I am a botanist at College of the Atlantic (COA) in Bar Harbor, Maine.  My primary research interest is in understanding the role extreme edaphic (soil) conditions play in generating and maintaining plant diversity. I teach a range of botany courses, including Edible Botany, Ethnobotany, Trees and Shrubs of Mount Desert Island, Plant Taxonomy, and Plant Evolutionary Processes, and other biology courses such as Form and Function and Biogeography.
