Heavy quark production and attenuation will provide unique tomographic probes of QCD matter created in Ultrarelativistic Heavy Ion Collisions. In this talk I will present the radiative energy loss mechanisms that we developed [1,2], as well as the heavy flavor suppression results obtained from this energy loss [3]. Surprisingly, recent data on nonphotonic electron quenching in central Au+Au collisions at 200 AGeV at RHIC show significant discrepancies with theoretical predictions that are based only on the radiative energy loss mechanisms. However, our recent study [4], indicates that the inclusion of elastic energy loss in the jet quenching may help to solve this puzzle. The ongoing work on the rigorous inclusion of the elastic energy loss into the existing radiative energy loss formalism will also be discussed.
