Dr. John Stieglitz is a Research Associate Professor in the Department of Marine Biology and Ecology at the University of Miami’s Rosenstiel School of Marine, Atmospheric, and Earth Science and serves as the University’s Director of Sustainable Seafood Research and Development, as well as the Associate Director of the Cooperative Institute for Marine & Atmospheric Studies (CIMAS). His research advances sustainable aquaculture and fisheries through applied science that addresses production challenges, resource efficiency, and environmental resilience. A portion of his work examines the physiological responses of marine fish to environmental conditions, generating insights that improve aquaculture systems and inform fisheries management. His research aligns with NOAA Fisheries priorities by assessing how environmental changes impact commercially important species, building resilience in fisheries and aquaculture, and supporting restoration of critical habitats. He also examines seafood market development and sustainability within the seafood business sector, providing insights that strengthen economic opportunities for U.S. aquaculture and fisheries. In addition to research, Dr. Stieglitz teaches graduate and undergraduate aquaculture courses and collaborates with federal scientists, industry partners, and Sea Grant programs to develop best practices, expand seafood sustainability, and foster resilient domestic seafood systems.
