I’m an Associate Researcher at Observatório Nacional (ON, Brasil).
Before joining ON (in 2025), I was a postdoc at the Steward Observatory (University of Arizona, US), at the University of Michigan (US), at the University of Central Lancashire (UK), and at Universidade de São Paulo (USP, Brasil). I earned my PhD at USP, during which I spent a year working at the Institut d’Astrophysique de Paris (France). I also completed my undergraduate degree at USP.

My focus is on galactic dynamics and the structure and evolution of galaxies, at the interface of theoretical modelling, N-body simulations, and observational data.

Topics I have investigated include collisionless relaxation processes of gravitational systems, the role of massive clumps in the early evolution of disk galaxies, the Milky Way’s merger history, galactic seismology, and the orbital support and evolution of galactic bars.

My current interests center on the properties of the Milky Way’s dark matter halo, the role of resonances in shaping stellar populations in the Galaxy, and the merger history of Andromeda.

I currently serve as co-chair of the DESI Milky Way Survey working group - check the DESI-MWS DR1 stellar catalogs, with radial velocities, chemical abundances, atmospheric parameters, distances etc.
