My research focuses on cosmology and more precisely on the large scale structure of the Universe, aiming to answer one of the most fundamental questions within the field of fundamental physics and cosmology in the last 20 years: what is driving the late-time accelerated expansion of the Universe. I obtained my PhD in Physics at the Institut de Ciències del Cosmos at the University of Barcelona in 2012 developing theoretical and statistical tools to analyse and understand large-scale structure data. In 2012 I moved to the Institute of Cosmology and Gravitation at the University of Portsmouth working as a postdoctoral research associate. My interests turned into analyzing and understanding spectroscopic galaxy data, specifically within the Baryon Oscillation Spectroscopic Survey (BOSS), and since 2014 as well within the extended Baryon Oscillation Spectroscopic Survey (eBOSS). On 2015 I continued my research at the Laboratoire de physique nucléaire et de hautes énergies (LPNHE) in Paris thanks to the award of the Institut Lagrange de Paris Fellowship (ILP). In 2018 I was awarded with the prestigious Junior leader ‘la Caixa’ Fellowship which allow me to develop my research at the Insitut de Ciències del Cosmos at the University of Barcelona, where I have begun to work within the Dark Energy Spectroscopic Instrument (DESI), whose first light is at the end of 2019.
