Inside EOSC

Yann Le Franc

This episode of Inside EOSC features Yann Le Franc, CEO of eScience Data Factory, work package leader for LUMEN, and head of secretariat at EUDAT. Yann traces his journey from computational neuroscience, where he built models of the spinal cord and worked at the International Neuroinformatics Coordinating Facility in Sweden, into the world of semantic web technologies and data management. He explains the foundational concepts of knowledge graphs and ontologies: how RDF triples represent subject, predicate, and object; how ontologies layer meaning onto otherwise structureless graphs; and why these technologies matter for both human navigation and machine reasoning. The conversation touches on the limits of triples when representing the messy nuance of human relationships, and on the work in FAIR Impact on aligning ontologies that describe the same concept differently across domains. We explore why knowledge graphs are valuable for AI, why grounding language models in structured, contextualised data produces measurably better answers, and why provenance and FAIR principles matter when ontologies are themselves models built by particular people for particular purposes. Yann reflects on the philosophical roots of ontology and the impossibility of a single universal model. The discussion turns to EUDAT's recent selection as a candidate node in the EOSC Federation, and the governance and sustainability challenges of providing transnational access to compute and storage across European borders. Yann also reflects on the unusual dual identity of scientist and entrepreneur, his decision to return to business school, and his growing focus on sustainable business models for European research infrastructures. The episode closes with a return to neuroscience: why our analogies for the brain are borrowed from computers, why LLMs are statistical machines rather than intelligent ones, and Yann's quiet conviction that science will save the world. ---------------------------------------- Hosted on Acast.

Enrica Porcari

This episode of Inside EOSC features Enrica Porcari, Chief Information Officer at CERN, a role she took on in January 2026. Enrica's path to leading technology at one of the world's foremost scientific institutions is anything but conventional. A social scientist by training, she began her career as a park ranger before spending three decades in humanitarian and development organisations, including the UN World Food Programme and CGIAR. She discusses what that outsider's perspective brings to CERN and why a laboratory dedicated to understanding the origins of the universe has, for the first time, chosen to create a CIO role and filled it with someone from outside the world of particle physics. The conversation explores the relationship between fundamental research and societal impact, from the unintended consequences of CERN's most famous export, the World Wide Web, to the deliberate, inclusive approach to quantum computing through the Open Quantum Institute. Enrica explains how this initiative brings together scientists, diplomats, the private sector and communities in the Global South to ensure that quantum technologies address sustainable development goals from the outset, rather than as an afterthought. We also discuss CERN's relationship with EOSC, European values of openness and collaboration, and why she describes herself as a "realistic optimist" about the future of technology in the service of humanity. ---------------------------------------- Hosted on Acast.

Julien Homo

This episode of Inside EOSC features Julien Homo, CEO and Data Architect of the French SME Foxcub, and the technical coordinator for the LUMEN project. Julien discusses his transition from large private-sector industrial environments to the collaborative world of European public research, sharing how his background in knowledge representation and artificial intelligence informs his work in building large-scale technical infrastructures. We delve into the technical heart of LUMEN, exploring the concept of the Data Mesh, a decentralised framework designed to foster interdisciplinary collaboration without the need for a single, massive central platform. Julien explains how this model allows diverse scientific communities, from molecular dynamics to social sciences, to share data products and services while maintaining their own specialised tools and cultures. The conversation also clarifies the distinction between data meshes and knowledge graphs, and why translating research data into "triples" is essential for connecting different discovery platforms across the EOSC ecosystem. Beyond the technical architecture, Julien reflects on the cultural and operational differences between private industry and public consortia. He examines the challenges of managing 21 partners and 7 million euros in public funding to create white-label solutions that remain flexible enough to adapt across different domains. Finally, we discuss the evolving role of LLMs and AI in knowledge exploration, the importance of "openness" for commercial innovation, and the story behind the name Foxcub. ---------------------------------------- Hosted on Acast.

Fotis Psomopoulos

This episode of Inside EOSC features Fotis Psomopoulos, Coordinator of the EVERSE project and Senior Researcher at the Centre for Research and Technology Hellas (CERTH). The discussion traces Fotis’s journey from electrical engineering into the life sciences, and his evolving understanding of research infrastructures, from an early focus on physical hardware to a realisation that infrastructures are fundamentally about communities and standardised services. We explore the often-overlooked role of software in the research ecosystem. Fotis explains why software has historically been treated as a 'second-class citizen' compared to data, and outlines EVERSE’s mission to elevate it through defined indicators of excellence and quality toolkits. He unpacks the distinction between Open Source and FAIR principles, and details the 'three-tier' hierarchy of research software, ranging from personal analysis scripts to critical community infrastructure. The conversation touches on the impact of AI on coding practices, where Fotis characterises AI as a collaborative partner rather than a replacement for human expertise. He also reflects on the importance of global collaboration, citing examples from African research contexts that offer valuable lessons for Europe regarding efficiency and software maintenance. The episode concludes with a look at the cultural shifts required to recognise software as a primary research output, and the inherent interdisciplinarity of 'writing with code'. ---------------------------------------- Hosted on Acast.

Klaus Tochtermann

This episode of Inside EOSC features Klaus Tochtermann, president of the EOSC Association and director of ZBW. The discussion traces Klaus’s early work in hypermedia in the mid-1990s, his move into digital libraries, and his long involvement in shaping what would become the European Open Science Cloud. He reflects on the shift from traditional library practice to large-scale digital infrastructures, and how this has altered both research behaviour and expectations. We explore how open science has changed over three decades, touching on social media’s early promise for scholarly communication, the relationship between FAIR data principles and broader questions of openness, and the challenge of maintaining trust in a climate shaped by geopolitical tensions around data. Klaus explains why data sovereignty has become central to Europe’s approach, and why sustainable funding and meaningful involvement of researchers are essential for EOSC’s future. He also outlines how EOSC might act as a model beyond Europe, and the difficult negotiations ahead as the next Framework Programme takes shape. He describes the need for deeper interaction between scientific infrastructures and industry, noting both mutual interests and the barriers that remain. The episode offers a reflective look at Klaus’s career of building new institutions and his thoughts on where science, technology and policy may be heading next, all framed by his commitment to openness, interdisciplinarity and practical support for researchers across Europe. ---------------------------------------- Hosted on Acast.
