  The Matter-Neutrino Resonance (MNR) phenomenon has the potential to
significantly alter the flavor content of neutrinos emitted from compact object
mergers. We present the first calculations of MNR transitions using neutrino
self interaction potentials and matter potentials generated selfconsistently
from a dynamical model of a three-dimensional neutron star merger. In the
context of the single angle approximation, we find that Symmetric and Standard
MNR transitions occur in both normal and inverted hierarchy scenarios. We
examine the spatial regions above the merger remnant where propagating
neutrinos will encounter the matter neutrino resonance and find that a
significant fraction of the neutrinos are likely to undergo MNR transitions.
