Research Interests:

My primary field of interest is developing quantitative decision 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 following thematic areas:

Forest management planning: spatially explicit harvest scheduling models, multiple-criteria forest planning.
Operations research: integer programming, multiple-criteria optimization, multiple-criteria decision support systems.
The economics of non-timber forest benefits.
