I am interested in the theory and phenomenology of the SMEFT in the top sector. In particular, I am searching for interference sensitive observables in four top quarks production process.

I am currently working on light hidden sector Dark Matter (including sterile neutrinos and ALPs). The main focus of this work lies on the Dark Matter production in the early universe, in particular on the computation of thermal corrections to the product during freeze-in. I want to make more reliable predictions for the relic density in such models, which can be tested in experiments.

My current work consist in the automation of the one-loop renormalization of the electroweak sector in the SMEFT. I am also interested in gauge invariance in both the SM and GR and in non-local effects.

My research is currently focused on spatial phase separation occurring in some statistical models. This phenomenon appears when boundary conditions induce macroscopic effects on the system, resulting in the formation of several regions with distinct behaviours. These regions are separated by interfaces generally referred to as « arctic curves ».

PhD Student

Working on potential explanations for the origin of Baryonic and Dark matter. I focus on extensions of the Standard Model with « light » particles, e.g. particles having a mass at the MeV to TeV scale for which thermal corrections are crucial.

I’m working on trajectories of charged particles in electromagnetic knots in vacuum. The next step is to translate these electromagnetic knots into gravitational knots to understand the discrepancy between the theoretical and the observed velocity curves of galaxies.
