Current Research

For the past 20 years, I have pursued lines of research in forest modeling and forest sampling. Under the first line, I am currently investigating, with colleagues, how to best model the co-allocation of carbon and nitrogen its effect on the net primary productivity of forest ecosystems. I am also pursuing analogous modeling research at the level of the individual tree, with the aim of determining how this co-allocation affects the growth rate of a tree and tree's interactions with its neighbors. The goal is to gain a fundamental understanding of the processes and resource limitations that govern forest stand dynamics. Under the sampling line of research, I am investigating Monte Carlo approaches to sampling the carbon components of the forest with randomly placed lines and points. This sampling research is also conducted with the aid of colleagues. Our objective is the advancement of sampling strategies that not only provide accurate and unbiased estimates of carbon stocks and their rates of change, but also are easy to use in the field.

Why is This Important

Our ability to answer pressing questions about the cycling of carbon through forests suffers from a lack of applicable theory, models, and methodology.

Future Research

The two lines of research will evolve with incremental advances and, with luck, the occasional quantum leap.
