RESEARCH PROFILE

Research areas and methods

My research focuses on the formation and dynamical evolution of natural satellites, planetary rings and small bodies in the Solar System and exoplanetary systems.

I work primarily with numerical simulations, including N-body, hydrodynamical and SPH methods, and compare the results with analytical models and observational data.
