Research

My research broadly focuses on the evolution and systematics of reptiles and amphibians, primarily in the West Indies and Southeast Asia. I’m interested in using genome-scale data, along with morphological and biological data, to understand how biodiversity arises and is maintained across microevolutionary and macroevolutionary scales.

Research Foci:

Systematics and Taxonomy of Caribbean and Southeast Asian Amphibians and Reptiles

Genomics of Caribbean Iguanas
This is a collaborative project with Dr. R. Graham Reynolds (UNC Asheville) that uses novel genome-scale data to understand the phylogeny, historical biogeography, and species diversity primarily in the genus Cyclura— a remarkable yet critically threatened group of iguanas distributed throughout the Greater Antilles. Research derived from this project has already been published (Miller et al. 2019).

Understanding Cryptic Species Radiations
Species are the fundamental units which we derive our inferences of evolutionary dynamics, yet we have no singular criterion for how we define species! This conundrum is especially magnified in what we call “cryptic species”, taxa that show little to no morphological divergence yet considerable genetic divergence. Understanding how cryptic species arise is a particularly interesting facet of this fascinating phenomenon. Thus far, I have worked with colleagues at the Smithsonian Institution and the University of Oklahoma to demonstrate this concept empirically in reptiles from Myanmar– specifically skinks and pitvipers.
