At the fundamental level, core-collapse supernovae are gravity-powered neutrino bombs: neutrinos carry most of the energy and dictate every aspect of the explosion dynamics. In particular, they set the physical conditions in the hot bubble surrounding the protoneutron star, where certain proton-rich heavy isotopes, whose origins have been an enduring mystery, could be synthesized. I will discuss the results of self-consistent calculations of neutrino-driven outflows which can successfully reproduce the patterns of p-nuclei observed in the solar system. Neutrino flavor oscillations will be seen to play several important roles. They can imprint information about the physical conditions in the hot bubble on the neutrino signal that can be measured at DUNE. They can also affect the conditions in the neutrino-driven outflow and the resulting nucleosynthetic yields. To make the talk accessible at a broader audience, several key results in neutrino physics, supernova dynamics, and nucleosynthesis will be introduced along the way.
