I received a Ph.D. in Pyisics at the University of Barcelona in 2016 working with the Lyman alpha forest. I then moved to France for a couple of postdocs in Marseille and in Paris. There I also worked with quasar identification using machine learning techniques. Since 2021 I will be working at IFAE with Andreu Font Ribera on the Lyman alpha forest cosmology. My field of interest is not only cosmology (with the Lyman alpha forest), but also the study of the Intergalactic and Circumgalactic Media and how it relates to galaxy formation and evolution. I am also member of the international collaborations Dark Energy Spectroscopic Instrument (DESI) and the William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE).
Towards sub-percent measurements of the high-redshift expansion
The standard ACDM model for cosmology predicts the existence of Dark Energy, but we do not understand its nature yet. Alternative models attempt to explain the observations by changing the laws of gravity and without any need for Dark Energy.
I am using measurements of the Baryonic Acoustic Oscillations (BAO) peak to measure the expansion of the Universe and unravel the mystery of Dark Energy. In a bit more detail, I am part of the DESI and WEAVE teams whose goal is to create the most detailed 3D map of the universe of galaxies, quasars, and the Intergalactic Medium. I will focus on the study of the Intergalactic Medium as it is not only interesting for cosmological studies, but also to construct a consistent picture of its role in the formation and evolution of galaxies right when the star formation rate is occurring!
