played a major role in the burgeoning use of zebrafish as a model for revealing how brains produce behavior. His team was the first to apply many of the tools now in common use in such studies, including in vivo imaging of activity in groups of neurons in the brain and spinal cord of an intact vertebrate; using lasers to remove neurons in intact fish and test their roles in behavior; imaging (and inducing) regeneration in an intact vertebrate; and more. Over the last decade, Dr. Fetcho was an elected fellow of the American Association for the Advancement of Science, served as the Victor Hamburger Lecturer at Washington University, the Grass Foundation Forbes Lecturer at the Marine Biological Laboratory in Woods Hole, and participated on multiple NIH reviewpanels, including co-chair of the NIH BRAIN Initiative panel that awarded the first Team-Research BRAIN Circuit grants. Joseph Fetcho graduated from Lehigh University with a B.S. in biology in 1979, received a Ph.D. in biological sciences in 1985 from the University of Michigan and did postdoctoral work in neuroscience at the State University of New York at Buffalo. He was initially a faculty member at Stony Brook University and later joined the faculty at Cornell University in 2004 where he served as an associate chair of the Department of Neurobiology and Behavior from 2009-2017. Over the last 25 years, Dr. Fetcho’s laboratory has studied the zebrafish model to reveal principles of the development and functional organization of the nervous system that are likely to be shared by all
