After completing my residency and earned my medical degree in Paris in Otolaryngology, I was able to join the pediatric ENT team of Prs Teissier and Van Den Abbeele at the Robert Debré hospital in 2019, where I dedicate a large part of my activity to hearing loss in children, including the cochlear implants procedures. I met Dr Laurianne Cabrera and Pr Christian Lorenzi and I began to have an interest in the development of auditory perception in children, a field of research that interests me especially for the possibilities of clinical improvement for children I see in my daily clinical practice.  I moved to Seattle in 2022, to work with Pr Jay Rubinstein’s team, for a research year focused on the auditory perception in subjects with hearing loss due to the STRC mutation. In November 2022, I started a PhD with Dr. Laurianne Cabrera, with a project on the developmental trajectory of auditory processing and speech perception in noise in normal hearing children and children with hearing loss between 5 and 10 years old.

Ongoing project

Linking early phonolexical acquisition and later vocabulary development

In this project, we test the proposal that a crucial milestone in language acquisition is reached when infants discover which sounds (consonants versus vowels) are more important at the lexical level in their native language, leading to an acceleration of subsequent vocabulary development.

Development of the auditory system and speech perception in infants- BabySIN 

On the one hand, the cerebral processing of different acoustic variations of sounds is studied in 3-month-old infants using the electroencephalography technique. On the other hand, the ability to perceive speech in noise in these infants is measured using an observation technique.

Proccesing phonological information while learning and recognizing words

It has been proposed that consonants carry more weight than vowels in lexical processing. Given the timing of acquisition observed in French, we have proposed that this consonant bias emerges in connection with phonological and (proto)lexical acquisition, a hypothesis we are currently testing.

Predicting language outcomes in typical development

We explore how elementary perception and learning mechanisms are linked to language acquisition. To this end, we test infants on different perception and learning mechanisms, at different stages of their development and up to 2-3 years of age.

Language acquisition in atypical development

Knowing the mechanisms underlying typical language acquisition also makes it possible to explore whether or not these mechanisms are present in populations with atypical language acquisition and could be involved in their learning difficulties.

Lexical-semantic development

Our studies aim to understand the neural mechanisms underlying this development in monolingual and bilingual children.

Acquisition of phonological biases in lexical processing

We aim to understand how different types of sounds, as well as their arrangements within the words of a language, influence the acquisition and lexical processing of French, German, and Franco-German bilingual speakers.
