Présentation
Jean-Sébastien Guez est scientifique senior à l'Institut Pascal, Université Clermont Auvergne (UMR UCA CNRS 6602). Il est un ancien élève ingénieur de Polytech'Marseille, diplômé en 1999. Il a obtenu son doctorat en génie biochimique et microbiologie appliquée à l'Université de Lille. Il travaille dans la mise au point, la compréhension et l'optimisation des systèmes de production de molécules à haute valeur ajoutée par voie biotechnologique. Les principaux domaines applicatifs visés: agro-alimentaire, pharmaceutique et énergie. Il est co-auteur de 30 publications scientifiques, 2 brevets et plus de 60 communications internationales. Toujours soucieux de valoriser ses travaux de recherche, il est à l'origine de plusieurs transferts de technologie. Il a été associé de l'entreprise LipoFabrik, créée en 2012, et cofondateur de BioUpp, en 2024.
