Activités de recherche

Je développe des approches nutritionnelles innovantes, translationnelles et collaboratives ciblant de nouvelles voies impliquées dans le dysfonctionnement de l’appareil locomoteur (notamment les tissus ostéo-articulaires) pour préserver la mobilité et améliorer l'espérance de vie en bonne santé. Je suis également co-fondateur de la start-up Clinic’n’Cell qui propose une innovation clinique ex vivo. Cette nouvelle approche associant métabolisme humain et biologie cellulaire fournit des données humaines robustes concernant les bénéfices santé d'un produit de manière plus rapide, plus abordable et plus mécanistique (mode d'action chez l'homme) que tout essai clinique conventionnel. Utilisant les métabolites humains (bioactifs circulants et biodisponibles) cette approche est plus physiologique que n'importe quel test in vitro. Elle permet aussi de s’affranchir de l’expérimentation animale.

I develop innovative, translational and collaborative nutritional approaches targeting new pathways involved in the dysfunction of the musculoskeletal system (notably osteoarticular tissues) to preserve mobility and improve healthy life expectancy. I am also co-founder of the start-up Clinic’n’Cell which offers ex vivo clinical innovation. This new approach combining human metabolism and cell biology provides robust human data on the health benefits of a product in a faster, more affordable and more mechanistic way (mode of action in humans) than any conventional clinical trial. Using human metabolites (circulating and bioavailable bioactives), this approach is more physiological than any in vitro test. It also allows us to avoid animal experimentation.
