Research and Professional Interests:

One of the most exciting questions in biology is How do new species arise? This question has intrigued and fascinated biologists from Darwin to the present. The goal of my research program is to gain insight into the process of speciation in order to understand the origin of biodiversity. I employ an integrative approach to studying speciation, which involves several fields of biology, including behavioral ecology, phylogenetics, phylogeography, population genetics, genomics, and ecology. I use amphibians as model systems for studying this process, focusing primarily on North American and South American taxa.

Current projects include (1) studying speciation-in-action driven by reinforcement in contact zones of chorus frogs, (2) developing improved methods for phylogeography, (3) investigating the evolution of acoustic signals across frog clades, (4) employing genomic approaches to developing markers for amphibian genetics, and (5) implementing genomic tools for targeted phylogenomics in amphibians.
