This thesis presents first results on jet reconstruction in simulated Pb+Pb collisions using the ALICE detectors and a UAl-based cone jet finding algorithm which has been modified and optimised to reconstruct high-PT jets on an event-by-event basis. Optimisation of the algorithm parameters and methods used to suppress the large background energy contribution while maximising the algorithm efficiency, are discussed and the resulting jet energy and direction resolutions are presented.
