In the latest years a cumulative evidence for a new phenomena in particle physics called neutrino oscillation appears and culminate with the Nobel Prize in physics in 2015 for T. Kajita and A. McDonald for the experimental discovery of neutrino oscillation. At the present there are an intense effort in Brazil and other countries to explore this new frontier and try to elucidate the implications of this phenomena for particle physics. In this talk I will describe the current status and the very interesting topics that we are pursuing to elucidate from the theoretical and experimental point of view.
