Présentation

Actuellement directeur adjoint du laboratoire BiOSSE - Biologie des Organismes, Stress, Santé, Environnement - à Le Mans Université, je co-anime l'axe de recherche MIMMA-Métabolisme et Ingénierie des Molécules des Microalgues et Applications. J'ai obtenu un doctorat en Physiologie et Biochimie de la Nutrition à l'Université de Bourgogne en 1991. En 2018, j'ai présenté mon Habilitation à Diriger des Recherches en Biochimie et Biologie Moléculaire à Le Mans Université. Mes activités de recherche se développent dans deux domaines : - la régulation du métabolisme des lipides et des acides gras polyinsaturés des microalgues marines; - l'utilisation des molécules bioactives des microalgues dans la santé et la prévention des maladies. Le premier domaine de recherche est centré sur la réponse des diatomées marines soumises à un stress nutritif, afin de déterminer quels mécanismes cellulaires sont impliqués dans le transport, le stockage et l'utilisation des lipides. Le deuxième domaine de recherche est davantage une approche appliquée grâce à des collaborations avec des partenaires industriels pour la valorisation des molécules produites par les microalgues et leurs bénéfices pour la santé.
