Digitizing “endless forms”: Facilitating Research on Imperiled Plants with Extreme Morphologies (NSF TCN)

Profile

As Assistant Curator to the Herbarium, I serve two complementary roles: 1) Herbarium management and curation, and 2) Conduct original systematic research focusing on the megadiverse orchid family.

My duties as an herbarium manager include curation of the collections to reflect advances in systematic understanding, facilitate the use of the Herbarium, giving tours of the herbarium to a vast number of different groups, and grant writing to support digitization and curatorial efforts.

My research interests focus on the Orchidaceae: their evolution, relationships, morphology, taxonomy, and biogeography. My research incorporates field, molecular, and herbarium approaches to understand speciation and biodiversity, test patterns of apparent hybridization, clarify biogeographic history, and identify the conservation needs of New World Orchidaceae. Current genera of focus include Spiranthes (ca. 35 spp.), Pelexia (ca. 65 spp.), Cyclopogon (ca. 70 spp.), Platanthera (ca. 200 spp.), Microchilus (ca. 145 spp.), and Lepanthes (ca. 1000 spp.), and subtribe Goodyerinae (ca. 710 spp.).

Field research and collecting has covered much of eastern North America. I have a particular interest in Florida and the Atlantic Coastal Plain, Mexico, the Caribbean, and the Ouachita Mountains of Arkansas. I also eagerly collaborate with citizen scientists in the finding and monitoring of orchid populations, and the gathering of material.
