# Research
After obtaining a bachelor degree in Trento in 2016 I have completed the
[ALGANT](https://algant.eu) Master Program (Milano and Leiden), with
special focus on number theory and algebraic geometry. I then moved on to
obtain a joint PhD at the universities of Luxembourg and Leiden, under
the supervision of [Antonella Perucca](http://antonellaperucca.net) and
[Peter Bruin](https://www.math.leidenuniv.nl/~pbruin).
I have collected in this page the list of papers I puplished during my PhD,
as well as theses (Bachelor, Master, PhD). See [my talks page](../talks)
for a list of slides and notes of my talks.

Supervisors: Antonella Perucca, Peter J. Bruin.
[Thesis: [pdf, 1.2Mb](phd-thesis.pdf);
