Current research addresses the patterns and controls of nitrogen (N) cycling dynamics in forest ecosystems with a primary focus on: i.) the role of fine roots in the N cycle, and ii.) the effects of prescribed burning on the loss, retention, and replacement of N in forest ecosystems. The primary goal of this research program is to gain an improved, mechanistic understanding of N cycling dynamics and controls on forest productivity which is critical to more accurately assess and predict the impact of management regimes (e.g., prescribed burning, site preparation, and harvesting) and anthropogenic disturbances (e.g., global warming, acid rain, and stratospheric ozone depletion) on the composition, structure, and function of forest ecosystems.
