Guillaume Ducoffe has passed his PhD in Computer Science recently, in Universite Cote d'Azur, France. Before this, he has obtained his Master from Ecole Normale Superieure de Cachan, France. His main research interest are algorithmic graph theory, combinatorics, algorithmic game theory and computational learning theory. He commonly uses this theoretical framework in order to study some information-sharing problems on large communication networks: such as the design of scalable routing protocols, and privacy and transparency issues of Big Data, to name a few.
