Telefónica Scientific Research (TSR) is an industrial, multidisciplinary research group founded in 2007. We pursue rigorous, reproducible research that informs real-world telecommunications products and services. Our interests span artificial intelligence (including generative AI, large language models and agentic systems), network optimisation, distributed systems and protocols, privacy-preserving and ethical AI, and early exploration of emerging technologies. We publish openly where possible, contribute to standards, and maintain internal prototypes and production integrations used by Telefónica’s Operating Businesses.

"Advance fundamental and applied AI research across disciplines, exploring its societal implications and pushing technological boundaries, with a focus on strategic areas to accelerate innovation in Telefónica's key products and services."

• Promote the exchange and integration of knowledge across teams and disciplines.
• Act as a conduit for technological innovation and responsible IP generation.
• Foster a high-performance environment that values rigor, reproducibility and continuous improvement.
• Partner with academia to steer research toward impactful, open scientific directions.

• Advance fundamental and applied AI research (foundations, applications and societal implications) with an interdisciplinary approach.
• Develop core AI methodologies and technologies that support Telefónica’s strategic priorities.
• Advance the theory and practice of safe, ethical, and privacy-preserving AI; embed these principles in our work and disseminate them to international research and practitioner communities.

• Conduct foundational and applied research addressing both near-term industry needs and long-horizon opportunities.
• Produce open, well-documented code, reproducible artifacts and clear experimental records to accelerate adoption and independent evaluation.
• Translate scientific outcomes into deployable solutions, standards contributions and intellectual property when appropriate.
• Promote safe, ethical, and privacy-preserving AI across Telefónica and the wider community.
• Build sustained collaborations with academia, industry partners and product teams to maximize research impact.

• Open‑source implementations, research code and reproducible notebooks.
• Prototypes, proof of concepts and integration examples.

Since 2007 our group has grown from a handful of researchers to a compact team that balances curiosity and utility: producing publications, patents and funded projects while ensuring research outcomes can be validated, reused and, when ready, deployed.
