Research interests

I am interested in the ecology and evolution of host-parasite interactions, generally at the level of the immune system.   

I investigate these processes across multiple scales in two mutually dependent systems; laboratory and wild rabbit infections with the bacterium Bordetella bronchiseptica and 2 gastrointestinal nematodes Graphidium strigosum and Trichostrongylus retortaeformis. Broadly, questions I am interested in are:

  • Who infects whom, when and how?
  • What makes them infectious?
  • Finally, how can we intervene and what are the consequences?
