Michael Duffy

Associate Professor



Bailey Hall 163


Academic interests

  • Parasitology
  • The parasites of wildlife and aquacultured fish
  • Wildlife Diseases

Current projects

Research serves to integrate parasite diversity and life history, aspects of the ecology of parasitism of wildlife, mechanisms of infection, epidemiology, host responses to infection, pathology, and parasite identification and diagnosis (morphological, immunological, molecular tools).

  • Invasive parasite of American eels - non-lethal diagnostic tools to promote conservation and eel population recovery.
  • Ectoparasitic lice on Atlantic salmon – investigating aspects of environmental change and anthropogenic factors that contribute to infestation. Investigating spatiotemporal aspects of infection and potential multigenerational impacts on salmon.
  • Parasites of fishes - zebrafish as a model host for investigation of immune responses to parasitic organisms.

Courses taught

  • BIOL 4691 Biology of Marine Parasites
  • BIOL 3311 Immunobiology
  • BIOL 4211 Marine Research Experience
