I am a PhD student in Set Theory at the Universities of Trento and Barcelona, under the supervision of Joan Bagaria i Pigrau. The topic of my PhD research is Generic Absoluteness: which sentences are preserved by generic extensions of the universe?

Previously, I have obtained a Bachelor’s degree and a Master’s degree in Mathematics at the University of Trento. My Bachelor’s degree supervisor was professor Stefano Baratella, while my Master’s degree supervisor was professor Joan Bagaria i Pigrau.

Both theses were on the topic of the Axiom of Determinacy, with two different approaches: in my Bachelor’s thesis I studied the consequences of AD on the reals, while in my Master’s thesis I studied the proofs of consistency of AD from large cardinals.

At the UB, I co-organise (together with Jeffrey Bergfalk) the Marvelous Set Theory Reading Course, an informal reading course where we study set theory together. I also lend a hand when needed for teaching the courses in Basic Set Theory, Combinatorial Set Theory and Models of Set Theory.
