Current Research

I pursue lines of research in forest modeling and forest sampling. Under the modeling line, I am currently investigating how patterns of co-allocation of carbon and nitrogen within trees affect the net primary productivity of forest stands. My goal is to gain a fundamental understanding of the biological processes, environmental contraints, and resource limitations that govern forest stand dynamics. Under the sampling line, I am investigating Monte Carlo approaches to sampling the carbon components of the forest with randomly placed lines and points. The 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. Research in both lines is conducted with the aid of colleagues.

Research Interests

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

Why This Research is Important

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