Professor Bridget Wills is Professor of Tropical Medicine at the Centre for Tropical Medicine and Global Health, University of Oxford, United Kingdom (UK), and Vice-Director of the Oxford University Clinical Research Unit (OUCRU) in Ho Chi Minh City, Vietnam. After broad training in general medicine, paediatrics and infectious diseases in the UK and Malawi, Dr Wills joined OUCRU in 1997. She has been based in Ho Chi Minh City since then, where her primary focus is on clinical dengue research, in particular work to improve diagnosis, classification, and management of dengue. As the Head of the Dengue Research Group, she coordinates a multi-faceted programme of research, based around pivotal randomised controlled intervention trials for dengue integrated with observational studies aimed at a) elucidating the underlying pathogenesis of the vasculopathy that is the hallmark of severe disease, b) understanding transmission dynamics and local and regional disease epidemiology, and c) defining immunological responses to natural infections. She also works on other severe paediatric infections common in the Southeast Asian region, including enterovirus 71 related hand foot and mouth disease, Japanese encephalitis, hepatitis B and neonatal tetanus.
