DESCRIPTION:In this talk I will give an introduction to the solution of th
 e spectral problem 1D defect CFT living on the supersymmetric Wilson Line 
 in N=4 Super-Yang-Mills theory. First\, I will review the descriptions of 
 the theory on both sides of the AdS/CFT correspondence\, and how one can g
 o about enumerating states in either setup. Then\, since the insertion of 
 the line defect preserves the integrability structure\, I will briefly des
 cribe how one can adapt integrability-based methods originally developed t
 o compute the spectrum of local operators in N=4 Super-Yang-Mills theory t
 o the spectral problem of the defect CFT\, before displaying the non-pertu
 rbative low-lying spectrum certain subsectors of the theory. Lastly\, by f
 ocussing on "two-particle" states in the theory\, I will propose a simple 
 map from the letters that capture the degrees of freedom on the gauge theo
 ry side\, to the letters capturing degrees of freedom on the string theory
  side. This map immediately predicts a particular behaviour of the spectra
 l data\, which can be checked against existing integrability based results
