We are working on the systematics, biogeography, and evolution of plants. Long-standing interests are plant/animal interactions and the evolution of plant sexual systems and sex chromosomes. Biogeographic work has focused on Cucurbitaceae, Melastomataceae, Chloranthaceae, Araceae, and families in the order Laurales, namely Calycanthaceae, Atherospermataceae, Hernandiaceae, Lauraceae, Monimiaceae, and Siparunaceae *see online Flora of Ecuador. In much of this work, molecular clocks and their calibration with fossils play a large role.
