Alfonso Alejandro Sanchez Macian Perez

Alfonso Alejandro Sanchez Macian Perez serves as an Associate Professor in the Telematics Engineering Department at Carlos III University of Madrid, specializing in cutting-edge telecommunications and cybersecurity research. His work spans optical networking, fault-tolerant systems, and space applications, with significant contributions to 6G infrastructure development and privacy-preserving data structures.

His research focuses on optical networking innovations for next-generation communications, including space-division multiplexing and multi-band migration techniques critical for 6G deployment. In cybersecurity, he investigates vulnerabilities in probabilistic data structures like Bloom filters and KMV sketches, developing countermeasures against privacy attacks. His space systems research addresses radiation-hardened memory architectures and FPGA reliability for spacecraft applications, with emphasis on error correction and fault tolerance.

As principal investigator for major projects including FUN4DATE Redes (2023-2026), Agile uLtra Low EnerGy secuRe netwOrks (2023-2026), and PROTEUS-6G (2024-2026), he leads EU and nationally funded initiatives advancing optical transport networks and sustainable high-capacity infrastructure. His publication record shows consistent high-impact output across IEEE Transactions and optical networking journals, with growing emphasis on 6G-enabling technologies since 2021.

His laboratory work centers on the Telematics Engineering Research Group at UC3M, collaborating with Telefónica Innovation Digital and European Commission agencies on photonic integrated circuits and non-terrestrial networks. Current efforts focus on programmable optical transport for 6G services and self-managed sustainable optical networks through the SEASON project.
