Research summary
Enteric bacteria are varied and wonderful. Some, like Bacteroides, are friendly and help us to stay healthy while others, like Salmonella, Campylobacter, E. coli and C. difficile, wreak havoc and often give us diarrhoea! My main research interests are understanding how these bacteria interact with their hosts and developing strategies to control pathogenic bacteria.
My current research focusses on Salmonella, which causes disease in humans and livestock. Ongoing projects include developing a live-attenuated vaccine to prevent salmonellosis, investigating alternative vaccine strategies, trying to understand why different types of Salmonella behave differently in different host species and expanding a sequencing methodology I developed to study mixed strain-infections of Salmonella to other enteric pathogens like Campylobacter and E. coli.
