PhD Cognitive Psychology  

I am associate professor (lecture) at the Université Grenoble Alpes (UGA) in the Department of Psychology. I carry out my research activity at the Psychology and NeuroCognition  Lab (LPNC). Since October 2018 I am a junior member of the Institut Universitaire de France (IUF).



Language skills require anatomo-functional interactions with other cognitive functions such as perception and action, executive processes, social cognition and memory. A current challenge for cognitive neuroscience is to better understand these interactions between cognitive domains and take advantage of this knowledge in clinical neurorehabilitation to improve language abilities. Accumulated behavioural and neuroimaging evidence suggests that linguistic information processing could be shared within a larger machinery which encompasses other cognitive functions. My scientific project (LINK project) aims to perform a fine-grained characterization of the anatomo-functional interactions between the ‘specialized’ or canonical language network and three other cognitive systems:  motor-action, executive function and the mentalizing systems. To evaluate these interactions, I address four main questions:  How? Where? When? and Which? How each cognitive ability (supported by each of these convitives systems) interacts with language system?; Where do these interactions take place? (in terms of cerebral substrate); When do they occur in terms of brain dynamic? Which are the neural structures, previously delineated, in which causal links with language performances are observed? (oppening new windows for a more applied research). To do this, an interdisciplinary approach is adopted, constructing and evaluating a set of cognitive tasks and using different behavioural and neuroimaging methods (e.g., eye-tracker, functional neuroimaging; fMRI, neurophysiology; intracranial-electroencephalography-iEEG, and neurostimulation; TMS). We expected to provide an integrative neurocognitive model of language and open new windows for language rehabilitation.
