I am a second-year PhD student at Heriot-Watt University (Edinburgh), under the supervision of Alessandro Sisto. Previously, I was awarded a Studentship at the Scuola Normale Superiore of Pisa, and I completed a Master's degree at the University of Pisa.
Here you can find my CV in English and in Italian.
Five useless facts about me
- I performed in the play Mathopoly: an academic dystopia (FULL VIDEO).
- I made a visual novel videogame for my friends' Bachelor graduation (caveat: the game is in Italian and full of dull inside jokes).
- I'm supporting several charity organisations, including Amref, Amnesty International, and Save the Children.
- As a child, I uploaded some Minecraft gameplays on Youtube.
- I work in Geometric Group Theory, and I especially study Hierarchically Hyperbolic Spaces, which are those spaces sharing the same "hyperbolic features" as Mapping Class Groups of surfaces (for an overview on HHS see e.g. this survey by my supervisor). My PhD project investigates which algebraic, geometric, and algorithmic properties of a HHG can be detected by looking at its quotients, and conversely which features of a HHG are enjoyed by its quotients. If you want to have a more in-depth overview, you can see the final report of my first or second year of PhD.

Where to find me next:
From the 8th to the 13th September I'll be at the Ventotene International Workshop.Registered talks:
- (16/04/2025) G&T Seminar in Harbin (China). The FIRST LECTURE is an handwavy introduction to hierarchical hyperbolicity, while the SECOND LECTURE focuses on random quotients of mapping class groups.
- (06/06/2024) "World of GroupCraft" minitalk, about a combination theorem for geometric subgroups of mapping class groups (VIDEO)
- (28/05/2024) Advancements in Hierarchical Hyperbolicity, on some properties of quasi-isometries in hierarchically hyperbolic groups (VIDEO)
