Galactic astronomy

Latest news: I was recently awarded the IAU best PhD prize in the division for galaxies and cosmology

Short bio

I am currently a Flatiron research fellow in the Nearby Universe group at the Center for Computational Astrophysics (CCA) at the Flatiron Institute in New York City.

I obtained my PhD in 2022 at the Astrophysics Research Institute (Liverpool, UK).

I am what people call a “spanish-geordie”.


I am primarily interested in the formation and evolution of the Milky Way and its Globular Cluster system, and how we can apply this knowledge to further understand how other galaxies in the Universe form. More recently, I have become very interested in galactic dynamics, statistics/machine learning, understanding the nature of dark matter, and resolved stellar populations of the Local Group.

I primarily analyse/model big data from either large-scale surveys of the Milky Way (e.g., Gaia, APOGEE, GALAH) and/or data from sophisticated cosmological numerical simulations (e.g., FIRE, EAGLE, E-MOSAICS)
