Héctor Gil-Marín is an Associate Professor at the Universitat de Barcelona and a researcher at the ICCUB. After obtaining his PhD in Physics from the Universitat de Barcelona in 2012, he held postdoctoral research positions at the Institute of Cosmology and Gravitation (Portsmouth, UK) and as a Lagrange Fellow at the LPNHE (Sorbonne Université, Paris). His work focuses on the large-scale structure of the Universe, specifically using galaxy surveys to probe the nature of Dark Energy and Dark Matter. He has held prestigious fellowships including the Junior Leader ‘la Caixa’ and the Ramón y Cajal Fellowship.

Lines of Research

  • Cosmology with Galaxy Surveys: Lead researcher in the analysis of major spectroscopic surveys, including BOSS, eBOSS, and the ongoing DESI collaboration, for which he held a builder status.

  • Statistical Methodology: Developing advanced statistical tools and information compression techniques to analyse massive 3D galaxy maps.

  • The Dark Sector: Investigating the accelerated expansion of the Universe and the validity of the CDM model using Baryon Acoustic Oscillations (BAO) and Redshift Space Distortions (RSD).

Grants & Awards
