Other activities


I am taking part into the MATh.en.JEANS project. Its aim is to introduce some easy research problems to students of high school, and let them discover how to find proofs and collaborate together.

In 2019-2020, I am again supervising ten groups of students from Athénée Royal de l'Air Pur (Seraing), together with France Gheeraert and Laurent Loosveldt.

In 2018-2019, I was supervising a group of students from Athénée Royal de l'Air Pur (Seraing), together with Laurent Loosveldt.

In 2017-2018, I was supervising groups of students from Collège Saint-Benoît Saint-Servais (Liège), together with Stéphanie Aerts, Célia Cisternino, Céline Esser and Julien Raskin.

I am also taking part into the Math A Modeler project, which aim is to initiate young people (from 10 years old) to research in Discrete Mathematics, by letting them play with educative games.
