Current situation:

Ingénieur de Recherche Hors Classe (Research Engineer). Aix-Marseille University (AMU). Technical Director of the MEG laboratory.

Short resume:

JM Badier graduated from Université de Technologie de Compiègne (UTC, engineer 1985, PhD 1991). He has been working at the Brain Research Institute at UCLA, Hôpital Ste Anne Paris (Epilepsy Research INSERM U97) and Rennes 1 University before to join the Aix-Marseille University In 1997 as research engineer (Ingénieur de Recherche).

He worked on the first MEG platform in France (Rennes 1992). He is a specialist in acquisition and processing of electrophysiological signals. He is in charge of the MEG system of Marseille since the opening of the Marseille platform (2007).

He is involved in several educational courses, giving lectures in engineering schools and masters.

He has been member of the scientific council of the University.

His current research is concerned with cerebral dysfunction in epileptic patients explored by EEG, SEEG and MEG, as well as the test of the new MEG (Col CEA-Leti) and EEG (Col BEL Lab. Ecole des Mines de St Etienne) sensors.
