Engineering Sciences

Xavier Costa-Pérez is ICREA Research Professor, Scientific Director at the i2cat Research Center and Head of 6G Networks R&D at NEC Laboratories Europe. His research focuses on the digital transformation of society driven by the interplay of mobile networks and AI. His team generates research results which are regularly published at top scientific venues, produces innovations which have received several awards for successful technology transfers, participates in major EC R&D projects and contributes to standardization bodies. He has served on the committees of several conferences, published papers of high impact and holds tenths of granted patents. In 2021 he served as Editor at IEEE Transactions on Mobile Computing, IEEE Transactions on Communications and Elsevier Computer Communications journals. Xavier received both his M.Sc. and Ph.D. degrees in Telecommunications from UPC.

Research interests

The ever-wider availability of technologies such as mobile networks, artificial intelligence, cloud services, data analytics and ICT platforms is dramatically altering the way we live, work and interact – in what is usually referred to as the Fourth Industrial Revolution. The upcoming Beyond 5G disruptive technologies represent a key pillar for enabling this digital revolution unfolding around us. In contrast to previous mobile network generations, a key new aspect for the mobile industry moving forward is the need to expand the mobile ecosystem to also incorporate industry verticals like automotive, manufacturing, smart-grids and health. While early research and field-trials results are promising,  The AI-driven  automation of mobile networks for a cost-efficient digital transformation (DX) is still at its infancy and will require of a huge research effort to deliver on the DX promises in the next decades.
