While continuing his mathematical research activities, he started publishing literary works from the 1980s on: movie criticism in the Belgian magazine Regards, a theater play in 1999, and novels from 2002 on. His novel L'Ordre des jours, published in 2008 by Héloïse d'Ormesson, received the Prix Erckmann-Chatrian the same year.
