Current Research:

I am studying the population dynamics, breeding system, habitat requirements of, and fire effects on rare plants in longleaf pine communities.Specifically, I am working on Macbridea alba, Harperocallis flava, Scutellaria floridana, and Echinacea laevigata (not longleaf systems).I am also working in the fall-line sandhills of South Carolina to develop strategies for restoring structure and composition in the ground layer vegetation of altered longleaf pine communities.Sandhills work includes evaluating the effects and interactions of mechanical treatments and prescribed fire on midstory reduction, and describing life histories and establishment requirements for common sandhills herbs.I am working with others to develop a monitoring strategy for Allium tricoccum (ramps) and to model population processes of this species in the Southern Appalachians.

Collaborative Research:

I am interested in collaborating on studies of the genetics and pollinationsystems of rare plant species.Also, I would like to collaborate in describing how below ground processes structure longleaf pine forests, and in modeling fire behavior and effects at landscape scales.Finally, I would like to collaborate in developing management strategies for harvested perennial herbs.
