Welcome to my Webpage!
My main subject of research is Mathematical Logic.
More precisely, I do research in Model Theory (Stability Theory in Abstract Elementary Classes), connections with Geometry (model theory of sheaves, model theory of modular invariants), connections with Set Theory, Infinitary Logic.
I also work in the Philosophy of Mathematics.
