Permanent Staff:
Shelley McMahon - Herbarium Director
My research in plant systematics has focused on papilionoid legumes,
particularly in the Amorpheae, a group of c. 240 New World arid/semi-arid
species, which includes Dalea,
Marina, Psorothamnus,
and Amorpha. My interests include the evolution
of variation in floral morphology among lineages, their developmental morphology,
and who is related to whom. I am also interested in general systematics
of legumes and angiosperms, phylogenetic methodology, and large-scale phylogenetics
and tree-of-life efforts.

Philip D. Jenkins - Curatorial Specialist
At this point in my life I fear a comprehensive record of my educational
and professional past may be too lengthy to hold anyone's attention,
so I am presenting a somewhat eclectic summary of a few of the major points.

Gene Hall - Collections Manager
My primary interests are in the management of natural history collections, which allow us to preserve and
document the history of life on Earth, and research utilizing systematics, morphology and biogeography to
better understand our planet’s biodiversity. Examples include studies on the evolutionary relationships
of the beetle groups Ptiliidae, Hydroscaphidae, Sphaeriusidae and Limnichidae, and analysis of fossil
insects from pack rat middens of the Sonoran Desert. My research also focuses on botanical and
mycological systematics, including mosses of the southwest and fungus-beetle interactions.

Brad Boyle - Database Manager and Webmaster
I am interested in the development of informatics tools for the management and exchange of biodiversity
data, in particular herbarium collections and vegetation inventories. As demonstrated by some
recent publications, such collaborative
"mega datasets" are opening up exciting new avenues of research into plant diversity,
distribution and function.
