Tracie is currently working as a joint postdoctoral research fellow at the Wildlife Conservation Society (WCS) and the Center for Infection and Immunity.  She conducts amphibian chytrid screening for the zoological collection and various WCS field-based research projects, and she is training at CII in advanced technologies for pathogen detection.  Her interests include:

Climate change, chytridiomycosis, and amphibian decline
Avian malaria
Diagnostic screening and identification of emerging and zoonotic pathogens in wildlife
Macrophage biology, innate immunity, and apoptosis
