About

Ramon Casellas is a leading researcher in the field of optical networking and 5G network slicing, with a particular focus on software-defined networking (SDN) and network function virtualization (NFV). His major contributions include pioneering work on the integration of optical transport networks with 5G core architectures, enabling dynamic, programmable, and efficient resource allocation. One of his most cited works, "5Gtango: A Beyond-Mano Service Platform" (2018, 27 citations), addresses the critical challenge of managing and orchestrating complex 5G services that span across humans, vehicles, and IoT devices, targeting verticals like eHealth and Industry 4.0. Casellas has also been instrumental in developing control and orchestration frameworks for multi-layer and multi-domain networks, significantly advancing the flexibility and scalability of next-generation infrastructures. His research has garnered widespread recognition, with cumulative citations exceeding 2,500, reflecting its profound impact on both academic and industrial communities. Notable achievements include his leadership in European research projects such as 5G-Crosshaul and METRO-HAUL, and his role as a co-author of several IETF standards. Casellas’s work continues to shape the evolution of 5G and beyond, making him a key figure in the transition toward fully virtualized, software-driven networks.
