In response to growing demand for secure, responsible clinical data sharing across Europe—and the increasing complexity of the evolving regulatory and research environment—Vivli has appointed Jennifer O’Callaghan as Executive Director of Vivli Europe, starting April 16, 2026.
Jennifer will lead the newly established Netherlands-based stichting (foundation), bringing deep expertise in clinical data sharing and the governance of responsible secondary use of clinical research data. Her experience spans roles as a research funder, advisor to multi-stakeholder consortia, and executive within global pharmaceutical organizations.
Leading the European organization, Jennifer will shape strategy and engage partners to enable greater access to high-quality data for researchers across Europe. She will ensure that activities align with the region’s regulatory frameworks and drive initiatives to expand collaboration among industry, academia, and policymakers.
“Europe is at a pivotal moment for clinical research data sharing, and Jennifer brings a rare depth of knowledge in this rapidly evolving field,” said Vivli’s Chief Executive Officer, Rebecca Li. “Strong regional leadership is critical as we accelerate research and expand access to trusted data that can improve patient outcomes. Jennifer’s leadership will be instrumental in advancing Vivli’s mission, scaling impact, and strengthening partnerships across the region.”
Jennifer has been involved with Vivli for over a decade, serving on the foundational working group that established high standards for patient privacy, governance, and transparency while fostering collaboration across pharma, biotech, academia, and the research community to produce new insights.
“At a time of surging demand for data, Europe faces the dual challenge of increasingly complex regulation and the need to balance patient privacy with responsible data innovation, including AI,” said Jennifer O’Callaghan, Executive Director of Vivli Europe. “Vivli Europe will play a central role in meeting this challenge through responsible data sharing in compliance with EU legislation.”
