Involved with the Jeunes Réformateurs Libéraux from his teenage years, he worked from 1995 to the early 2000s in the offices of Éric André and then François-Xavier de Donnea. Elected to Uccle municipal council in 1997, he became alderman for Finance in 2005, later adding Economy, Youth, Sport and Green Spaces to his responsibilities.

From 2014 to 2018 he sat in the Brussels Parliament, where he chaired the Infrastructure Committee. In September 2017 he became mayor of Uccle, a role confirmed after the 2018 and 2024 elections.

On 14 February 2026, after more than 600 days of negotiations, he was appointed to lead the new Brussels executive. He has since served as Minister-President of the Brussels-Capital Region and, since 4 March 2026, as Minister for Research in the Government of the Wallonia-Brussels Federation.
