Axel spoke at the TEDxParcMontsouris conference that I organized on November 3, 2016 at the Cité internationale universitaire de Paris. Very available and very professional during the preparation of this event, Axel gave a very high quality talk that moved the 500 spectators present in the room! The YouTube video of his talk is also very successful (about 43,000 views to date!). Axel was able to convey a lot of emotion and inspiration in just a few minutes and left a mark on the audience. He is a very talented speaker.
