Our team and line of research

Yasmine Cantaut-Belarif is a CNRS Research Associate at the Paris Brain Institute. She joined the team of Claire Wyart to investigate the role of cerebrospinal fluid during development. She showed that a conserved polymer bathing in the cavities of the brain and spinal cord, named the Reissner fiber, controls the geometry of the posterior axis in developing zebrafish embryos. Since 2020, her work aims to unravel the mechanisms by which this acellular thread influences the morphogenesis and the alignment of the body at embryonic and post-embryonic stages.

The position

We are seeking to appoint a postdoctoral researcher to join a 3-year research programme in developmental neuroscience funded by the Agence Nationale de la Recherche (ANR). The aim of the programme is to understand how the Reissner fiber bathing in the cerebrospinal fluid shapes the geometry of the body and the alignment of the spine during post-embryonic stages. More specifically, we seek to (i)identify the mechanisms by which this fiber is maintained over time in the brain and spinal cord cavities, (ii)to dissect the fundamental molecular and cellular pathways controlling the maintenance of this structure influencing body and spine shape. To address these questions, the candidate will combine the power of genetics and in vivo state-of-the-art imaging in zebrafish and develop approaches including gain-and-loss of function as well as structural and functional analysis of transgenic lines.

Contract & Starting date

One-year renewable contract (three years total) Starting: January 2022 (flexible)
