My research focuses on the effect of environmental gradients on the molecular evolution of neotropical montane frogs. At a broad scale, I employ highly polymorphic molecular data to determine how latitude and climatic zonation affects dispersal in different species in the Andes. At a finer scale, I use DNA sequence data to determine the effect of elevation on the population-level molecular diversity of frogs.

In addition, I use phylogenetic approaches to understand the mechanisms that promote and maintain the tremendous history of anuran speciation along the Andes.
