Interests
My general research interests include the evolution, ecology, taxonomy, morphology and conservation of Neotropical diversity, with emphasis on amphibians and reptiles. In a collaborative effort with colleagues and students, we study the mechanisms that promote speciation in the Andes, Amazon basin, and the Galapagos Islands. We are also interested in the impact that introduced species and diseases have on the diversity and phenotype of native species.
