description: In this thesis the Monte Carlo generator JEWEL (Jet Evolution With Energy Loss) is presented. It interleaves the perturbative final state parton shower evolution with medium interactions occurring in ultra-relativistic nuclear collisions. It contains a microscopic model of elastic scattering so that the probability for scattering can be compared to the splitting probability in each step during the evolution. Radiative processes are included in a schematic way by increasing the splitting probability. The perturbative parton shower is interfaced with a string hadronisation model that is suited also for jets in a nuclear environment. In the absence of medium effects JEWEL reproduces important benchmark measurements in e+ + e- collisions. In the medium the modifications of jet characteristics due to collisional and radiative energy loss as well as the jet-induced modifications of the medium are characterised. A set of jet observables that should allow to discriminate between elastic and radiative energy loss is identified. Broadening of jets due to energy loss is sensitive to hadronisation, but generally very little broadening is observed in JEWEL. Finally, further developments of the model are outlined. This includes the geometry and expansion of the medium and a microscopic model of inelastic scattering. Furthermore, a prescription how to include the suppression of induced gluon radiation due to an interference phenomenon (LPM effect) in a Monte Carlo model is presented.
