I work on several interrelated questions that are centered around an interest in systematic biology. For example, how much do we know about the topology of the tree of life and how quickly are we learning? What, and how much, data are necessary to reliably infer species level phylogenies, particularly in the face of gene tree incongruence and ongoing gene flow? What are our prospects for collecting these data for non-model organisms? How does our knowledge of variation in threatened or endangered organisms inform our conservation goals and priorities?
Reprints of my papers are available on the Publications page and further information about some ongoing projects are available on the Projects page.
