Research Interests

I study biogeography, systematics, and conservation biology of amphibians and reptiles.  My primary interests are in the processes involved with speciation, including vicariance, dispersal, and local adaptation to environmental regimes.  I use mitochondrial and nuclear sequence data to track the evolutionary histories within species complexes in association with geography and to test phylogenetic hypotheses of more distantly related taxa at the specific, generic, and family levels.  I also use morphological data from museum specimens to address systematics and taxonomy, and physical trends with environmental conditions.  My current research is focused on co-distributed taxa in the deserts of western North America, including those affected by plate-tectonic activities associated with the formation of the Baja California Peninsula.  My postdoctoral position at the Smithsonian Institution involves a morphological revision of Nightsnakes of the genus Hypsiglena.
