Vince serves as Promotion and Coordination Vice-Chair and Associate Rapporteur of Q5 for ITU-T Study Group 15. He actively participates in the following ITU-T Questions (Q2, Q5, Q6, Q7, Q8). Prior to joining Corning, Vince was an US Naval officer and nuclear engineer serving in the US submarine force.  
Takashi Matsui
Group Leader, Access Network Service Systems Laboratories​, NTT Inc

Dr. Takashi Matsui is currently a Distinguished Researcher and Group leader at Access Network Service Systems Laboratories, NTT, Inc., working on advanced optical fiber and cable technologies including optical fibers for the space division multiplexing. He has been actively involved in international standardization activities in ITU-T SG15 and IEC TC86 and serves as a Program Chair at OFC2026.
​​​​Alexis Carbo Mesegue
Alcatel Submarine Networks (ASN) 

Alexis Carbó Meseguer joined Alcatel Submarine Networks (ASN) in 2018 after completing his Ph.D. at Nokia Bell Labs and Télécom SudParis. At ASN, his work focused first on the physical characterization and performance optimization of optical fiber transmission systems, including the study of Signal Droop, GAWBS, and EEPN effects in long-haul links, as well as the development of automation techniques to streamline subsea open cable commissioning. Also, he has been deeply involved in the modeling and experimental validation of optical amplifiers, proposing a digital-twin-based framework to accurately predict submarine cable capacity. More recently, Alexis led groundbreaking experiments demonstrating the world’s longest transmission using a 2-core multicore fiber (MCF), reaching a record distance of 20,512 km, thus validating its feasibility for transoceanic systems. His research also encompasses the study of emerging fiber technologies, particularly the comparative analysis of multicore and hollow-core fibers, to assess their potential for future high-capacity submarine networks. In 2022, he was named Distinguished Member of Technical Staff (DMTS) by Nokia, recognizing his outstanding technical contributions to Network Infrastructure development. 

Paulo Serra
Head of Innovation Management, ANACOM

Paulo Serra has over 30 years of experience in the telecommunications sector. Currently Head of Innovation Management at ANACOM, the Portuguese National Regulatory Authority, he leads a multidisciplinary team that fosters innovation across key areas of the digital ecosystem — including submarine cables, data centres, artificial intelligence, virtual worlds, quantum technologies, and 5G/6G — in alignment with ANACOM’s regulatory mission. At the beginning of his career at ANACOM, he played a pivotal role in significant developments within Portugal’s communications landscape, such as the introduction of digital terrestrial television and 3G networks. He later dedicated a decade to European and international regulatory fora, including direct support to the BEREC presidency in 2015. From 2016 to 2022, he coordinated ANACOM’s QoS Unit, overseeing networks performance and user experience metrics across the communications sector. Before joining ANACOM, Paulo held commercial and marketing positions at France Telecom and Telecom Italia. He holds a degree in Electrical and Computer Engineering (Telecommunications and Electronics), an MBA, and a Master’s in Business Administration.
