About

I am currently a Marie Curie Fellow at Università degli Studi di Milano in Milan.

Research interests: theoretical astrophysics, accretion discs dynamics, protoplanetary systems, black hole binaries, fluid and dust dynamics (and the numerical methods to describe them); radiative processes in astrophysical environments and radiative transfer Monte Carlo methods; celestial mechanics.

During my career. I focused mainly on the problem of the satellite-disc interaction and its effects on the dynamics of both protoplanetary discs and black hole binary systems.

Interests and Skills

Theoretical Astrophysics

General Research interests: Astrophysical fluid dynamics, satellite-disc interaction, radiation transfer, celestial mechanics.
Protoplanetary discs: Planet formation. Dynamics of gas+dust accretion discs. Effects of the presence of planets on the disc structure and grain growth in overdense regions. Modelling the EM appearance of protoplanetary discs. Planet migration and planet eccentricity evolution.
Black hole binaries: Last parsec problem and disc driven eccentricity growth before the gravitational wave inspiral. Suppression of the gas accretion by tidal torque. Formation of non-axisymmetric structures modulating EM luminosity. Circumprimary and Circumsecondary disc dynamics. Black hole spin alignment.
