Eleonora Di Valentino

Dr. Eleonora Di Valentino is a Senior Research Fellow at the University of Sheffield's School of Mathematical and Physical Sciences, specializing in cosmology and fundamental physics. Her research focuses on resolving cosmological tensions, particularly the Hubble constant discrepancy, by exploring dynamical dark energy models, dark matter interactions, and cosmic microwave background (CMB) anomalies. She leads analyses combining cutting-edge datasets like DESI BAO and gravitational wave observations to probe the universe's evolution.

Key research interests include:

• Interacting dark energy models and their observational signatures
• CMB anisotropies and their implications for early universe physics
• Neutrino mass constraints and dark matter thermodynamics
• Modified gravity approaches to cosmological tensions
• Multimessenger cosmology using BAO and gravitational wave data

Her work highlights trends in addressing the Hubble tension via late-time dark sector interactions and non-standard dark matter behavior. She actively contributes to collaborative projects like the CosmoVerse initiative and the Dark Energy Survey (DES).

Dr. Di Valentino's research group affiliation is the Cosmology, Relativity, and Gravitation (CRAG) group, where she develops novel methodologies for cosmological parameter estimation and model testing.
