BIO

I spent my early years in the foothills of the Appalachian mountains in eastern Tennessee, and developed a passion for botany at a young age. As an undergraduate I took a lot of field ecology classes, worked for the arboretum, and interned with the Smithsonian Environmental Research Center studying native orchids and their mycorrhizal fungi. After graduation, I spent a year researching the pollination ecology of purple cone flower in western Minnesota, and two years doing plant identification, data management, and statistics for ecologists at the University of Minnesota. I moved to Wisconsin in 2007 to study botany at UW-Madison in the Givnish lab, specializing in orchid systematics and ecology. Seven years (including over a year of field work abroad) and two children later, I finally had my doctorate. After a short stint in Ohio, I joined the biology department at UW-Stevens Point where I teach several botany classes including Vascular Plant Taxonomy and Agrostology and serve as director of the UWSP herbarium and the UWSP tropical conservatory.
