Marion Baraban performed her PhD in Dr Schneider-Maunoury lab, supervised by François Giudicelli. She then studied in vivo the axonal mRNA transport and local translation in neurons of the zebrafish embryo. She is currently a post-doc in Pr. Lyons group in Edimburg studying how neuronal activity regulates the formation and function of myelinated axons. She performs in vivo imaging that reveals distinct roes for local ca2+ signalling in myelin sheath stabilisation and growth. Her work was recently published in Nature Neuroscience and illuminates brightly the usefulness of the zebrafish model.
