John Horne is a fisheries biologist who uses acoustical techniques to understand the spatial structure and abundance of aquatic organisms, which in turn is used to inform resource management. He uses ecological theory to predict the relative importance of biological and physical processes on the distribution of fish, and his research scales from the individual up to entire ecosystems. He is also associated with the Quantitative Ecology and Resource Management (QERM) program and the Center for Quantitative Science (QSCI). In addition to his work for UW he collaborates with scientists at the NOAA Alaska Fisheries Science Center. He has won the Medwin Prize in Acoustical Oceanography from the Acoustical Society of America.
