Phylogenetics and Comparative Analysis

My general interest in plant phylogenetics is the evolution of species traits and patterns of diversification. I have been investigating relationships within the diverse and taxonomically troublesome genus Carex with collaborators Anton Reznicek, Paul Rothrock, and Eric Roalson. The group exhibits a rapid radiation, extensive chromosomal diversity, and considerable convergence in morphological characters. We currently have funding to investigate the evolution of genome size and rearrangement in Carex subgenus Vignea. If you are interested in postdoctoral or graduate research under this project, please contact me. I am also broadening our studies in the black oak group (Quercus section Lobatae) to address phylogenetic questions. Past collaborations have included systematic studies in Croton (Euphorbiaceae), development of a Bayesian method for phylogenetic analysis of amplified fragment length polymorphism (AFLP) data, and evaluation of methods of testing for phylogenetic incongruence.
