Research Areas

Current Project
Currently I am working on the 'Managing declining pine stands for the restoration of red-cockaded woodpecker habitat' project. Two main questions are: (1) Which loblolly pine stands on the landscape are most susceptible to decline?(2) Can individual tree mortality be predicted?
Research Interests
The central theme of my research addresses effects of disturbances on processes in forest ecosystems over various spatial and temporal scales. My current research interest is to evaluate and quantify the effects of disturbance on the ecological processes in forest ecosystems, and my specific questions are (1) how can ecologists provide sound information to the land managers and policy maker to establish sustainable ecosystem management, (2) how will urban landuse change over time and what will be the effect on the surrounding ecosystems, (3) how can the biogeochemical knowledge acquired from a stand level be extrapolated to the landscape level, and (4) will natural ecosystems with different ecosystem legacy respond the same to a disturbance.
