My primary field of interest is developing quantitative decisision support tools to aid forest and natural resource management. I am particularly interested in building and testing mathematical models that can quantify and visualize the resource trade-offs and production possibilities between conflicting management objectives. I do research in the areas of (1) forest management planning, including spatially explicit harvest scheduling models and multiple-criteria forest planning; (2) operations research, including integer programming, multiple-criteria optimization, and multiple-criteria decision support systems; and (3) the economics of non-timber forest benefits.
