Research Interets

I am a neurologist working in the field of the epilepsy, with a specific interest in intracerebral evaluation of focal epilepsy using Stereo-EEG. My research interests concern the understanding of the neural basis of face perception using intracerebral recordings and intracerebral electrical stimulations in epileptic patients. I am convinced that a multi-modal approach combining intracerebral electrophysiology, functional neuroimaging and face perception impairments evoked by focal intracerebral stimulations or related to focal epilepsy may provide significant advances for understanding face perception.

I am currently a neurologist at the University Hospital of Nancy (CHRU-Nancy, France).
