Research/teaching interests

  • plant systematics
  • biogeography
  • floristics

Academic highlights

  • PhD: University of Texas, Austin, Botany, 1986
  • BA: University of Texas, Austin, Botany, 1979

I teach introductory botany (BIO 284), three different plant ID courses (BIO 414, 415, 517), evolutionary biology (BIO 435C), and biogeography (BIO663).

As a plant systematist I describe new species, revise taxonomy, and study evolution. Most of my research focuses on neotropical plants in one family, the Campanulaceae. My recent graduate students are describing new species of plants in Arizona and Mexico, or completing systematic studies, population genetics studies of rare plants, or floristic inventories of areas in northern Arizona/southern Utah. For more information on these studies, visit the Deaver Herbarium site.
