My primary research interest lies on the field of high-energy physics, which aims to understand the fundamental constituents of matter and the interactions that govern them. This includes the origin of masses, the nature of dark matter, the possible existence of other particles as predicted by current theories such as supersymmetry, the possible existence of extra-dimensions and other pressing scientific questions of our time.

I have done most of my research using particle accelerators, which collide particles at high energies thus forcing the hand of nature to produce particles that are not apparent in every-day activities. I am, since 2003, a member of the CMS collaboration at the Large Hadron Collider accelerator in Switzerland. That is where we were able to find the Higgs boson with the CMS and ATLAS collaborations in 2012, which is a clear validation of the theory of Electroweak symmetry breaking which is the process that gives mass to fundamental particles. While we measured several properties of the Higgs boson, there are several that have not yet been measured, and deviation from predictions may lead to the discovery of so called "new physics." On such property is the strength of the coupling of the Higgs to muons. To that purpose my team is involved in a search for this property which is expected to have discovery potential by 2026. I am currently also involved in a search for a particle that could explain the discrepancy observed between data and prediction (so call R(D)/R(D*) anomaly) using a model of lepton flavor universality violation.
