My interests are in plant systematics,
biogeography, and floristics. I teach courses in all of these topics, as well,
although only plant systematics is offered at the undergraduate level.
Currently, I am completing a monograph of
the genus Lysipomia (Campanulaceae), a genus of about 40 species endemic to the
Andean alpine tundra.
Additional projects include a molecular
phylogenetic analysis of Nemacladus, in collaboration with Dr. Nancy Morin,
systematics of Cyphocarpus, and systematics of Lobelia in Mexico and Central
All of these studies involve gathering
molecular sequence data from chloroplast or nuclear genomes, as well as
collecting macro- and micromorphological data. I am also interested in
florisitics, especially in the southwestern U.S. and northern Mexico.
My recent graduate students have
completed florisitic inventories of two areas in northern Arizona/southern Utah
funded by the National Park Service. For more information on these studies,
visit the Deaver Herbarium site.
