Our research is centered on the processes and patterns involved in the evolution and diversification of plants, especially the monocots. We use a phylogenetic framework to test hypotheses of morphological evolution and to analyze temporal and spatial patterns of plant speciation and diversification. The use of systematics in comparative biology is emphasized. Areas of focus are on the evolution of development, comparative genomics and the genetics of interspecies interactions.
- Phylogenetics, species-level systematics, and evolution of Monocot lineages, including the tropical gingers (Zingiberales), Nolina (Ruscaceae) and California Allium.
- Floral development and evolution of the Zingiberales.
- Evolution of plant traits, including pollination syndromes, thermogenesis and wood anatomy associated with the liana habit.
- Population genetics and phylogeography of mexican and californian plant lineages (Nolina, Calochortus).
- Development of Comparative Analysis Software and Visualization (ArborWorkflows.com).
