.
