Biography

Dr. Geist joined Battelle in 1991. He is currently the Technical Group Manager for the Ecology Group within the Earth Systems Science Division. In his role as Technical Group Manager, he supervises approximately 50 aquatic and terrestrial biologists and technicians that study natural environments around the world. Since joining Battelle, Dr. Geist has studied how energy development projects affect the physiology, behavior and ecology of fisheries resources in the Pacific Northwest. He is a recognized expert on how hydroelectric dams affect the migration patterns and energy use of adult salmonids; he has researched the impacts of hydroelectric development on the salmonid spawning and incubation habitat, including the effects that dams have on the temperature and dissolved oxygen of the incubation environment where fishes develop; and he continues to be lead scientist and project manager for several projects addressing environmental monitoring and technology application in aquatic environments.
