MOSAICS, led by the partnership between Cochlear Ltd., leader in implantable hearing solutions, and the Radboud Medical Centre, world-class centre for auditory research, is a European Industrial Doctorate that has now ended. Four early-career researchers (ESRs) were trained within MOSAICS, with the joint aim to minimise outcome spread and maximise societal participation for Cochlear Implant (CI) users, through the investigation of objective measures, neurocognitive measures, societal impact, and fitting of CIs.
