- M.S. in Forest Biology from the University of Georgia.
- B.S. in Biology from Mercer University.
Research Interests
Current research addresses the patterns and controls of nitrogen (N) cycling dynamics in pine forests with a primary focus on the effects of prescribed burning on the loss, retention, and replacement of N in these ecosystems. The ultimate goal of this research program is to provide critical information for the development of more ecologically sound burning regimes for the long-term sustainable management of fire-maintained forest ecosystems in the southeastern United States.
