Neuroscientifique explorant comment nous bougeons, gardons lâĂ©quilibre et nous adaptons Ă lâapesanteur đ | Vols paraboliques | SystĂšme vestibulaire | Mal de lâespace
AprĂšs avoir complĂ©tĂ© ma formation acadĂ©mique dans les UniversitĂ©s de Grenoble, Aix-Marseille, MontrĂ©al, Laval (Qc, CA) et Paris, jâai eu lâopportunitĂ© de rejoindre le CNRS Ă Bordeaux en 2009. Mes recherches portent sur la maniĂšre dont le cerveau combine les signaux provenant de lâoreille interne, des yeux et du corps pour contrĂŽler le mouvement et lâĂ©quilibre. Je mâintĂ©resse aussi aux troubles qui peuvent en rĂ©sulter, et particuliĂšrement au mal de lâespace et Ă lâadaptation des humains aux environnements de gravitĂ© modifiĂ©e.
Je mĂšne rĂ©guliĂšrement des expĂ©riences sur des humains lors de vols paraboliques Ă bord des avions ZĂ©ro-G de Novespace, avec le soutien du Centre National des Ătudes Spatiales (CNES). Je conçois et fabrique des dispositifs expĂ©rimentaux sur mesure pour la recherche en hypogravitĂ©, ainsi que pour des Ă©tudes cliniques sur la Plateforme dâAnalyse du Mouvement, dont jâassure la responsabilitĂ© technique. Mon objectif est de contribuer Ă amĂ©liorer la sĂ©curitĂ©, la performance et le confort des personnes en mouvement, aussi bien sur Terre que dans lâespace.
