Neuroscientist exploring how we move, balance & adapt to weightlessness đ | Parabolic flights | Vestibular | Space sickness
After completing my academic training across the universities of Grenoble, Aix-Marseille, MontrĂ©al, Laval (Qc, CA), and Paris, I had the opportunity to join the CNRS in Bordeaux in 2009. My research focuses on how the brain combines signals from the inner ear, the eyes, and the body to control movement and equilibrium. Iâm also interested in the disorders atht could result from it, especially in space sickness and how humans adapt to altered gravity environments.
I regularly conduct human experiments during parabolic flights aboard Novespace Zero-G aircraft, supported by the French space angency (CNES). I enjoy designing and building custom experimental devices for both hypogravity research and clinical studies at the Plateforme dâAnalyse du Mouvement, where I serve as technical lead. My goal is to help improve safety, performance, and comfort for people moving both on Earth and in space.
