Personal profile

Research interests

  • Host-pathogen-environment interactions in ruminants and monogastric hosts; use of in situ (broilers), in vivo (sheep, rodents)and in vitro models to study the interactions.
  • Application of molecular methodologies to identify markers for disease susceptibility and environmental predisposition to disease in mammals.
  • Molecular interactions between nutrition and immunity to gastrointestinal nematodes in small ruminants.
  • Plant-based control strategies for endo- and ecto-parasites in ruminants.
  • Improving gut health in poultry to reduce the risk of zoonotic disease.
  • Improving gut health in broilers via genotype x environment interactions for improved efficiency and health.
