My research activities focus on the analysis and the interpretation of electrophysiological signals
recorded in patients suffering from drug-resistant partial epilepsy. Clinical objectives are the localization
of the epileptogenic zone and the definition of its organization, prior to surgery.
The first research axis (analysis) aims at developing methods able to quantify the information
conveyed by electrophysiological observations (EEG, MEG and intracerebral EEG). Tackled questions
relate to signal processing and statistics, in nonstationary and nonlinear situations. Many aspects are
dealt with such as the detection of transient events like epileptic spikes, the measurement of statistical
couplings between signals acquired from multiple sensors, the classification of signals based on their
time-frequency or time-scale representation.
