Johanna has 25 years of experience transforming natural systems to sustainable management. Collaborating with stakeholders and policy makers to find and leverage results is one of her many strong suits. In her current role, she is leading our program development for our fisheries work in Japan. She also leads a team of experts in strategic development and planning for EDF’s fisheries work in the United States, with particular focus on New England, where she resides.

Her passion for bringing lasting stability and change to fisheries yields tangible results. In her previous roles at EDF, she led the Pacific Oceans program team to transform the Pacific Groundfish fishery from a federal disaster to a certified sustainable fishery; and worked as the Oceans Program’s regional director in New England.


Johanna has a M.A. in Energy and Resources Group from University of California Berkeley and a B.A. in History and Environmental Studies from Yale University. Prior to joining EDF, she led a campaign to defeat a dam project in the longest free flowing river in Sierra Nevada, and worked on negotiations to restore flows for salmon recovery in one of California’s major river systems.
