I'm a researcher in cognitive sciences at the Laboratoire Dynamique du Langage (CNRS). My main research interests are in language development and education. My research objective is to identify the biological mechanisms underlying the early development of speech perception and production in order to facilitate learning at school. To this end, I study the cognitive and neural bases of both language acquisition in children and language use in adults. My research combines multiple methodologies including behavioral studies, neuroimaging (M/EEG, fMRI, sEEG, fNIRS), and computational modeling.


I am a CNRS researcher at the Dynamic Language Laboratory (Université de Lyon), in Lyon, France. \\ My general interests are neuroscience and linguistics, with emphasis on the neural basis of speech perception. I use multiple non-invasive (M/EEG, fMRI) or intracranial (ECoG, sEEG) techniques to record neuronal activity. In order to provide optimal findings, I apply well-founded approaches and methods from signal processing. My aim is to understand the rhythmic fluctuations of neural excitability and the synchronization mechanisms in ensembles of neurons in order to show the kind of temporal filters the brain applies in speech perception. My research combines theoretical and experimental fields, and is practical to both ordinary and pathological perception (signal conveyed by a cochlear implant for everyone with profound deafness, individuals with dyslexia).

RESEARCH INTERESTS


 

Audio-Visual Integration in Speech Perception. Aim: to characterize the acquisition of audio-visual integration skills in infants from 3 to 36 months Hypothesis: a long exposition to audio-visual speech signals enables the integration mechanisms to play a canonical role in the perception of speech

 

Synergistic Interaction of the sensory and articulatory motor systems. Aim: to determine whether the oscillatory integrative mechanisms involved in speech perception boost the development of the oscillatory mechanisms underlying articulatory movements of the mouth for speech production, and vice versa. Hypothesis: enhancing inter-areal coherence in the theta and gamma bands between the audio-visual integrative cortical area and the articulatory motor system is a biological marker of concomitant improvement in production and perception skills.
