Biography
Dr. Guy received his Ph.D. from South Dakota State University in Fisheries Science before joining the Unit program in 1994. He conducts research within the broad context of fish ecology and fisheries management. A consistent research theme of his has been on native fish assemblage restoration, a prominent ecological and societal issue within the USA and globally. Within that theme, his research has two areas of emphasis—conservation of large-river fishes and suppression of invasive species (for conservation of native fishes). These areas encompass a broad diversity in ecosystem types and fish assemblages—from large warm-water rivers to alpine lakes. Given the mission of the Cooperative Research Units program, he willingly assists natural resource agencies with their research needs. As a faculty member at Montana State University, he serves on university committees, teaches graduate courses (Fisheries Science and Communications in Ecological Sciences) and seminars, and guest lectures in a variety of graduate and undergraduate courses.
