I will discuss the status and future of numerical lattice Quantum Chromodynamics (QCD) calculations of nuclear matrix elements. The goal of the program is to provide a description of nuclear structure directly from the fundamental quark and gluon degrees of freedom of the Standard Model. I will describe recent studies of nuclear observables such as double-beta decay matrix elements, nuclear corrections to axial matrix elements relevant to long-baseline neutrino experiments, and nuclear sigma terms needed for theory predictions of dark matter cross-sections at underground detectors. I will discuss the progress and challenges on these fronts, and also address recent work constraining `exotic glue’ and nuclear gluon effects in nuclei, both of which will be measurable for the first time at a future electron-ion collider.
