Stéphane Avril is a mechanical engineer, but his research focuses on the elasticity and resistance of arteries, and how this changes with disease or old age. This researcher from Mines Saint-Étienne is passionate about biology and has received a prestigious European Research Council (ERC) grant for the third time. This funding will support his next ambitious project: reversing the effects of aging on arteries by controlling mechanical wear. It represents a new phase in a journey at the interface between two disciplines.
