Positions

Overview

  • Professor Fredriksson joined the School of Marine Science and Ocean Engineering and the faculty of Mechanical Engineering at the University of New Hampshire (UNH) in August 2022. He is also the Director of the Center for Sustainable Seafood Systems. Dr. Fredriksson brings over two decades of experience developing ocean engineering methodologies for the farming of finfish, shellfish and macroalgae, with the goal of supporting seafood security for both the United States and abroad. His underlying passion is to grow new sustainable production methods and educational programs that will enhance both local maritime communities and the ocean environment. Professor Fredriksson has been the Principal Investigator for numerous research efforts, with projects most recently funded by the Department of Energy, World Wildlife Fund, National Oceanic and Atmospheric Administration and Atlantic States Marine Fisheries Commission.
