The quest for the ultimate theory which would unify all known forces of the Universe into a unique force is one of the most ambitious and challenging enterprises of the mankind. In the mean time, we thrive to understand Nature with the theoretical and experimental tools available.
The recent observations of neutrino oscillations lead to masses assigned to the different neutrino flavours. These observations are the most outstanding ones to date in this decade, with important implications on the way we perceive the Universe from elementary particle physics to cosmological scales. Face these observations, the Standard Model of Particle Physics has to be modified to accomodate masses for the neutrinos. It might also has implications in supersymmetric models. Supersymmetric particles like neutralinos are, on the other hand, candidates for cold dark matter. The observation of these particles, and the measurement of their cross-section, can be used in the framework of the minimal Supergravity (mSUGRA) model to compute the relic density of the Universe. This density can be compared to that measured using the Cosmic Microwave Background (CMBR) such that the contribution of the supersymmetric particles to the overall cold dark matter can be evaluated.
The connection between particle physics and cosmology is the focus of my current research interest. For this purpose, I have been contributing to the R&D of the T2K and ILC experiments with intention of performing physics analyses with the data collected by these detectors.
I obtained my Ph.D. degree working at CERN on the DELPHI Collaboration (LEP). I was responsible for the hardware implementation and tests of the Synchroton Radiation Detector (SRD). My thesis consisted also of physics analysis to measure the Michel parameters.
