In our lab we work on the fascinating connections between molecular evolutionary processes and genotypic/phenotypic diversity. Our many research projects explore various aspects of molecular and genome evolution, phylogenetics, and phenotypic evolution of higher plants. We use a diverse set of technologies and approaches to explore the manner in which genomes change over evolutionary time, as well as the relationship between these events and morphological change. We have a particular interest in the mysterious and common phenomenon of genome doubling, or polyploidy, with a special focus on the cotton genus (Gossypium). Read more about
Polyploid speciation is exceptionally common in plants, often operating sympatrically to saltationally generate new lineages.
Comparative evolutionary genomics and domestication genomics are among the most active areas of research in the lab. Please check back here often for updates on our massive genomic resequencing effort, our comparative molecular evolutionary analyses, and our work on domestication genomics.
