Mathieu Colléter is an agronomic engineer specialized in fisheries sciences and a PhD in marine ecology. He thereafter worked as a postdoctoral fellow within the research programs Sea Around Us and Nereus at the University of British Columbia (Vancouver, Canada). His work focused on the modeling of marine ecosystems and the impacts of fishing and climate change. Wanting to work more at the interaction between science and public policy, Mathieu returned to France to follow a one-year Master’s degree in environmental policy at SciencesPo Paris. He then worked for three years in an environmental NGO as ‘Science & Policy Officer’, developing and leading advocacy campaigns at the European level. Thanks to these experiences, Mathieu developed a research interest on the inclusion and structuring of European small-scale fishers in European fisheries policies. He will investigate this topic within the Ocean Nexus international research program and will be hosted at the Institut National Polytechnique (INP, Toulouse, France) and the Institut du Développement Durable et des Relations Internationales (IDDRI, Paris, France).
