Présentation

L’efficacité de nos interactions sociales dépend de la combinaison des signaux sociaux, notamment le visage, le regard, la voix, la posture, etc. Une mauvaise identification, une expression erronée ou une mauvaise interprétation de ces signaux sociaux générer des comportements inadaptés dans la vie quotidienne.

Maître de conférences – HDR, mon programme de recherche se trouve au carrefour des sciences cognitives affectives, de la neuropsychologie, des interactions humain-machine et du traitement du signal social social. Il vise à comprendre le rôle des émotions dans la perception sociale et les interactions sociales. Il s’agit de comprendre comment les humains décodent et produisent les signaux sociaux au travers les expressions faciales, le regard, la voix, la posture, la distance interpersonnelle ou le toucher. J’explore comment ces processus évoluent tout au long de la vie ou varient en fonction de caractéristiques individuelles, par exemple dans certains syndromes cliniques ou en fonction des traits de personnalité.

En tant qu’enseignante dans le service de psychophysiologie-neurosciences, je suis passionnée par l’enseignement de compétences transférables à mes étudiants. Celles-ci vont de l’initiation à la recherche jusqu’aux neurosciences cognitives avancées, couvrant les programmes de licence et de master.
