Specific Research Interests
My research in plant systematics lab focuses on the systematics and evolution of land plants with three general objectives:
   1) to infer the phylogenetic relationships of plant groups and to use that pattern of evolutionary history to assess aspects of character evolution, biogeography, ecology, and evolutionary process;
   2) to investigate the delimitation of plant species and infraspecies, especially in evaluating rare/endangered taxa;
   3) to discover the plant species and community structure of regions in floristic studies.

Current Projects
My field work in Chile and Argentina was supported in part by the National Geographic Society. I and my colleagues are working on the phylogenetic relationships of the Amsinckiinae (Boraginaceae), which occur in both North America and South America (a few in Australia), and not in the intervening tropics, and are termed American Amphitropic Disjunct plants. See my web page on Some Plants of Chile/Algunas Plantas de Chile.
