The efforts to build an extension of the Standard Model of particle physics have been driven in the last few decades by two main agents: the theoretical need for an ultraviolet completion of the model, motivated in particular by the hierarchy between the electroweak and the Planck scale; the phenomenological evidence of new physics phenomena, from neutrino masses to the baryon asymmetry, from the dark matter to the dark energy. My recent research focused on modelling the origin of neutrino masses within the framework of grand unification theories. I derived the consequences of such models for the generation of the baryon asymmetry of the Universe as well as for the phenomenology of flavour physics in the lepton and quark sectors. Besides future precision experiments in the neutrino and flavour sector, we expect a crucial insight into the new theory from the direct exploration of the TeV energy scale at the Large Hadron Collider, which will reveal the physics of electroweak symmetry breaking. I plan to derive the predictions of the previously built models for the TeV scale phenomenology. I will explore the consequences of the observation or absence of low energy supersymmetry on the underlying theory. The otherwise elusive parameters of a particle candidate for dark matter will be predicted within motivated and constrained models for TeV scale physics. The project will benefit from the host Institute expertise in theories of electroweak symmetry breaking and their phenomenology, as well as in cosmology and experimental particle physics. This will nicely complement my expertise in physics beyond the Standard Model, in view of a long-term employment in theoretical physics research.
