I am interested broadly in patterns of plant diversification and pursue research in phylogenetic systematics, species delimitation, comparative morphology and conservation genetics. Comparisons between levels of morphological and molecular divergence and phylogeographic patterns of divergence are growing areas of activity in my lab. Outreach includes general information on taxonomic groups such as for the Tree of Life Project and floristic treatments for the Jepson Manual: Flowering Plants of California and the Flora of North America project.
