The global emergence of epidemic dengue is partly fueled by an incomplete understanding of the determinants of both immunity and pathogenesis. My laboratory aims to address the critical gaps in knowledge in dengue by positioning itself at the interface between clinical epidemiology, virology and immunology. We combine basic virological and virus-host interaction studies with clinical investigations and experimental medicine, including clinical trials. Specifically, we are interested in elucidating: (1) how antibodies either protect against or enhance dengue virus infection and (2) the factors that determine the outcome of infection or transmissibility and hence explain its epidemiological phenotype. By elucidating these mechanisms, we hope to contribute to the development of effective vaccines and therapeutics.
