Thomas Quinn is a leading authority on the behavior, ecology, evolution, and conservation of salmon and trout. For over three decades, he has been one of the principal researchers for the UW Alaska Salmon Program, where his research has helped to reveal many of the patterns and processes in the behavior of salmonids. He has used a wide variety of laboratory, field, and analytical approaches to study migration, homing, reproduction, and habitat requirements, including work on all species, and in stream, lake and marine habitats. His work on bear predation has revealed the complex relationship between bears and salmon, including the role bears play in transferring salmon carcasses to stream edges, where they are consumed by a variety of organisms. In Washington, he has studied the re-colonization of rivers by salmon after dam removal or modification, interactions between wild and hatchery-produced fish, and the movements of salmon and trout in Puget Sound. He has received both the Distinguished Teaching Award and Distinguished Graduate Mentor Award from the University of Washington, the Excellence in Teaching Award from the American Fisheries Society, and is an elected Member of the Washington State Academy of Sciences.
