Leandro is an expert on galactic dynamics and has worked on several topics in the interface between theoretical modelling, N-body simulations, and observational data. Specific projects he has worked on include different relaxation processes driving collisionless systems to stationary states, the role of massive clumps in the early evolution of disk galaxies, the Milky Way’s merger history, galactic seismology, and frequency analysis of orbits in galactic potentials with a focus on bar resonances. He is currently a co-chair of the DESI Milky Way Survey. Leandro’s current main interests are on the Milky Way's dark matter halo shape, the role of resonances in shaping stellar populations in the Galaxy, the merger history of Andromeda, and on advancing theoretical tools for dynamical analyses.
