I am an Associate Professor at Florida International University. My 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 work primarily in the Andes and the Amazon. I collaborate with colleagues in 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, 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.
