I will briefly introduce the theory of Transverse Momentum Dependent Parton Distributions (TMD), which describe the three-dimensional structure of the nucleon in the momentum space and get access to the correlations of spin and orbital angular momentum. For the remainder of my talk, I will focus on how to experimentally study TMD by using the Semi-Inclusive Deep Inelastic Scattering (SIDIS) and the Drell-Yan (DY) processes. Following a short explanation of using SIDIS to study TMD, I will summarize the existing experimental results, discuss the planned Jefferson Lab 12GeV experiments [mainly the SIDIS program on Solenoidal Larger Intensity Device (SoLID) in Hall-A], and discuss studying TMD on the future Electron Ion Collider (EIC). In addition, I will discuss TMD measurement via the DY and introduce the ongoing and planned DY programs at Fermilab, COMPASS, and other facilities. I will end my talk with a discussion of the medium modification effect on nuclear TMD and propose some future experimental techniques to investigate such a novel effect.
