Claire Julie Liliane Wyart (born 16 February 1977) is a French neuroscientist and biophysicist, studying the circuits underlying the control of locomotion.

[5] She then worked in Udi Isacoff,[5] using optogenetics — the modulation of neuronal activity using light — to study the control of behaviour in zebrafish larvae.

[1] Her team investigates how neuromodulatory pathways of the central nervous system (the brain and spinal cord) affect locomotion and posture.

[5] After completing her PhD, she spent a year working for the Terma project in Nepal and India, teaching science in Tibetan schools by using practical experiments.

[5] During the COVID-19 pandemic, Wyart and her colleague Virginie Courtier-Orgozozo launched a website showcasing advice from experts and helpful tips for the public on how to stay safe.

[18][15] In an article by Michael Gross published in Current Biology, she is quoted as saying: "We deeply believe that it is the role of scientists to inform society and to provide the public with cues and methodology for them to be able to make better choices and to navigate safely in our new environment that we share with the SARS-CoV2 coronavirus.
