Dr Renée O’Donnell is an Early Career Research Fellow at the Health and Social Care Unit. Dr O’Donnell is an expert in program implementation, evaluation and scale-up of community-based services. In particular, Dr O’Donnell is presently leading the implementation of two state-wide programs which support marginalised groups in the community (i.e., persons from low socioeconomic backgrounds and persons with lived experience of out of home care) to improve their health and wellbeing. As part of this body of work, Dr O’Donnell is identifying and addressing the barriers which impede upon the implementation of these community-based programs.
