My lab is very broadly interested in the evolution of floral morphology. We use molecular, morphological, and phylogenetic approaches to study how flowers have changed over the course of evolutionary time. Research projects in the lab cover a diverse set of topics, including gene lineage evolution and the effects of gene duplication, the morphological diversification of floral parts such as petals and fruits, and the evolutionary and ecological significance of pollinator interactions. Within this context, one of our major focus areas is the development of Aquilegia (columbine) as a new system for studying evolutionary and ecological questions, but we also work on other diverse lineages, including Loasaceae and Tropaeolum.
