Since March 2019, he is the director general of the Paris Peace Forum organization, an independent NGO he founded in 2018 under the impetus of French president Emmanuel Macron.

The Paris Peace Forum is an annual event that aims at promoting new rules and solutions to address the global challenges of our time.

A graduate student from École normale supérieure de Saint-Cloud and Sciences Po, Vaïsse earned his PhD in history in 2005 and his habilitation à diriger des recherches in 2011.

In 2006, he co-authored Integrating Islam: Political and Religious Challenges in Contemporary France[4] (Brookings Press) with Professor Jonathan Laurence, a book named “2007 Outstanding Academic Title” by the American Library Association and subsequently translated into French.

In 2017, President Emmanuel Macron tasked Vaïsse with outlining the contours of an annual event that would respond to the growing woes of multilateralism by convening all actors of global governance once a year around major initiatives and concrete projects.
