Petter Holm is a professor in fisheries and resource management at UiT – The Arctic University of Tromsø, Norway. His research interests include organizational conditions for collective choice; institutional change processes in the fisheries; fisheries governance; the mobilization of science in management decision making; fishermen’s ecological knowledge and the relationship between science and local knowledge. In GAP he has served as WP leader, together with Douglas C. Wilson Kongshøj, for the systematic investigation of the progress and performance of the GAP case studies.    Dr. Maria Hadjimichael’s interest lies in the study and understanding of the governance of the commons, particularly marine and coastal commons. Concerned about issues such as the ‘stealing of the seashore’ and ocean grabbing through neoliberal mechanisms, she has founded the website reclaimthesea.org. She worked as a postdoctoral researcher at the Innovative Fisheries Management Institute of Aalborg University in Denmark. Her PhD (Bangor University, U.K.) explored the human dimension of the European fisheries governance. She worked on numerous interdisciplinary EU funded projects and conducted fieldwork in the UK, Spain, Denmark, Greece, Cyprus, the US and Chile. Sebastian Linke is associate professor in Environmental Social Science at the University of Gothenburg, Sweden. He has studied the relationship between science and policy for sustainable development with a focus on EU fisheries and marine management. He is particularly interested in the roles of expertise in environmental politics and the co-creation of knowledge by scientists and other actors under new forms of environmental governance. Dr. Steven Mackinson is the Chief Scientific Officer for the Scottish Pelagic Fishermen’s Association. He began his career working with Canadian herring fishermen in the mid-1990s, linking academic research with fishermen’s knowledge. Ever since he has been interested in building stronger collaboration among scientists, fishermen, and policy makers and was leader of the GAP projects. Prior to 2016, he worked for 17 years at the UK government marine research laboratory – the Centre for Environment Fisheries and Aquaculture Science (Cefas) where his research included using ecosystem models to investigate impacts of management and environmental change on ecosystems and fisheries, acoustic studies on fish, understanding the effects of renewable energy plans on fishermen.
