Deciphering how flowering plant species arise and maintain themselves as unique identities, even among their close relatives, intrigues me and provides my primary research focus. Much of my work centers on native, North American orchid species, documenting population-level genetic variation, demography, and understanding the roles of various agents of natural selection on the reproductive success of individual plants and the longevity of populations in which they are included. Because this work is wide-ranging both intellectually and geographically, field and laboratory investigations inform these studies. Mathematical modeling of populations, qualitative and quantitative chemical characterization of floral fragrance variations, documenting floral visitors and pollinators’ effectiveness, and other techniques enable me to develop a fuller picture of what it means to be a flowering plant species.
I also contribute to documenting the plant diversity of the eastern United States by investigating plant communities both from an ecological and a floristic perspective and curating the Ramsey-Freer Herbarium at University of Lynchburg.
