Claire Wyart

Wyart was born into a family of scientists. Her mother, Françoise Brochard-Wyart, is a prominent French physicist and a professor at the Curie Institute.[1] Her father, Pierre-Gilles de Gennes, was a Nobel-prize winning physicist.[2] As their father was mostly absent, Wyart and her siblings were raised by their mother, though Claire thought of him as "the pillar who held our family together".[2][3]

Wyart studied at the École normale supérieure in Paris.[4] She then undertook a PhD in biophysics at the Université Louis-Pasteur (now University of Strasbourg), which she completed in 2003.[4] Working in the lab of Didier Chatenay,[5] she studied small networks of controlled architecture.[6]

Wyart did five years of postdoctoral research at the University of California, Berkeley between 2005 and 2010.[6] She worked for a year in Noam Sobel's lab, investigating the effects of smelling compounds in body secretions.[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.[6]

In 2011, she started her own lab at the Institut du cerveau et de la moelle épinière (ICM, Brain and Spine Institute) in Paris.[6] Wyart has received international funding for her research, from bodies such as the European Research Council, the Human Frontier Science Program and the National Institutes of Health.[1] Her team investigates how neuromodulatory pathways of the central nervous system (the brain and spinal cord) affect locomotion and posture. Her lab has three main areas of research: the effect of neuromodulation and peptide release on reticulospinal neurons, and on neurons in contact with the cerebrospinal fluid (CSF); the links between CSF and body axis formation and scoliosis; and new strategies to treat spinal cord trauma.[6] In an interview in 2015, she explained that her aim was to understand how to reactivate motor circuits in humans.[1]

Her lab's particular focus is ciliated neurons which contact the CSF; such neurons integrate both mechanical and chemical signals, and project onto spinal cord motor circuits.[3] Along with brain circuits and reflexes, these neurons represent a third circuit governing locomotion.[3] The morphology and markers expressed by these neurons, discovered in zebrafish, are conserved in other animals including mice and macaques.[7][8] Wyart's team has also demonstrated that these neurons can detect the curvature of the spinal cord.[9][8]

In collaboration with her former PhD student Olivier Mirat, Wyart launched ZebraZoom, a software to analyse zebrafish larvae behaviour.[10]

She serves on the advisory board of Current Biology,[11] on the board of directors of the FENS-Kavli Network of Excellence,[12][13] and on the scientific council of the Fondation pour la Recherche Medicale (FRM).[14]

During the COVID-19 pandemic, she collaborated with Marie-Claude Potier to develop a screening test for the virus using sputum and saliva samples.[15]

While studying for her PhD, Wyart ran a science workshop for children twice a month at the Exploradome museum.[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] This work was rewarded with a "Défi Jeunes" award.[16] With her team at the ICM, she uses zebrafish larva to teach primary and middle school children the basics of development.[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.[17][18][12] The website was subsequently translated into multiple languages.[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. We hope to inspire our colleagues around the world to join and help in this fight against both the virus’ spread and misinformation for the public good.”[17]
