Welcome to the Hein Group based at the University of California Santa Cruz’ Institute of Marine Sciences and NOAA’s Southwest Fisheries Science Center. We study how organisms acquire, share, process, and respond to information. We use experiments, mathematics, and computational models to understand the rules organisms use to make decisions, how these decisions influence the rates of ecological interactions and the dynamics of ecosystems, and how ecosystem policy can account for these processes. See our research pages for more information.
