Our lab is broadly interested in the origin and maintenance of plant diversity in deep and shallow evolutionary time. Anthropogenic climate change, phylogenomics, biome evolution, and plant-animal interactions are recent focal areas of our research. We are currently investigating phenological responses to climate change in the eastern United States by leveraging thousands of digital museum collections using crowdsourcing; applying genome-scale data to investigate molecular evolutionary phenomena, including whole genome duplications, deep coalescence, horizontal gene transfer, and hybridization; using biogeographic approaches to investigate the origins of biomes; and comparative and developmental methods to investigate plant-pollinator mutualisms. Student and postdoctoral research projects have employed multiple techniques spanning the fields of genomics, systematics, development, ecology, and bioinformatics. The taxa we investigate range from algae to angiosperms with a particular focus on Malpighiales.
