I joined the faculty of Louisiana State University in August 2011. An empirical biologist at heart, I develop, test, and apply statistical methods for inferring and using phylogenies. I used these methods to address important biological questions including identification of the earliest diverging lineage of extant ants, the use of phylogenies as forensic tools in cases of HIV transmission, the phylogenetic placement of turtles & relationships among major groups of tetrapods, and the characterization of broad, genome-wide patterns of molecular evolution.
Much of my work currently focuses on the development of (primarily Bayesian) statistical approaches for inferring evolutionary history from genomic data. I, and other members of the lab, also contribute to the development of open source software for conducting phylogenetic studies. Lately, we’ve been working a lot on the RevBayes and TreeScaper software packages.
