Disease Ecology

We work on a variety of disease systems. In the past, the community ecology of Lyme disease and tick-borne pathogens was a major focus. Currently we work on how deforestation in the southern Amazon interacts with biodiversity (hosts), vectors, and pathogens to influence disease risk to humans. Our primary focus is Leishmaniasis, which is transmitted by sand flies, but we also work with other pathogens. In addition, we work on developing and testing genetic tools to detect the fungal pathogen that causes white-nose syndrome in bats. We have recently started a project geared toward the treatment of infected bats in the field.
