The epidemiology, genomics and longitudinal immune response of Shigella infections in Vietnamese children

Stephen is a molecular microbiologist based at the Wellcome Trust Major Overseas Programme in Ho Chi Minh City, Vietnam. He has been there since November 2007 and is the head of the enteric infections research group, which studies the microbiology, genetics, epidemiology and treatment of enteric infections in low-income countries. Focal pathogens include Norovirus, Shigella spp. and Salmonella typhi, the causative agents of diarrhoea, dysentery and typhoid fever, respectively. His current direction combines microbiological, immunological and geographical information to study how organisms are transmitted in urban environments and how this interplay can be used to design and implement vaccination strategies.
