Professor Jean Le Bideau is a professor at the University of Nantes, at the Institut des Matériaux Jean Rouxel (IMN). His work focuses on organic-inorganic hybrid materials; more specifically, in recent years, it has been aimed at confining liquids in macroscopically solid materials: solid, but with liquid properties, these materials have applications in biomedical and electrical energy storage. In addition to his teaching and awareness raising actions on ecology, his international responsibilities for the university, he actively participates in collective actions of the university and the socio-economic world, with a particular interest in the maritime world. He previously spent ten years at the University of Montpellier as an associate professor, and two years at Michigan State University as an associate researcher, after obtaining a PhD and an engineering degree in materials sciences.

Laurent Lebreton is Head of Research at The Ocean Cleanup. His research group focuses on understanding the sources, the transport and the fate of ocean plastics by leading large scale field expeditions, developing advanced numerical models and investing in remote sensing technology. Ultimately, Laurent is interested in closing a global mass balance budget for plastics in our oceans as a direct tool for the rapid implementation of a wide range of mitigation strategies from local to global scale. Laurent started his research on ocean plastics in 2010 where he tried to predict the formation of ocean garbage patches using numerical models on his computer at his home office in Raglan, Waikato. He’s involved in many groups working in the field of Marine Litter, including GESAMP and other UNEP funded working groups.

Dr. Marc Lucas is a senior oceanographer at CLS. He holds a BSc in ocean Science from the University of Plymouth UK, an MSc in Oceanography, and a PhD in Physical Oceanography both from the University of Southampton, UK. After 3 post Docs in France and Germany mostly focused on numerical modelling, he joined the CLS team dedicated to providing metocean services for Offshore Energy. This involved working on the use and interpretation of combined Satellite In Situ and numerical model data. He then joined the environmental downstream application unit focusing on issues such as sargassum invasion and marine plastic. In his current position, he supervises innovative project focusing on Earth Observation data and the acquisition of high quality in situ data for satellite applications.

Dr. Maes is a physical oceanographer from the French National Institute of Research for Sustainable Development (IRD) based at the Laboratory for Ocean Physics and Satellite remote sensing (LOPS). His research is focused on the dispersion of marine debris, through the characteristic scales of ocean dynamics, and the source scenarios for regional or global scale - either of physical origin, such as river inputs, or of societal origin, including the population density living near ocean coasts. Dr. Maes is a member of the SCOR International Working Group 153 "FLOTSAM (Floating Litter and its Oceanic TranSport Analysis and Modelling)", of the IMDOS community; his activities take place also within the GDR Polymères&Oceans and the recent PPR Plastoc, with the idea to promote an integrated system of the oceanic pollution of the oceans.
