Research Interests

My research focuses on understanding the impacts of diseases on wildlife populations and the potential for wildlife species involvement in diseases of agricultural or public health importance. Current projects are focused on avian influenza virus ecology in wild birds, parvoviruses of carnivores, retroviruses of wild turkeys, chronic wasting disease, and mange in black bears.
