Research in my laboratory focuses on the evolutionary ecology of vertebrates, particularly
the genetic and ecological components of species interactions in amphibian systems.
My focus is on pathogens as factors contributing to the global decline of amphibian
populations, with the goal of understanding the constraining impact of diseases on
My research is directed at understanding: (1) the role of disease-mediated natural
selection in amphibian communities, (2) the evolution of life history traits, and
(3) the population ecology of species distribution edges. My research follows an experimental
population biology approach, integrating laboratory, field, and molecular studies
in testing hypotheses related to mechanisms of amphibian population decline.
