I am a botanist and ethnobotanist, mostly focused on the Appalachian region of the United States. Beginning in 2019–2020, I will be involved in ethnobotanical research in Madagascar with colleagues in Anthropology.
In addition to teaching for Ecosystem Science and Management, I have a research and outreach program that is focused on developing sustainable forest-based stewardship and cropping systems for Appalachian specialty forest products (i.e., non-timber forest products) including American ginseng (Panax quinquefolius), goldenseal (Hydrastis canadensis), and ramps (Allium tricoccum). My students and I conduct interdisciplinary research on these products on questions relating to botany, ethnobotany, ecology, phytochemistry, and horticulture.
Courses that I Teach at Penn State
- FOR 203 Field Dendrology (w/ Margot Kaye)
- FOR 303 Herbaceous Forest Plant Identification, Ecology and Ethnobotany
- FOR 403 Invasive Forest Plant Identification, Ecology and Management
- FOR 418 Agroforestry: Science, Design and Practice (in even years)
