  In these proceedings we report recent progress on understanding hadron and
jet production in electron-nucleus collisions at the future Electron-Ion
Collider [1,2]. These processes will play an essential role in the exploration
of the partonic structure of nuclei and the study of parton shower evolution in
strongly-interacting matter. We employ the framework of soft-collinear
effective theory, generalized to include in-medium interactions, to present the
first theoretical results for inclusive hadron and jet cross sections, as well
as the jet charge modification in deep inelastic scattering on nuclei. We
further demonstrate how to separate initial-state and final-state effects.
