<b>Overview of hadron structure from Lattice QCD</b><br>
</div>
<br>
Understanding hadron structure from first principles is
considered a milestone of hadron physics and numerous
experiments have been devoted to its study, starting with the
measurements of the electromagnetic form factors more than 50
years ago. Lattice QCD (LQCD) is a powerful approach for the ab
inition calculation of hadron observables.<br>
Emerging results form LQCD are providing input to phenomenology,
as well as, to Physics beyond the Standard Model. This is due to
the impressive progress in the simulation of LQCD mainly due to
improvements in the algorithms, development of new techniques
and increase in computational power, that have enabled
simulations to be carried out at parameters very close to their
physical values. In this talk we will review results obtained
with simulations at or near to the physical value of the pion
mass, such as he nucleon axial charge and the first moments
parton distributions, for both the valence and sea quark
contributions, and discuss their implications on the spin
content of the nucleon. Selected results on the electromagnetic
form factors and radii, the quark content of the nucleon and on
the neutron electric dipole moment are also discussed. <br>
