Organismic and Evolutionary Biology
Evolution of genetic mechanisms controlling floral development; effects of gene duplication on the rates and patterns of both sequence and functional divergence. The focus of my lab can be broadly described as plant evolutionary developmental genetics, but our work touches on many fields, from systematics to genomics. In general, we are interested in the genetic basis of evolutionary change, particularly in relation to flower development.
Currently, much of our work is concentrated on the development of Aquilegia (columbine) as a model system for the study of evolutionary and ecological questions. We are particularly interested in the genetic basis for the evolution of the novel staminodia and petal spurs that characterize Aquilegia flowers. In addition, we are investigating the control of flowering time. See our lab website for information on other projects.
