The Scientific Committee

Le comité scientifique

The Scientific Committee is the symbol and ultimate guarantor of the quality of CESP audits and publications in France and abroad.
A space for discussing and evaluating the quality of audience measurements, it is involved in all discussions involving technical issues and methodological innovations related to measuring audiences, its aim being to robustly and transparently vouchsafe for the validity of the figures on which the industry bases its core activities.
The Scientific Committee is currently presided over by Guillaume Chauvet, who is a Doctor of Statistics and a lecturer and researcher at ENSAI.
