Rémi Cousin received his degree in engineering from l’Ecole Nationale Supérieure des Mines de Nancy in 2005. After specializing in physical oceanography through internships at Mercator-Océan, Toulouse, France, and Universidad de Concepción in Chile, Cousin worked for CLS (Collecte Localisation Satellite), a subsidiary of CNES, to develop user-friendly tools to run and post-process Mercator ocean models dedicated to operational oceanography. He then worked at the Jet Propulsion Laboratory, Pasadena, California, developing a public outreach and education website on ocean salinity in the context of the NASA satellite mission Aquarius, and conducting research to support the activities of the OurOcean group, on regional ocean models. Since 2008, Cousin has been a member of the IRI Data Library, which disseminates science-based climate information to its user community. To fulfill this task, Cousin assists in research activities, and engages with user communities through collaborative work or training workshops.
