Understanding the QCD structure of the nucleon and nuclei is of fundamental importance in sub-atomic physics. A major focus of research on this topic is the partonic structure of the nucleon, including its spin structure. In this talk, I will review recent advances and progress, and emphasize the opportunities with continuing projects at RHIC at Brookhaven National Lab, CEBAF at Jefferson Lab, and the planed electron-ion collider (EIC). In particular, the EIC will provide unprecedented precision in exploring many of the outstanding questions. The talk will focus on one particular aspect: nucleon tomography, a three-dimension imaging of partons in the nucleon.
