My current research interests are the systematics and conservation of Neotropical amphibians and reptiles, and the ecological dimensions of biodiversity. For the first line of research, I have worked primarily in Peru, where I lead several research projects in the Andes and the Amazon, and where I participate in rapid field inventories. I collaborate with colleagues in natural history museums and other research institutions in describing new species and developing phylogenies of frogs from the mega-diverse eastern slopes of the Andes. I am interested in using phylogenies as a road map to compare and contrast physiological traits among species, specifically traits related to thermal physiology. As part of these investigations, my collaborators and I are studying thermal preferences, tolerance to heat, and the influence of temperature on physiological functions, in order to understand how climate warming will affect these animals. Finally, a major theme of my current research is exploring the effects of fungal disease on the ecology of amphibians, a group that is experiencing staggering biodiversity losses worldwide. After documenting the collapse of a species-rich amphibian assemblage, I am interested in developing strategies to mitigate the impact of the fungal disease chytridiomycosis on surviving species.
