     Ph.D., Biology, Washington University, St. Louis, MO, December 1981 (Advisor: Peter H. Raven; Thesis title: A systematic and evolutionary study of the Oenothera caespitosa species group, Onagraceae) M.S., Biology, University of New Mexico, Albuquerque, NM, August 1977 (Advisor: William Martin; Thesis title: Floristic affinities of the Animas Mountains, southwestern New Mexico) B.S., Biology, University of New Mexico, Albuquerque, NM, 1973

Research Interests
     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.
