Plixavra Vogiatzoglou is a Postdoctoral Researcher at the Amsterdam Center for International Law (ACIL) and the Institute for Information Law (IViR), as part of the Law and Governance of Quantum Technologies Research group. Her research focuses on the concept of digital sovereignty, which is used to convey the urgency of being autonomous in the digitised world and reducing dependencies on foreign companies, infrastructures, technologies, and services. The EU seeks to assert its digital sovereignty by domestically investing in critical infrastructures and technologies, such as artificial intelligence and quantum tech, pursuing geopolitically strategic partnerships, and promoting EU values. Plixavra examines the EU's policies on digital sovereignty by taking into account EU law, international legal theory and critical legal perspectives.

Plixavra holds a PhD from the KU Leuven Centre for IT & IP Law (CiTiP). Her dissertation questions the lawful establishment of mass data surveillance for predictive policing frameworks in light of the EU's powers to provide security whilst safeguarding fundamental rights, particularly privacy, data protection, effective remedy, fair trial and presumption of innocence. At CiTiP, she further worked on national and European projects, conducting research on how emerging technologies developed and deployed in the field of security impact privacy and data protection rights. Plixavra is also a certified lawyer in Greece and holds an LLM in Intellectual Property and ICT law from the KU Leuven Faculty of Law and an LLM in International Studies from the Aristotle University of Thessaloniki Faculty of Law.
