Plant Biodiversity and Conservation Biology

My research focuses on the evolution of plant-insect interactions, specifically interactions between bees and their pollen and nectar host plants. I integrate both the botanical and entomological aspects of these interactions; I also address conservation implications of these interactions. My current research projects include using molecular phylogenetic approaches to examine 1) the evolution of pollen host choice in specialist bees and 2) the early evolutionary history of bee/angiosperm relationships. Additionally, I am examining the breeding systems, correlates of reproductive success, pollination ecology, and population genetic structure of several species of rare plants.
