Graham Young is a biologist who studies the roles that hormones play in the development and reproduction of fishes. After a career that has taken him from England to Japan to New Zealand, he now works primarily on salmon in the Pacific Northwest. In addition to his work on the general role of hormones, he investigates how environmental contaminants can disrupt signaling by hormones, and what effects that can have on fish as they develop and reproduce. He also does research on the culture of finfish, and is the Executive Director of the Western Regional Aquaculture Center (USDA-NIFA). In that capacity, his program funds multi-state research into sustainable aquaculture practices throughout the western U.S.
