Research Focus

The ecology of infectious diseases and their hosts at the interface of wildlife, domestic animals and people. Major areas of research include zoonoses (avian influenza viruses, West Nile virus), veterinary parasitology (Psoroptes mites, Mesocestoides tapeworms), and conservation biology (bighorn sheep, mountain lions).
