Short Biography

After completing a Master’s degree in Cognitive Science at the École Normale Supérieure, Dr. Legendre pursued a PhD under the supervision of Prof. Sophie Schwartz at the University of Geneva, investigating the processing of emotional signals during sleep. He then joined the lab of Prof. Giulio Bernardi at the IMT School for Advanced Studies Lucca (Italy) for a two-year postdoctoral position, focusing on the induction and quantification of local sleep. Dr. Legendre is currently based again in Prof. Schwartz’s lab, where he studies autonomic rhythms during sleep. His research explores how brain state shapes sensory processing and examines whether autonomic signals—such as heart rate, breathing rate, and pupil size—can serve as a readout of underlying brain states.
