Steve Cadrin has been a stock assessment scientist for over 30 years, previously with the National Marine Fisheries Service’s Northeast Fisheries Science Center in Woods Hole, Massachusetts Marine Fisheries, and New York Department of Environmental Conservation.  His accomplishments include the advancement of stock assessment methods for a wide range of invertebrate and finfish species, fishery management advice for regional, national and international fisheries, and global leadership in evaluating geographic stock structure and modeling spatially complex populations.  He has chaired several regional, national and international working groups and committees and has convened workshops, symposia, and conferences for the International Council for the Exploration of the Seas, National Marine Fisheries Service, New England Fishery Management Council, American Fisheries Society and the Northeast Fish and Wildlife Conference. Steve received the American Fisheries Society’s Award for Outstanding Marine Fishery Biologist for sustained excellence in marine fishery biology, the University of Massachusetts Dartmouth’s 2021 Scholar of the Year Award, and the Joint Ocean Commission Initiative’s Excellence in Mentoring Inaugural Award. He is also Past President of the American Institute of Fisheries Research Biologists.  His teaching and research agendas focus on population modeling, stock identification, fisheries management, collaborative research with fishermen, and application of advanced technologies for fishery science.
