*Quasi Parton Distributions and the Gradient Flow*

The direct calculation of nucleon structure from first principles is an 
unsolved challenge for quantum chromodynamics (QCD). In particular, 
Parton distribution functions (PDFs), which capture the longitudinal 
momentum structure of fast-moving nucleons, are defined on the light 
cone and are not directly accessible in Euclidean lattice QCD. I will 
draw together two relatively new ideas, quasi distributions and the 
gradient flow, to demonstrate how these ideas can help circumvent some 
of the issues facing ab initio calculations of PDFs.
