Our studies of sharks and rays are largely focused on using phylogenetic methods to infer evolutionary history and the trajectory of character evolution, including aspects of molecular evolution. Current research includes a collaboration with biologists from across the globe to infer how Carcharodon carcharias (pictured) utilizes the oceans of the world.

Organisms endemic to desert springs provide a superb opportunity to investigate how isolation and small population size contribute to the genomic and phenotypic diversification. Additionally, the system I work on is the target of large-scale conservation efforts aimed at restoring hydrological conditions that promote native species.

Our work uses forensic analysis of historical samples collected in the middle to late 1800s as a means of estimating the native diversity and distribution of cutthroat trout in the southern Rocky Mountains. The information will be used for conservation efforts aimed at establishing native species in localities where they once flourished.

Our work on prairie dogs focuses on inferring the demography and relating demography to the prevalence and spread of blood-born diseases (Yersinia, Bartonella and Rickettsia) across various landscapes, especially landscapes subject to increasing urbanization.
