Research Focus

I study the ecology and epidemiology of infectious diseases in complex communities. While the majority of systems I study are vector-borne (anaplasmosis, Lyme disease, mange, plague, et al.), I and my collaborators also are involved in applied infectious disease ecology problems in other systems including chytridiomycosis in frogs and salamanders, multiple-host transmission dynamics of reptile diseases, and disease in coral. Overall, we aim to understand how community complexity contributes to disease persistence and emergence, and how driving factors are affected by anthropogenic change. Related to this major goal are a collection of projects that include assessing various species' health in the wild and managing disease and other stressors in endangered and threatened species, such as the American pika, the endangered Amargosa vole, and the endangered San Joaquin kit fox.
