Graduate Interest Group(s): SUSTAINABLE RESOURCE MANAGEMENT; WILDLIFE SCIENCES

B.S., Forest Engineering, University of Forestry and Wood Sciences, Sopron, Hungary, 1994
M.S., Agriculture, Shinshu University, Nagano, Japan, 2002
Ph.D., Forest Resources and Operations Research, Pennsylvania State University, 2005

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.
