I am a herpetologist who uses a multidimensional approach to understand how species evolve across space and time using integrative methods that bridge the fields of phylogenetics, biogeography, and landscape-population-conservation genetics. By elucidating the link between micro-evolutionary processes and macro-evolutionary patterns, I hope to understand the mechanisms underlying the generation and distribution of biodiversity. I am particularly interested in understanding how gene flow affects tree inference, species estimation, and the evolution of phenotypic traits.
