My research has focused on two areas in evolutionary genetics: 1. Reconstructing the history of populations representing different stages of speciation and 2. Using DNA sequence data in combination with other data to provide a robust historical framework for examining evolutionary processes. In my research, I have tried to apply innovative tests of phylogenetic patterns to molecular data in order to make reliable inferences of history. I have studied the evolutionary histories of both salamanders and lizards. Currently, my research has focused on the evolution of geckos at both broad and shallow time scales. Matt Heinicke, Sayantan Biswas, Tony Gamble, Eli Greenbaum, Aaron Bauer and I have all contributed to this project. Aaron Bauer, Sarah Smith, Ross Sadlier of the Australian Musuem and I have been investigating the phylogenetic relationships of the entire herpetofuana of New Caledonia. My postdoctoral research involved documenting and reconstructing parallel adaptive radiations in Caribbean anoline lizards using DNA sequences as well as morphological and ecological measures of habitat use.
