RESEARCH

(Last update: 2023)

I am a theoretical astrophysicist interested in a vast range of problems related to celestial mechanics and dynamical astronomy. My research aims to understand the formation, architecture and evolution of planetary systems, both around the Sun and other stars. To do this, I employ a synergistic approach that primarily involves the development of mathematical models and theoretical frameworks (e.g., based on celestial mechanics and Hamiltonian dynamics), coupled with the design and deployment of numerical algorithms and simulations,  but also by being involved with and continually guided by observational data.

More specifically, my research specializes in investigating how gravitational interactions between planets and astrophysical disks in general (such as the gaseous protoplanetary disks in which planets are born, or the left-over debris population of asteroids and comets) influence the evolution and dynamics of planets and, along the process, sculpt observable features within such disks.
