My research program is focused on the characterization of the molecular and cellular processes, which control the biogenesis of the sperm flagellum together with the signaling pathways, which regulate sperm motility and metabolism, overall conferring the fertilization potential. For this purpose we combine biochemistry, proteomic analysis, cell biology, molecular biology and genetics. In addition, in collaboration with national and international departments specialised in Reproductive Biology, we develop several programs aiming at defining the enetics and pathophysiological mechanisms associated with human male infertility. In parallel, we establish therapeutical strategies of male infertility and investigate novel contraceptive strategies targeting sperm cells.
