Céline is a permanent researcher (CR1) with the INSERM. She did her Ph.D. in the Mouse Molecular Genetics Unit at the Pasteur Institute, on the characterization of genomic elements involved in the initiation step of random X-chromosome inactivation using targeted mutagenesis in mouse embryonic stem (ES) cells. Then she did a three-year postdoctoral training in Wendy Bickmore’s lab in Edinburgh where she studied the nuclear re-organization associated with the activation of Hox gene clusters during mouse development using 3-dimensional fluorescence in situ hybridization techniques (3D FISH).
She joined Claire Rougeulle\\\’s lab in the fall of 2014. Her current project is to characterize the role of the Ftx lncRNA during mouse development.
