RESEARCH
Molecular phylogenetics, population genetics, and comparative
genomics
My research examines historical patterns of diversification among genes, genomes, and organisms. Various research projects use molecular characters to understanding evolution at several levels of organization including molecular evolution at the genetic or genomic level, divergence of populations and species, and phylogenetic patterns among species and higher taxa. Taxonomically, I am primarily interested in North American freshwater fishes, however I am also involved in projects on several other animal groups. Another major focus is development of methodological/computational approaches for improving phylogenetic inference by extracting historical signal from background noise in DNA sequences.
Prospective graduate students may pursue a wide variety of research projects that use molecular approaches in evolutionary biology. Graduate students will be enrolled in degree programs in the Department of Zoology. Numerous projects are also available for undergraduate honors research or independent study. If you have any questions about the lab or our research, or to enquire about joining the lab, please give me a call or send an e-mail.
