William Giarè, Ph.D.
Hello and welcome to my website!
I'm a theoretical physicist and cosmologist, currently Postdoctoral Researcher at the Department of Physics and Astronomy of the University of Hawaiʻi.
I obtained a PhD in Astrophysics at Sapienza, University of Rome. Subsequently, I held a post-doctoral research fellowship at the INFN Center for Advanced Studies Galileo Galilei Institute for Theoretical Physics and a Research Associate position in Theoretical Cosmology at the University of Sheffield.
My research lies at the interface between theory and data, spanning cosmology, astrophysics, and particle physics. I study how current and future cosmological and astrophysical observations can test well-motivated extensions of fundamental physics beyond the standard cosmological model.
My work combines theoretical modelling, computational and numerical cosmology, and statistical inference. I am particularly interested in Monte Carlo methods for Bayesian parameter estimation, machine-learning approaches to cosmological data analysis, and the development of tools connecting theoretical predictions with observational datasets. This includes numerical codes for the Cosmic Microwave Background, Large-Scale Structure, and emerging multi-messenger probes.
A central theme of my research is the exploration of new physics within and beyond General Relativity and the Standard Model, from the early Universe to dark matter, dark energy, and gravitational waves.
