We study how neuronal identity, synaptic connectivity and circuit function emerge during development.
We are recruiting at postdoctoral, graduate and undergraduate level, funded by an Impulscience grant from the Fondation Bettencourt Schueller.
No two brains are wired exactly alike, yet they perform the same functions.
Variation appears at every scale: in gene expression, in cell number, in neuronal morphology, in the number and localization of synapses, yet function survives it. Explaining how is a question about development, because ontogeny is what accounts for the brain an animal ends up with: how much it can vary and still work, and what gives way when it does not, as in disease.
Each step during development constrains and enables the next, so the order in which events occur is part of the mechanism rather than a description of it.
We work on this in the Drosophila visual system, from cell fate specification and the emergence of synaptic connectivity to behavior: a brain small enough to study cell by cell, stereotyped enough that the same neurons can be identified in every animal, and accessible to technologies that reach subcellular resolution in vivo while simultaneously allowing analyses up to behavioral phenotypes.
What are the gene regulatory networks that specify neuronal identity, from neuroprogenitor divisions to differentiated neurons?

In this project, led by our collaborator Guillaume Isabel, we study how visual cues shape social learning.

The CBI is a multidisciplinary institute of 40 research teams, including a large community of several fly labs. Our lab sits at the interface of the Stem Cells and Developmental Biology and the Molecular and Cellular Neurobiology programs.
We are housed in a new building with access to CBI core facilities: a light imaging facility with 16 acquisition workstations — two-photon in vivo microscopy, spinning disk and scanning confocal, optical tweezers, super-resolution — behavior rigs, and a dedicated fly rearing facility.
Toulouse is the third-largest city in France and has the country's second-largest student population, across three universities. It sits an hour and a half from the Pyrenees in one direction and the Mediterranean coast in the other.
Small utilities we use at the bench.
Works out one bulk master mix for GoTaq G2 or Phusion HF, splits it across primer pairs with a safety margin, and builds the cycling program. Exports the bench sheet as PDF or Excel.
