My research focuses on the conservation and evolutionary consequences of ecological interactions between amphibians and their pathogens. I have conducted research in Costa Rica, Panama, New York, Virginia, South Carolina, and Arizona. Some of my current projects include: (1) community ecology of amphibian hosts that share the chytrid pathogen, Batrachochytrium dendrobatidis (Bd) and the potential for reservoir hosts; (2) the dynamics of amphibian and non-amphibian hosts of oomycetes that infect amphibian eggs; (3) environmental factors, such as temperature and pollutants, that can change the dynamics between hosts and pathogens; (4) surveying viral and fungal pathogens of amphibians in northern Canada.
