Thierry studied the flute at the Royal Conservatory of Mons, graduating in 2008. He then branched off into mathematics and obtained a Master's degree at the University of Cambridge in 2012, another at the University of Brussels in 2013, followed by a Ph.D. at the Université catholique of Louvain in 2017. He followed with 2 post-doctoral fellowships in Germany, one at the Max Planck Institute for Mathematics in Bonn in 2018 and the other at the University of Giessen in 2019.

His research focused on the classification of simple totally disconnected topological groups, approaching the problem through the prism of algebraic groups on local fields. Programming has always fascinated him, starting with Visual Basic in his childhood. After his postdocs, he trained himself in different programming languages (C++, Python, Scala, Java) as well as some machine learning techniques.

Thierry joined B12 in December 2020 as an Associate. He goes through phases with his hobbies and is currently a fervent follower of B. K. S. Iyengar inspirational school of yoga.
