Systematics), Michigan State University, Lansing, 1993.
My long-term research interests include the study of evolutionary processes within plant populations, particularly slipper orchids, and the analysis of genetic differences among populations. I am especially interested in how the demographic, life history, and ecological characteristics of orchids influence their patterns of intra- and interpopulational genetic variation and contribute to speciation patterns.
I have also recently initiated several other projects with my students. These include a floristic analysis of Totuskey Creek Watershed on the Northern Neck Peninsula, analyses of lichen diversity in the Williamsburg area, and the conservation biology of American ginseng. The projects involving American ginseng include the influence of breeding system on fitness, documentation of potential loss of populations throughout history, and conservation genetics
