Sylvie Rétaux works at CNRS and University Paris-Saclay, France. Dr Sylvie Rétaux is a neuroscientist and developmental biologist whose interests have shifted to evolutionary biology about 20 years ago. Her laboratory works on ecological evolutionary developmental biology of a cave-dwelling organism, the blind cavefish Astyanax mexicanus. Using an integrated approach combining embryology, neuroscience, behavior, and population genetics, she aims at discovering the mechanisms of adaptation to life in the dark.
