My current research focuses on the understanding of the immune response mounted by chickens and turkeys following infection with Histomonas meleagridis and the use of this information for rational vaccine development. Other research that I am involved in focuses on: (1) understanding of the protective immune response induced by candidate vaccines against Campylobacter in chickens; (2) refinement and testing of vaccines against Campylobacter in chickens; (3) understanding molecular mechamisns of pathogenesis of food-borne zoonoses such as avian pathogenic E. coli infections in chickens, Salmonella infections in chickens and cattle; (4) prevalence of food-borne bacterial infections and antimicrobial resistance in game, e.g. Campylobacter in pheasants and E. coli (including O157) in deer.
