Systematics, biogeography, and patterns of evolution of various angiosperm groups, especially plant diversity of Pacific oceanic islands and the evening primrose family (Onagraceae). Morphological and molecular data are used to discover, describe, and interpret biological diversity, and create predictive classification systems, examine phylogenetic relationships and biogeographic patterns of lineages. Application of systematic and biogeographic information is used to address questions in population biology, conservation biology, and evolution.
