Research activities:

Our themes of research are focused on stem cells, metabolism, testis physiology, the understanding of the spermatogenesis process, cell signaling, epigenetic, environmental exposure as well as germ cell cancer (website: https://www.gred-clermont.fr/directory/team/fr/equipe-13-environnement-spermatogenese-pathophysiologie-et-heredite/).

Since 2010, we have focused our efforts on decrypting the molecular mechanisms underlying the links between bile acid metabolism and impaired male fertility. Our studies are mainly focused on understanding the roles of the bile acid receptors FXRalpha and TGR5 in testis.
