Sergio did his undergraduate degree in Biological Sciences at the Autonomous University of Madrid. During this time, he undertook a year studentship in Miguel Manzanares’ lab at the CNIC (Madrid), to study the regulation of the trophectoderm lineage in the mouse preimplantation embryo. After doing a Master in Molecular and Cell Biology at the Autonomous University of Madrid, Sergio joined Miguel Manzanares’ lab as a PhD student thanks to a “FPI-Severo Ochoa” fellowship in 2014. He focused on the transition of the totipotent embryo towards the activation of the first lineages. During his PhD, Sergio carried out a short stay in Kat Hadjantonakis’ lab at the Sloan Kettering Institute (New York) learning live imaging techniques.
In 2019, Sergio joined James Turner’s lab as a postdoc and in 2020, he was awarded an HFSP Long-Term fellowship. His project focuses on the epigenetic mechanisms regulating X-chromosome inactivation during mammalian evolution using the opossum as a marsupial model organism.
Furthermore, Sergio is interested in science communication, and he is a member of the Young Embryologist Network organising committee and a member of preLights, the preprint highlights service hosted by The Company of Biologists.
