Our R&D team dedicated to offshore wind

Tessa holds a engineering degree in data science specializing in biostatistics from École Nationale de la Statistique et de l’Analyse de l’Information in Rennes, France. She joined France Energies Marines in 2024 to study the impact of climate change on wind resource in the framework of the 2C NOW R&D project. She is currently pursuing a PhD which focuses on quantifying uncertainties related to climate change and its application to offshore wind energy as part of the 2C MORE project.

In 2025, Alice graduated with an engineering degree from École Nationale du Génie de l’Eau et de l’Environnement de Strasbourg, France, and also holds a master’s degree in coastal and port engineering from the University of Cantabria in Santander, Spain. Following her final internship at France Energies Marines as part of the DIMPACT+ R&D project, Alice continued as a R&D engineer on a fixed-term contract for the same project. Her work focuses primarily on the simulation of breaking waves and the analysis of their impact. She is based in Chatou, at the Laboratoire d’Hydraulique de Saint-Venant, a joint facility between EDF R&D and the Ecole Nationale des Ponts et Chaussées.

With over 10 years of experience, Jean holds a PhD in physical oceanography, complemented by a European advanced master’s degree in renewable energy. He began his career as a research engineer at the CNRS. Then, he joined the Ecole des MINES ParisTech in the same type of position where, among other responsibilities, he initiated and coordinated the IREMARE project on the high-resolution characterization of marine renewable energy resources along the French coast. Since 2021, Jean has been working at France Energies Marines and currently holds the position of offshore wind project manager. In this role, he has deepened his knowledge in characterizing wind energy potential through his participation in various R&D projects such as CASSIOWPE and FARWAKES, as coordinator.

Youen has an academic background with a PhD in hydrodynamics. He was the R&D director of a private company, Open Ocean, for 8 years, and performed a lot of studies on numerical modelling, metocean statistics and offshore potential computation for offshore renewable energy sector stakeholders. He joined France Energies Marines in 2019 to manage the site characterisation module of the DTOCEAN+ European project. He is also involved as the manager of the French resources centre for ORE development RESCORE. He was then involved as the manager of RESCORE, the digital platform for data and tools developed by France Energies Marines. He coordinates the 2C MORE R&D project, and previously 2C NOW, which aims to assess the impact of climate change on offshore wind.

Mathieu holds a master’s degree in energetics obtained from the Université d’Orléans in 2022. He completed a PhD in physics of the atmosphere at École centrale de Nantes in 2025, where he has deepened his knowledge of numerical modeling of the atmospheric boundary layer in coastal area. He joined France Energies Marines in 2026 at the position of researcher in atmosphere modeling.

Now a PhD student in hydrodynamics at France Energies Marines, Sacha is a research engineer with eight years of experience. A graduate of INSA Rennes in mechanical and automatic engineering, then of ENSTA’s specialised master’s degree in marine renewable energy, he built an international career between the United States and Sweden before joining Ifremer. At Ifremer, he contributed to the development of an innovative method for reconstructing free surfaces in test tanks using a stereo video system. Since 2024, Sacha has been conducting experimental research as part of the DIMPACT+ project, dedicated to studying the forces generated by breaking waves through wave flume tests. His work lies at the intersection of hydrodynamics, the development of advanced experimental measurement methods and the challenges of offshore wind turbine design.

With over 10 years of experience, Fabien holds a degree in environmental monitoring and management, complemented by a PhD in ocean physics obtained from the École Doctorale des Sciences de la Mer in Brest, France, in 2013. He began his career at the French Naval Hydrographic and Oceanographic Service as a sea state expert, where he carried out different types of missions: setting up sea campaigns including data analysis and processing, improving the Vigilance Vagues Submersions operational system in partnership with Météo-France, participation in various civil and military research projects, and expertise to several French government departments. Fabien has been with France Energies Marines since 2020 and currently holds the position of metocean R&D engineer. In this role, he has deepened his knowledge of modelling wave impacts on offshore structures, modelling cyclonic sea states and ocean-wave-atmosphere interaction through his participation in various R&D projects such as DIME, DIMPACT, DIMPACT+, CASSIOWPE, and OROWSHI
