Ramon Casellas (Barcelona, 1975) graduated in Telecommunications Engineering in 1999 both from Technical University of Catalonia (UPC, Barcelona) and from the Ecole Nationale Supérieure des Télécommunications (ENST, Paris, now Telecom Paristech) in the framework of the Erasmus student exchange program (double degree, specialization in Communications (UPC) and Networks and Compute Science (ENST). He completed a PhD degree in Telecommunications in 2002, from the Ecole Nationale Supérieure des Télécommunications (ENST, Paris) funded by a CTI project with France Telecom Research and Development. He has worked as an undergraduate researcher at France Telecom Research and Development – FT R&D formerly known as Centre Nationale d’Etudes des Télecommunications (Issy les Molineaux, France) and British Telecom Labs (Ipswich, UK).

In 2002, he joined the Networks and Computer Science Department at the ENST as an Associate Professor (Maïtre de Conférences) and, in March 2006, he joined the CTTC Optical Networking Area, where he currently holds a Senior Researcher position. His research interest areas include GMPLS/PCE architecture, Software Defined Networking (SDN), Network Function Virtualization (NFV), Traffic Engineering and Distributed control schemes, with applications to Optical and Disaggregated Transport Networks.
