I am a Theoretical Cosmologist working in understanding the beginning and eventual end of our Universe. In particular, I am interested in studying how the primordial density seeds that populated the very early universe were generated. The generation of those primordial seeds should have left an inprint in the distribution of matter in the Universe, which can be traced by looking at different astrophysical observations; for instance, the Cosmic Microwave Background or the Large Scale Structure of the Universe, which can be further studied through Weak Lensing and Galaxy Clustering measurements. You can read my PhD thesis here.
For my work, I use Advanced Bayesian Inference techniques and Machine Learning algorithms. Furthermore, I am also interested in forecasting the performance of new experiments or new observables, for instance, Gravitational Waves.
Since 2018
Large Scale Structure and the Euclid mission
I am an active member of the Euclid Consortium and the ESA Euclid team. In the collaboration I am part of the Weak Lensing the Theory Science Working Groups. I am also the co-lead of the Theory Likelihood group.
Furthermore, I am a core-member and software developer of the InterScience Taskforce Likelihood and Non-Linear, in charge of designing, developing and testing the code for «Cosmological Likelihood for Observables in Euclid» or CLOE. This code is going to be a crucial part of the future analysis pipeline.
Constraining Cosmological models using data
I am an expert in advanced inference techniques to constraint models beyond the Standard Cosmological Model using cosmological data available to the scientific community.
I explore new possibilities of constraining inflationary models beyond the canonical slow-roll inflation scenario. I have focused on studying features in the primordial power spectrum from reductions of the inflaton’s speed of sound and alpha-attractors.
New cosmological observables
I am interested in the cross-correlation of Gravitational Waves (GW) astrophysical events (resolved and unresolved) with galaxy clustering. I have focused on studying what cosmological and astrophysical information can be obtained from the anisotropies of the GW background and in the propagation of GWs.
