Description
Through the calculation of nucleon matrix elements both in
the forward and off-forward kinematics using lattice QCD, a wealth of
information on the structure of the nucleon can be accessed. This
includes the determination of the electromagnetic form factors, the
axial form factors, moments of (generalised) parton distribution
functions and includes the gravitational form factors. Significant
progress has been made in addressing sources of systematic uncertainty
in lattice calculations, with simulations now performed at physical
light quark masses and on fine lattices. Recent highlights will be
presented and the remaining challenges will be discussed.
