Ph.D. Thesis
I am currently doing my Ph.D. thesis at the Institut Camille Jordan (Lyon), under the supervision of Thomas Blossier (ICJ Lyon) and Zoé Chatzidakis (ENS Paris).
Visite Lyon's logic group website.
My research interest is Model Theory. More precisely, I am interested in dp-minimal expansions of the group of integers, for instance expanding the group of integers by p-adic valuations.
I also study expansions of fields with generic predicates for groups. Such expansions give examples of NSOP1 theories. More generally I am interested in NSOP1 expansions, this is my current thesis subject.
