  We give an overview of recent progress into the infrared structure of QCD
based on the gauge/gravity correspondence and light-front quantization, where
the color confining interaction for mesons and baryons is determined by an
underlying superconformal algebraic structure. This new approach to hadron
physics gives remarkable connections and predictions across the entire mass
spectrum of hadrons and also describes the infrared behavior of the strong
coupling. More recently, an extensive study of form factors, polarized and
unpolarized parton distributions and the sea quark contribution to the nucleon
has been carried out by extending the holographic formalism to incorporate the
nonperturbative structure of Veneziano amplitudes. Contribution to the report
