After training as an engineer and completing a thesis at ENSTA Bretagne, Guillaume started a career in the automotive industry before joining the liquefied natural gas industry for some fifteen years. He’s now in charge of a research group dedicated to materials at Air Liquide, where he contributes to the development of new technologies and helps customers in their decarbonization efforts. He’s very committed to his role as manager, and talks in this video about his projects, as well as his studies at ENSTA Bretagne.

In his thesis, Pierre-Yves seeks to identify when and how a fracture appears between two very different materials: a metal and an elastomer, such as rubber. With his research’s direct application being tires, Pierre-Yves performs experiments on representative samples of vehicle tires to study interface failures between the rigid part (the cord or structure) of the tire and the flexible part (rubber).

A keen sailing enthusiast, Pauline enrolled at ENSTA Bretagne for its close ties with the maritime world and its naval architecture course. “If I hadn’t got into ENSTA Bretagne, I really don’t know what I would have done. It really was my first, and only, choice.” Today, she is working in the field of wind-powered maritime transport and its decarbonization, while personally preparing for a solo offshore sailing race: the Mini-Transat.
