Ongoing project areas in my laboratory include:

  • the use of probiotics to mitigate chytridiomycosis in amphibian populations
  • the community ecology context of infectious diseases in wildlife
  • conservation of the rare Cow Knob salamander (Plethodon punctatus)

Our research is currently funded by the National Science Foundation and supported by the USDA Forest Service.
