Ultra-cold Fermi gases with tuneable interactions have gathered much interest in the last decade as an excellent tool for the investigation of the BEC-BCS crossover. The Cooper-pairing dynamics and thermalisation in a strongly interacting Fermi gas are not well understood, as the non-equilibrium dynamics upon a quench of the interaction strength 1/kFa are difficult to study both in theory and in experiment. We present our recent measurement results on the dynamics observed in fast changes of the interaction parameter.
