I am a Ramón y Cajal research fellow working at the Centro de Investigaciones Eneréticas Medioambientales y Tecnológicas (CIEMAT), located at Ciudad Universitaria of Madrid. I am a cosmologist, which means I study the Universe as whole: its origin, evolution, content and physics. My field of expertise is the Large-Scale Structure (LSS) of the Universe and cosmological simulations. I study and model how galaxies distribute in space and what information we can extract from galaxy surveys in order to better understand our Universe. Appart from research, I also teach and do outreach.

Here I outline the fields and subfields my research touches on. Go to Research for further details.

Key words:

• Large-Scale Structure
• Cosmological Simulations
• Galaxy Surveys
• Observational Cosmology
• Dark Energy
• Galaxy Formation and Evolution
• Dark Matter
• Inflation

Main interests/expertise:

• Galaxy Clustering (GC)
• Baryonic Accoustic Oscillations (BAO)
• N-Body Simulations
• Fast cosmological simulations
• Primordial Non-Gaussianities (PNG)
• The galaxy - dark matter connection and Halo Occupation Distribution model (HOD)
• HI Instensity Mapping

Other Interests:

• Redshift Space Distortions (RSD)
• Semi-Analytical Models of Galaxy formation
• Hydrodynamical simulations
• Weak Lensing (WL)
• Cross-Correlations, multi-probe and multi-tracers

International Collaborations

Current challenges in cosmology require the coherent effort of the entire community to be addressed. That is why a large portion of nowadays ground-breaking research is performed within large international collaborations, often with hundreds of scientist involved. This is the list of collaborations in which I have been actively involved:

• Dark Energy Survey (DES) I am currently one of the two conveners of the Large Scale Structure (LSS) Science Working Group (SWG), in charge of Galaxy Clustering (GC), while we analyse the final dataset (Year-6 or Y6). The LSS-SWG is in charge of the whole BAO Key Project (KP), of providing the GC products for the 3x2pt (combined GC & WL) KP analysis and of other science projects related to GC such us the study of Primordial Non-Gaussianitties.

• extended Baryonic Oscillation Spectroscopic Survey (eBOSS) / SDSS-IV I performed the Halo Occupation Distribution analysis for Emission Line Galaxies and I was involved in the ELG and general cosmology analsysis. I was also involved in the eBOSSxGBT analysis.

• Euclid. I am currently one of the leads of the “Simulations for Galaxy Clustering” Work Package. Involved in the Simulations and Galaxy clustering SWG.

• Square Kilometer Array (SKA) I studied the viability and methodology of measuring BAO with SKA HI intensity mapping program in presence of observational (foreground and telescop beam) effects.

• Dark Energy Spectroscopic Instrument (DESI). I generate mock catalogue with PNG. I am also involved in the ELG HOD.

• UNIT simulations (UNITsims) I participated in the UNITsim-Galaxies project. I have led the PNG-UNITsim project (abstracts 2021-3; 2022-2; 2022-3; 2023-1).
