Our research focuses on plant population dynamics and the processes that determine the composition and structure of plant communities over time and across landscapes. We are specifically interested in the role of clonal growth as a mechanism for population persistence in plant communities. 


We also study land-use history and exotic species introductions as drivers of long-term change in forest communities.  Much of our research is conducted within ecosystems of the southern U.S., concentrated on the southern Cumberland Plateau and on the coastal barrier islands.

The Sewanee Herbarium serves as a resource center for plant biodiversity on the Cumberland Plateau.
