I am cognitive (neuro)scientist interested in cognitive control mechanisms at the behavioral and neural level.
For instance our ability to create and manipulate a mental image, attend to a specific feature or sensory modality or invoke a percept from memory. What are the shared mechanisms, resources, and their limits, across these cognitive operations? What are their temporal dynamics? Finally, how and why these processes can be impaired or occasionally fail (e.g. attentional lapses, sustained attention deficits, cognitive control impairments)?
I study these phenomena using psychophysics, neuroimaging (EEG, fMRI), multivariate pattern analyses techniques (MVPA) and modelling.
After completing my masters degree in Paris (CogMaster) I did my PhD under the supervision of Leila Reddy and Rufin VanRullen at the CerCo lab in Toulouse (France). The topic of my thesis was on the effect of learning, at different timescales, on neural representations of visual objects using EEG, fMRI and multivariate pattern analysis techniques.
From January to December 2017 I held a post-doctoral position at the Human Factors lab of ISAE-Supaéro (french Institute of Space and Aeronautics). The project was on developing methods to study and monitor attentional resources, cross-modal attentional allocation and mental workload with Frederic Dehais and Raphaëlle Roy.
I currently hold a post-doctoral position in the Experimental Psychology department at Ghent University. I am working with Tom Verguts and Durk Talsma on the neural basis of instruction following. We investigate the neural mechanisms, such as oscillations and synchronization, that support cognitive control by establishing functional network for task performance. For that purpose we use computational modelling, EEG connectivity measures to study synchronization (i.e. phase-locking) and cross-frequency (see Tom Verguts' model of cognitive control (2017): Binding by random bursts: A computational model of cognitive control). Some recent findings from this project are available as a preprint (see below).
