In a few words

After training in developmental biology and genetics, Stéphanie LE BRAS prepared her thesis at Pasteur Institute where she studied the DDK syndrome in Charles Babinet’s unit. She then did her post-doctorate in the team of Mark Van Doren at Johns Hopkins University in Baltimore, US where she became interested in the development of germline stem cell niche in Drosophila.

In 2007 she was recruited as an assistant professor in Roland LE BORGNE team where she characterized cellular mechanisms regulating Notch signaling pathway, which controls cell fate acquisition during the asymmetric division of sensory organs in Drosophila. In 2015, she joined the team of Claude PRIGENT where she study the role of Aurora A in symmetric and asymmetric cell division in Drosophila.
