..........Research Interests:
I have broad research interests spanning important areas of plant ecology including tropical forest/biodiversity conservation, forest structure and human disturbances, exotic plant invasions, phytoremediation and dendrochronology. However, my current research focuses on the effects of prescribed fire and thinning treatments on tree growth and productivity in the mixed oak forest of the Central Appalachians. Fuel reduction treatments (FRTs) have received widespread application across the United States within the last two decades due to the need to mitigate wildfire effects and to restore regional forests to historical structure and function. In the mixed-oak forests of the eastern US, these management strategies are increasingly used to alter stand structure and promote oak regeneration. However, despite evidence suggesting the effectiveness of FRTs in achieving sustainable forestry, their effects on residual tree growth and productivity remain uncertain, particularly over the long-term. Additionally, less is known about the factors that influence the growth responses of these residuals trees to the restoration treatment methods.

Specifically, my study involves the application of dendrochronological, stable isotope, GIS and statistical modeling techniques to understand the long-term responses of mixed oak forests to FRTs and the biophysical factors that mediate such responses. The outcome of the study will have important implications for carbon sequestration, and forest management in the mixed oak forests of the Central Appalachians. It will provide new insights into the inherent tradeoffs in prescribed fire and thinning applications. Information gleaned from this study may also be useful for refining the prescribed fire and thinning management practices.
