Really about me

If you really want to know more, I'm from Castellò de la Plana, a small town at the Levante (east coast) of Spain. I grew up there, happily close to the Mediterranean sea, until I started my university studies. After that, I never really settled anywhere more than a handful years.

In my free time (when I still have some of that) I do long-distance running, train Shotokan karate, and dance - salsa and bachata. I used to play drums, but given how ungratefully bulky they are, I recently settled down for a more convenient Spanish guitar. More quiet interests are cooking (you have to try my paella Valenciana - it's the real thing!), movies, video games (remember Sonic the hedgehog?), or devouring books whenever time permits.


About me

I'm a Postdoctoral Researcher at the Institute of Astronomy and the Kavli Institute for Cosmology, both associated with the University of Cambridge. My research aims to improve our understanding of the role played by magnetic fields, radiation and cosmic rays in the formation and evolution of galaxies. I am also particularly interested in the origin of magnetic fields in galaxies and in our Universe. While we are aware that they are a fundamental in shaping the interstellar medium of the galaxies we observe at the present day, or even at high redshift, their theoretical understanding is still an active field of research.

For my research, I generate cosmological magneto-hydrodynamical simulations of galaxies and the cosmos, working mostly with the code RAMSES. My simulations combine the many ingredients required to ensure the formation of realistic galaxies. That implies combining large cosmological scales with fine and ambitious small-scale spatial resolutions. I employ various sophisticated models developed by my collaborators and me to capture magnetic processes, cosmic rays, stellar radiation, star formation, stellar feedback, metals, cooling and heating, etc. As part of my research, I work to improve our numerical methods, also exploring and developing novel algorithms to solve many of the standing questions regarding magnetic fields in our Universe. 

Before my doctorate, I did an MSc in Theoretical Physics and Astrophysics at the Universitat de València, where I also got my Physics degree. I was fortunate to have all my degree costs covered by a CMU San Juan de Ribera scholarship. During my bachelor degree, I did an Erasmus year at the University of Leeds, enrolling their MPhys programme

- somehow managing to still squeeze in all the credits required to complete my undergraduate degree. During these years, I was fortunate to obtain various research scholarships (e.g. IAC, UV) that allowed me to do some research on theoretical, numerical, and observational astrophysics, as well as in experimental particle physics.


Before Cambridge

Prior to my current position, I obtained my Ph.D. in Astrophysics at the University of Oxford. I held a Hintze scholarship from the Oxford Hintze Centre for Astrophysical Surveys, doing my thesis with Julien Devriendt and Adrianne Slyz. My thesis was entitled 'Magnetic fields in and around galaxies'.



Magnetic fields

Ubiquitous in our Universe, magnetic fields affect the evolution of astrophysical environments across all scales. However, many of the most fundamental questions about them remain open. I try to give answer to some of those questions through magneto-hydrodynamical cosmological simulations.

Galaxy formation and evolution with magnetic fields, radiation, and cosmic rays

As part of my research, I try to understand what drives the global properties of galaxies and their  interstellar medium, as well as the processes that contribute shaping them, such as star formation or stellar feedback.
