Erin Tripp (Curator)
Erin Tripp has served as Curator of the COLO Herbarium since 2013. She studies systematics, evolution, and floristics of the large (>4,000 species), pantropical plant family Acanthaceae. Additionally, Erin is interested in the biodiversity, evolution, and conservation of the North American lichen biota.

Tim Hogan (Collection Manager)
Tim Hogan has served as collection manager of the Herbarium since 1991. Along with his curatorial responsibilities in the herbarium, he has pursued floristic studies throughout Colorado. Areas collected and reported on include the Sangre de Cristo Mts., the Needle Mts. in the San Juans, the Eagles Nest Wilderness in central Colorado, Boulder Mt. Parks and Open Space, and Black Canyon of the Gunnison National Park.

Dina Clark (Collection Manager)
Dina is responsible for the daily care and curation of the collection. She is interested in floristics, particularly of the High Plains, and has been studying the flora of Colorado's eastern plains for 20 years. She has a great appreciation for the vital role that herbaria and natural history collections as a whole play in our understanding of biological diversity.

Hazel Schmoll Research Fellowship in Colorado Botany
The Schmoll Research Fellowship was established in memory of Dr. Hazel Schmoll, an alumna of CU-Boulder and the first woman to receive a Ph.D. in Botany from the University of Chicago in 1935. The fellowship aims to continue her work of research and education in Colorado botany, with an emphasis on field botany, including systematics and ecology, of Colorado plants. It is open to students, faculty, and staff of the University of Colorado, with awards of up to $500.
