Research interests

I am interested in the areas of research relating to the control of diseases such as gastrointestinal nematodes in humans and livestock. Particularly, I am interested in the following areas;

  • Drug discovery and development for human and veterinary parasitic worms
  • Development of assays to screen for new anthelmintics and to diagnose anthelmintic resistant parasites
  • Understanding the molecular interaction between the host immune response and pathogens
  • Diagnostic development for the emergence of new and existing diseases
