My main research is focused on the foodborne pathogen Campylobacter spp. I have built up a body of work on this pathogen which includes detection, isolation and confirmation from naturally contaminated samples, detection of antibiotic resistance and molecular characterisation using conventional PCR, quantitative real time PCR, pulsed field gel electrophoresis, denaturing gradient gel electrophoresis, flaA short variable region sequencing and multi locus sequence typing. More recently I have been using Whole Genome Sequencing to detect difference in strains that colonise the gut and/or liver of chickens. I also have many years’ experience of chicken infection studies. I have used in-vitro and in-vivo to examine the immunological response of chickens to a challenge with Campylobacter, the effect of diet on the carriage of Campylobacter spp., co-infection with other bacterial pathogens and feed and water interventions to reduce Campylobacter spp. colonisation.
I have previously supervised BSc and MSc project students and been an advisor to PhD students. I am a peer-reviewer for several high impact journals.
