About me

PhD student in theoretical physics. I am interested in theoretical aspects of cosmology both in the early and late universe. More precisely, I am currently working on early universe phase transitions involving dilaton fields, and their implications for axion dark matter as well as their stochastic gravitational wave background signatures. I am also interested in the application of Effective Field Theories (EFTs) in the late universe, where I have contributed to the construction of the renormalization group flow of the galaxy bias parameters within the framework of the EFT of Large Scale Structure in the presence of primordial non Gaussianity.
