Abstract: In this talk, I will present the current status of neutrino mixing parameters and masses. Since the discovery of oscillations, neutrino oscillation experiments have reached a very good level in precision. Due to correlations among parameters, a global fit combining many different datasets can give more precise results than a single experiment on its own. I will present the results of the latest global fit performed by our group. However, a few experiments have observed anomalous results that could be explained by non-standard neutrino oscillations. Therefore, in the second part of the talk, I will review the current status of neutrino oscillations in the presence of a light sterile neutrino.
