In this paper, two important transport observables in the relativistic heavy ion collider (RHIC) experiment-damping rate and jet quenching parameter-are calculated from an AdS/QCD model. A quark moving in the viscous medium such as the quark-gluon-plasma is modeled by an open string whose end point travels on the boundary of a deformed AdS5 black hole. The correction introduced via the deformed AdS5 is believed to help us better understand the data which is expected to be measured in the RHIC.
