I earned my Ph.D in Neurophysiology in 2002 at the Université Claude Bernard in Lyon, while working with Patrice Fort and Pierre-Hervé Luppi on the in vitro characterization of neurons located in the anterior hypothalamus responsible for the induction of slow wave sleep. In collaboration with Pr. Muhlethaler’s laboratory at the University of Geneva (Switzerland), I discovered that these neurons and those in the waking systems are able to inhibit each other, illustrating a reciprocal inhibitory interaction. In 2003, I joined Jean Rossier’s laboratory at the Ecole Supérieure de Physique et de Chimie Industrielle (ESPCI), in Paris as a postdoctoral fellow. By coupling patch-clamp electrophysiological recordings with single cell RT-PCR multiplex technique I uncovered cortical excitatory peptidergic pathways between GABAergic interneuron subtypes and glutamatergic pyramidal cells. Appointed as Associate Professor in Physiology at the ESPCI in 2005, I contributed to identifing and characterizing the role of neocortical GABAergic interneurons in mice. My projects are completely in line with previous work I carried out during my PhD. The major question that I am addressing is "What are the cellular and molecular mechanisms responsible for the induction of sleep?"
