  A quantitative understanding of neutrino-nucleus interactions is demanded to
achieve precise measurement of neutrino oscillations, and hence the
determination of their masses. In addition, next generation detectors will be
able to detect supernovae neutrinos, which are likely to shed some light on the
open questions on the dynamics of core collapse. In this context, it is crucial
to account for two-body meson-exchange currents along within realistic models
of nuclear dynamics. We summarize our progresses towards the construction of a
consistent framework, based on the Green's function Monte Carlo method, that
can be exploited to accurately describe neutrino interactions with atomic
nuclei in the quasi-elastic sector.
