A high-luminosity electron ion collider (EIC) is highly anticipated in the United States, and would give an unprecedented opportunity to perform tomographic imaging of protons and nuclei alike. A partonic tomography of nuclei in particular would present novel opportunities for observing how QCD manifests within conventional nuclear structure, e.g., it would provide information on the spatial correlations between the quarks and gluons in nuclei, and reveal medium modifications in multidimensional partonic distributions including GPDs and TMDs. This workshop will explore what aspects of QCD in particular can manifest in nuclei at an EIC, what measurements would be sensitive to these manifestations, and what design parameters are needed to make such measurements possible.
