2014-2017: Bachelor's Degree in Physics at the University of Catania with full marks (110/110 cum laude). Thesis: “Mass generation and deconfinement in pure Yang-Mills theory: a variational study” (arXiv:1803.02335).

Attività di ricerca

Currently doing research on the non-perturbative regime of QCD. The main objective is to formulate a non-ordinary perturbative framework in which – in compliance with the results of lattice QCD – the gluons are allowed to develop a dynamical mass at low energies, while the IR Landau pole of ordinary perturbation theory is prevented from appearing in the running of the strong coupling constant.
