Tina Ayers, Ph.D 
Director and Curator

Tina’s research interests are in the systematics of flowering plants, specifically neotropical Campanulaceae; she teaches introductory botany (BIO 284) plant identification courses (BIO 414, Native Plants; BIO 415 Plant Taxonomy; BIO 517 Agrostology) and upper division/graduate courses in evolutionary biology (BIO 435C), Biogeography (BIO 663), and Floristics (BIO 599).

Currently, Tina is completing a monograph of the genus Lysipomia (Campanulaceae), a genus of about 50 species endemic to the Andean alpine tundra. Additional projects include a phylogenetic analysis of Nemacladus, which is being done in collaboration with Dr. Nancy Morin; systematics of Cyphocarpus in collaboration with Kimberly Hansen, a former master's student; and systematics of Lobelia and Diastatea in Mexico and Central America, in collaboration with Elizabeth Johnson, a former master's student. All of these studies involve gathering molecular sequence data from chloroplast or nuclear genomes and collecting macro- and micromorphological data. Tina is also interested in rare plant conservation and florisitics, especially in the southwestern United States and northern Mexico and mentors students in these areas as well as plant systematics.

Greg Goodwin

Greg Goodwin, M.S. 
Associate Curator

Greg became a volunteer for the Deaver Herbarium after retiring from the U.S. Forest Service, where he worked for 28 years, including 21 years with the Coconino National Forest. Greg is in the herbarium a few mornings per week processing historical collections donated by the U.S. Forest Service or processing his own collections from travels throughout the West. Greg is also compiling a floristic inventory of the Cataract Canyon drainage. This effort includes surveying for rare plants.

Glenn Rink

Glenn Rink, M.S. 
Associate Curator

Without question, Glenn is out in the field collecting plants for various agencies or just for fun on most days. He is currently documenting flora in southern Colorado Plateau area, focusing especially on the Kaibab Plateau. Glenn is also currently collaborating with Max Licher on revisions of the Cyperaceae and Juncaceae for Arizona and New Mexico.

Randy Scott

Randy Scott, Ph.D. 
Associate Curator

Randy is currently working on a monograph of the genus Brickellia (Asteraceae), a genus of 90 to 100 species found primarily in the southwestern United States and Mexico. He also lends a hand wherever he is needed at the herbarium, including identifying many of the unknown Asteraceae the herbarium receives, filing newly mounted specimens, giving tours, and whatever else comes up.

John Spence

John Spence, Ph.D. 
Associate Curator

John Spence, who lives in Page, Arizona, is the botanist for Glen Canyon National Recreation Area. He regularly visits the Deaver Herbarium to work on specimens from around the world that have been loaned to the herbarium. John’s interests are wide ranging and include the biogeography and evolution of Colorado Plateau flora, especially endemic and rare species; vegetation ecology and classification; bryophyte and vascular plant systematics; bird inventory, monitoring, and ecology; and ecological effects of climate change.
