Sibyl Schaefer is an internationally recognized leader in digital preservation focused on the resilience of digital stewardship in the face of environmental change. She leads the NDSA Climate Watch Working Group, which monitors climate science to assess risks to digital preservation infrastructure and practice, bridging climate research and information stewardship.
She has published and presented widely on digital preservation, climate change, archives, and storage. Schaefer serves as Climate Data and Digital Preservation Librarian at the University of California, San Diego, where she has managed the Chronopolis digital preservation service for over a decade.
She is a founding member of both the Digital Preservation Storage Criteria initiative and the Digital Preservation Services Collaborative, and has been involved in early community efforts such as the Digital Preservation Network (DPN) and DuraCloud. She is also an active, long-standing contributor to the international iPres community.
Prof. Emanuele Bellini is an Associate Professor at the University of Roma Tre and a Visiting Academic at the University of Cambridge, Department of Computer Science and Technology. His research spans Cyber Resilience, Human-Cyber-Physical Systems, Critical Infrastructure Protection, and Trust Computing. He is also the founder of the emerging field of Cyber Humanities, and his current research investigates the security and protection of Digital Heritage, as well as the counteraction of Cyber Cognitive Operations targeting Cultural Heritage, as part of the broader challenge of safeguarding human knowledge and identity in the digital age.
Prof. Bellini serves as Chair of the IEEE SMC Technical Committee on Cyber Humanities and Vice-Chair of the IEEE SMC Technical Committee on Homeland Security. He is also Co-Chair of the IEEE International Conference on Cyber Security and Resilience (IEEE-CSR) and the IEEE International Conference on Cyber Humanities (IEEE-CH). His work bridges technical and humanistic perspectives on digital systems, addressing challenges in the resilience, trust and sustainability of complex socio-technical critical ecosystems. He is the author of over 90 peer-reviewed publications and an active contributor to international standards and policy bodies in cybersecurity.
Nanna Bonde Thylstrup is Associate Professor of Modern Culture at the University of Copenhagen. Her research examines the politics and ethics of datafication, machine learning, and digital infrastructures, with a particular focus on how data loss shapes contemporary digital societies. She is Principal Investigator of the ERC-funded project Data Loss: The Politics of Disappearance, Destruction and Dispossession in Digital Societies (DALOSS).
Rather than treating loss as a technical failure, her work explores how loss is actively produced and how it structures knowledge infrastructures, governance, and cultural memory. Empirically, she studies machine‑learning practices, public‑sector data systems, digital archives, and emerging technologies such as quantum computing, using interdisciplinary methods from cultural analysis, STS, archival research, and digital methods. Her research has appeared with MIT Press, Stanford University Press, and in leading journals, and she is a frequent keynote speaker at international conferences.
