I lead or co-lead several projects related to my research interests, including the Environmental Pathway of Infection in Children (EPIC) project which aims to understand childhood exposure to enteric pathogens in Mozambique, Brazil, and the United Kingdom. In Mozambique, this work continues a 10-year collaboration with the National Institute of Health, and is nested within the SaniVac trial, which aims to assess the role of sanitation access on oral rotavirus vaccine immunogenicity and the rate of acquisition of enteric infections during early childhood. I am the co-PI on a study of oral cholera vaccine (OCV) in eastern Democratic Republic of the Congo (DRC), in collaboration with Johns Hopkins University, which aims to measure the impact and effectiveness of OCV in an endemic setting of Uvira, DRC, as well as to characterise household-level transmission patterns of Vibrio cholerae. I am the laboratory lead for several studies across sub-Saharan Africa that use tools including TaqMan Array Cards to better understand the role of exposure to enteric pathogens among children suffering from severe acute malnutrition, as well as to explore food-related pathogen exposure among children.
