Research interests
My research interests involve studying the population genetics of bacterial species to gain a better understanding of their ability to diversify and occupy new hosts/niches and how this can alter over time. Campylobacter is the leading cause of foodborne gastroenteritis world-wide and the main source of infection in humans is associated with undercooked, contaminated chicken. Understanding the ecology and evolution of microbes is integral to implementing control strategies that limit infection. A core part of my PhD research has been to utilise genomics in order to design a vaccine for the control of Campylobacter infection in poultry.
