Guillermo Franco Abellán

Dr. Guillermo Franco Abellán is a Postdoctoral researcher at the University of Amsterdam's Faculty of Science, affiliated with the Institute for Theoretical Physics (ITF). His research focuses on cosmology, particle physics, and astrophysics, particularly addressing observational tensions in cosmology, early universe physics, and dark matter models. He employs advanced computational methods for cosmological inference and simulation.

Key research interests include probing cosmological parameters through CMB observations, analyzing dark radiation and dark matter models, and exploring implications of modified gravity theories. His work often intersects with cutting-edge observational facilities like Planck, ACT, and SPT.

Recent publications highlight contributions to resolving the Hubble tension through novel physics models, developing fast sampling techniques for cosmological initial conditions, and investigating the interplay between neutrino physics and cosmological constraints. His interdisciplinary approach spans theoretical frameworks and data-driven analysis.

Abellán collaborates on large-scale projects such as the CosmoVerse initiative, aiming to synthesize multi-messenger data and address fundamental cosmological questions. His work emphasizes rigor in statistical methodologies, including Bayesian inference and machine learning applications.
