Research Interests

I am interested in the evolutionary and historical processes that generate species diversity, and how species come together to form ecological communities. Recently, I have begin to study convervation and the demise of biodiversity. My research seeks first to elucidate the mechanisms that promote population divergence, typically regarded as the first step towards speciation, including demographic, genetic and behavioral mechanisms as well as environmental factors. Second, it seeks to understand the relative roles of adaptation and historical contingency in producing the spatially heterogeneous patterns of species richness. Third, I investigating current extinction trends in Central American amphibians and infer historical extincion patterns, as well.

Revealing the origins and demise of biodiversity requires integrating across disciplines in evolutionary biology and across multiple levels of biological organization. My research uses population genetics theory and tools to investigate genealogical processes responsible for the conversion of within population polymorphism into between population divergence. How these demographic processes then lead to the spatial distribution of independent evolutionary lineages is evaluated through phylogeographic analyses. Environmental change we predict should leave a consistent imprint on the spatial distribution of genealogical lineages across those co-distributed species with similar ecological requirements. Comparative phylogeographic approaches can therefore be used to tease apart the relative contributions of historical factors versus species-specific evolutionary processes in the assembly of local communities of organisms.

The core of this integrative research program is evolutionary genetics, which provides a rich, unified body of theory that supports studies from historical demography to molecular phylogenetics at deep temporal scales. Our ability to make historical inferences from molecular data depends on our understanding of evolutionary genetic processes, principally mutation, genetic drift and natural selection. Therefore, I am also interested in the study of rates of molecular evolution as well as the application of coalescent theory to the development of parametric tests of spatial and historical demographic models of arbitrary complexity.

I engage in collaborative investigations of Neotropical amphibian systematics and taxonomy. I am helping to lead a campaign to develop a reference database of amphibians from Panama and other Neotropical countries, in association with with the Smithsonian Institution’s Laboratory of Analytical Biology and the Consortium for the Barcode of Life.
