Thomas H. DeLuca holds a doctorate from Iowa State University, a master’s degree from Montana State University and a bachelor’s degree from the University of Wisconsin-Madison, all in soil science, and lived in both Sweden and the United Kingdom during his research career. Prior to joining OSU, he headed the University of Montana College of Forestry and Conservation for three years and spent five years as director and professor at the University of Washington’s School of Environmental and Forest Sciences. Before that he held research positions in Europe; at the Wilderness Society in Bozeman, Montana; at the University of Montana; and at Slippery Rock University in Slippery Rock, Pennsylvania.
