Sylvie REMAUD is working as an assistant professor since 2013 at the National Museum of Natural History (CNRS 7221, Paris). She has a specific expertise in studying how a neural stem cell can generate two daughter cells with different identities (neuronal versus glial cell fate). She contributed to demonstrate that thyroid hormone acts as a neurogenic switch in the young adult mouse brain. Currently, she is studying how do thyroid hormone regulates the neuron/glia balance during the early postnatal life and later, in the ageing mice.
