Robert Wagner, head and professor, comes to Purdue from the University of Maine, where he was the Henry W. Saunders Distinguished Professor in Forestry and the Director of the Center for Research on Sustainable Forests and Cooperative Forestry Research. He received his bachelor's degree in forest management from Utah State University, his master’s in forest ecology/silviculture from the University of Washington, and his PhD in silviculture/vegetation management from Oregon State University. He served as a program leader and senior scientist at the Ontario Forest Research Institute in Ontario Canada before joining the faculty in the School of Forest Resources at the University of Maine. At Maine he served as Director of the Cooperative Forestry Research Unit, Associate Director of the Forest Bioproducts Research Institute, and Director of the School of Forest Resources prior to his appointment as Distinguished Professor and Director of the Centers.

Dr. Wagner's research career has focused on improving the success of forest regeneration following harvesting, as well as improving the productivity, composition, and quality of young stands. His work in this field has focused on forest ecosystems in the Pacific Northwest, Canada, and New England. Dr. Wagner’s recent efforts have focused on understanding patterns of natural regeneration following partial harvesting of forest stands, the economics and stand dynamics associated with thinning spruce-fir stands, how to improve the quality of hardwood regeneration in diseased beech-dominated stands, and the effects of silvicultural intensity and compositional objectives on stand productivity and dynamics.
