I am a young researcher in mathematics, soon working as an IST-BRIDGE & Marie Skłodowska-Curie fellow in Tim Browning’s group, ISTA, from December 2023.
Previously, I completed my PhD under the supervision of Emmanuel Peyre at Institut Fourier, Université Grenoble-Alpes.
mathematical interests
- moduli spaces of curves
- rational points/curves on varieties and variants such as Campana points/curves
- \(p\)-adic & motivic integration
- Grothendieck ring of varieties & related invariants
- birational geometry & applications to arithmetics
PhD thesis
My PhD project concerned the study of stabilisation phenomena occuring in the moduli space of rational curves on a nice variety (typically, a Fano variety), or more generally the moduli space of sections of a nice family above a smooth projective irreducible curve. I worked on a geometric analogue of the Batyrev-Manin-Peyre conjectures. The tools of motivic integration provide a nice framework to formulate this analogue; I studied, in a relevant ring of varities, the asymptotic behaviour of the class of the moduli space of curves of arbitrary large degree, for certain classes of varieties such as equivariant compactifications of groups or twisted products. My thesis also contains general predictions which are motivic analogues of the ones for rational points.
Keywords: moduli space, rational curves, Fano varieties, motivic Euler product.
Ce projet doctoral était financé par une allocation ministérielle AMX.

J’ai occupé un siège de représentant élu des doctorant.e.s au Conseil du Collège des Études doctorales de l’UGA de début 2021 à fin 2022, et j’occupe actuellement un siège de suppléant à la Commission Recherche de l’UGA. Ne pas hésiter à me contacter à ce sujet.
Je recommande vivement la lecture de l’étude scientifique sur la précarité financière des doctorants à l’UGA commandée par le CED à une équipe des laboratoires Pacte et LaRAC. Un chiffre à retenir : “l’absence de financement a concerné chaque année en moyenne 14% des doctorant.es” sur la période 2017-2021.
