Personal Summary:

Woodam Chung is an Assistant Professor of Forest Operations in the Department of Forest Management at The University of Montana. He was born in Seoul, South Korea, and received his B.S. and M.S. in Forestry from Seoul National University, Korea. After he spent two years in Indonesia working in Forestry and Agriculture as an international volunteer, he came to Oregon and received his Ph.D. in Forest Engineering from Oregon State University. He teaches courses and conducts research in the fields of GIS, forest roads, harvesting systems, and combinatorial optimization techniques for forest planning. He has been active in developing decision-support systems for forest transportation planning, forest operations design, and spatially-constrained harvest scheduling. He played a major role in the development of NETWORK2000, which is designed for optimizing fixed and variable cost transportation problems. The program has been used by the USDA Forest Service, state agencies, industry, and researchers in the United States and other countries including Chile and South Africa.
