Constance Bommelaer de Leusse has more than 20 years of experience in digital policy, technology, research and education. She currently serves as Project Liberty’s Institute Executive Director. Affiliated to Georgetown, Stanford and Sciences Po universities, this international institute is advancing timely, actionable research on ethical technology and serves as a meeting ground for technologists, social scientists, policymakers and leaders from the public and private sectors. The institute’s mission is to ensure that digital governance is prioritized in the development of new technology and embedded in the next generation of the web.

She is also a member of the Scientific Committee of the Digital Governance and Sovereignty Chair at Sciences Po, and teaches digital governance on a part-time basis. 

Constance started her career working for the French prime minister’s services (2003-2006) on information society issues. She then joined The Internet Society (2006-2022), the international NGO founded by Vint Cerf, the father of the Internet. In her role of Vice President of institutional relations and empowerment, she led the organization’s international partnerships and policy work across stakeholder communities. She also conducted training and learning activities, empowering the next generation of tech leaders to build an internet that creates opportunity and supports the public interest.

Constance has been instrumental in developing new internet governance institutions. She notably founded the Internet Technical Advisory Committee to the Organisation (2006) for Economic Co-operation and Development (OECD), facilitating the participation of global technical and academic communities into international policy discussions. In 2013, she was seconded to UNESCO to help develop their internet governance strategy. She co-authored the UN Internet Universality concept, i.e. Rights-based, Open, Accessible and Multistakeholder. The latter has, since then, been used as a foundation to support the evolution of digital policy frameworks at the national and regional levels.

Constance has served on a number of committees including the World Economic Forum Internet For All Steering Committee, and the UN Secretary-General’s Multistakeholder Advisory Group of the Internet Governance Forum (IGF).

Constance holds a master’s degree in law from the Paris Panthéon Asass University, a post-graduate degree in EU politics from Sciences Po, and a diploma in management from the London School of Economics (LSE). She grew up in the United States and has lived in Switzerland. She is currently based in Paris with her husband and their three children.
