Since October 2025, I am a postdoc researcher at KU Leuven, Algebra Section, mentored by Raf Cluckers.
Before that, I was an IST-BRIDGE & Marie Skłodowska-Curie fellow in Tim Browning’s group, ISTA.
I completed my PhD in Summer 2023, under the supervision of Emmanuel Peyre at Institut Fourier, Université Grenoble Alpes.
I graduated from École polytechnique in 2020 (X2016).
mathematical interests
Classical and motivic aspects of a certain number of topics in
- algebraic geometry: Cox rings and applications (distribution of rational points on varieties, moduli spaces of curves, …), stacks of G-bundles;
- analytic number theory: circle method, harmonic analysis, zeta functions and their applications to geometry and arithmetics;
- logic: model theory for motivic integration and applications to arithmetics.

In my native language (French), my first name is gender neutral. Its pronouciation is close to that of Louis in English but is different: in ˈluːɪs you have to replace uː by əʊ (like the final o in tomato) to get ˈləʊɪs (and pronounce the final s if you did not). My pronouns in English are he/him/his/they/them/their. You can write to me in English, French, Spanish or Italian.
