I develop methods for the detection of transient events (epileptic spikes, HFOs), the estimation of statistical couplings between signals (brain connectivity), the classification of signals based on their time-frequency or time-scale representation.
Top: Depth-EEG signals recorded from human hippocampus and entorhinal cortex during transition to seizure activity in TLE.
Bottom: Time-frequency representation of depth-EEG signals showing a narrow-band fast activity (20-30 Hz) at seizure onset
My second research axis aims at explaining observed signals using physiologically-relevant computational models of neuronal systems at the origin of recorded activity.
I develop computational models at various levels of description, from microscopic (detailed networks) to macroscopic (neural mass and neural fields) level.

My research activity focuses on the analysis and the interpretation of electrophysiological signals recorded in patients with drug-resistant partial epilepsy. Clinical objectives are the localization of the epileptogenic zone and the definition of its organization, prior to surgery.
My first research axis aims at developing methods able to quantify the information conveyed by electrophysiological observations (from LFPs to scalp EEG).
