Brian is a fisheries biologist specializing in the impacts of human energy development on fishes and has conducted extensive research in hydropower-dominated basins in the U.S. and abroad. He is inspired by innovation and spends much of his time at PNNL developing new research areas toward improving our Earth-energy systems.  Of special interest to Brian is understanding the interactions between renewable energy (in particular, waterpower) and how new technologies can be used to reduce the human impacts of energy generation on rivers and other aquatic systems.  Currently at PNNL, he leads the development of new research areas including development and application of technologies to reintroduce migratory fish to areas where they have been blocked due to hydropower dams, promoting the development of innovative fish passage technologies to reduce the cost and improve the safety and efficacy of fish migratory connectivity, and building teams to improve cybersecurity protection of hydropower facilities.
