Biography:
I joined the Biology program at Carroll University in 2013. My research mainly focuses the effects of emerging infectious diseases in ectothermic hosts, particularly diseases transmission among lower vertebrates (Fish, amphibians, and reptiles) and ecosystem effects of species extirpations. Emerging infectious diseases have been identified as one of the most important factors responsible for aquatic ectothermic organisms declines, and the increasing presence of infectious diseases constitutes a growing threat to global biodiversity and ecosystem function.
