I am a postdoctoral researcher in James Turner’ laboratory at the Francis Crick Institute (London, UK) supported by a HFSP-LT fellowship. My scientific interests include developmental biology and cell fate choices, specially from a transcriptional regulation perspective. I obtained my Degree in Biology from the Autonomous University of Madrid (Spain) in 2012. As an undergrad student I joined Miguel Manzanares’ laboratory at CNIC (Madrid, Spain) to study the regulation of the trophectoderm lineage in the mouse preimplantation embryo. I stayed in the same lab to perform a PhD thanks to a “FPI-Severo Ochoa” fellowship, and I focused on the transition of the totipotent embryo towards the activation of the first lineages. During my PhD, I had the opportunity to carry out a short stay in Kat Hadjantonakis’ lab at the Sloan Kettering Institute (New York, USA) learning live imaging. Currently, I am studying epigenetic mechanisms regulating X-chromosome inactivation during mammalian evolution.
