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. He has 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 and, finally, 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) and Network Function Virtualization (NFV), Traffic Engineering and Distributed control schemes, having participated in several R&D projects funded by the European Commission’s Framework Programmes (H2020, FP7, FP6, CELTIC…) and the Spanish research programmes (Proyecto I+D, Red Temática, CENIT, PROFIT). He has led several research grant projects and technology transfer activities with Industry actors (such as Telefónica, KDDI R&D Labs, or KDDI Corporation).

He has co-authored 4 book chapters, over 150 journal and conference papers and 4 IETF RFCs. He has been Technical Programme Committee member of major international conferences in the field of optical networks such as ECOC, OFC, IPOP or ICC; a regular reviewer for IEEE Communications Magazine, IEEE Network, IEEE/OSA Journal of Lightwave Technology or IEEE/OSA Journal of Optical Communications and Networks. He is a IEEE Senior Member (2012), a member of the Communications Society and Internet Society and a contributor of the IETF CCAMP, TEAS and PCE working groups.
