I am Professor Emeritus at the Flathead Lake Biological Station of the University of Montana, where I have worked since 1972. I was the Director and Bierman Professor of Ecology (1980-2016). My academic degrees are: B.S. in Fisheries Science at Colorado State University (1969); M.S. in Limnology at Colorado State University (1971); Ph.D. in River Ecology at University of Utah (1975). I was Assistant and Associate Professor of Biology at University of North Texas (1974-80). I have trained and graduated 14 Ph.D. and 28 M.S. students and published over 220 scientific papers and books on aquatic ecosystem processes, including influences of human activities.
During my 50-year career, my research has been supported by over $60M in competitive research grants from the U.S. National Science Foundation, the Gordon and Betty Moore Foundation (Palo Alto, CA), the McKnight Foundation (Minneapolis, MN) and many other funders. I was elected Fellow of the American Association for Advancement of Science (2000). I received the Award of Excellence of the Society for Freshwater Science in 2004 and in 2011, I received the Lifetime Achievement Award of the International Society for River Science. My current work focuses on the ecology and conservation of Pacific Rim salmon rivers. I have served on many scientific review boards and currently serve as trustee of Skeena Wild Conservation Trust (Terrace, BC) and the board of the Wild Fish Conservancy (Duvall, WA). I currently reside on the Twisp River, Washington, with my wife and professional colleague, Dr. Bonnie K. Ellis.
