We will discuss the one-loop anomalous dimensions of Super Yang-Mills operators dual to open strings ending on AdS giant gravitons (AGG) and describe the spin chain description of gauge theory operators. A semi-classical analysis of the Hamiltonian describing the anomalous dimensions of AGG operators will allow us to give a geometrical (stringy) interpretation for the gauge theory parameters. This same analysis will also show evidence for the existence of continuous bands in the Hamiltonian spectrum.
