He graduated in Mathematics at the University of Pisa in October 2016. In November 2016, he joined the Ph.D in Mathematics in the same university, under the supervision of Prof. Giovanni Federico Gronchi. In October 2018 he visited the University of Barcelona for a period of four months, collaborating with Prof. Ángel Jorba.
In the summer 2019 he was elected as an ESR in the Stardust-R Project at the Faculty of Mathematics of the University of Belgrade. His work will focus on the dynamics and the criticality of small asteroids.
In his spare time he likes running, hiking and reading.
Our current knowledge of the orbital and size distribution of a very small asteroids, down to few tens of meters in size may not be fully appropriate. Some available estimations are based only on indirect evidence, such as disruption rate of main belt asteroids. The asteroid belt is also subject to evolutionary processes, but so far, no model has included all the important processes affecting asteroid evolution. Besides, new models still have to be successfully tested against known constraints.
The project will be aiming to better understand the orbital and size distribution of small asteroids, below 100 meters in size. To achieve project’s goals the ESR should study dynamical and collisional evolution of asteroids in this size range, combine this in a single self-consistent model, and test the model against all available constraints.
In addition, the ESR will work on characterization of near Earth asteroids and should define a criticality index that provides a measure of how easy the asteroid is to deflect with a given deflection method, and how interesting the asteroid is to explore and to exploit.
