Health and Wellbeing Centre for Research Innovation
We currently have opportunities available for multiple higher degree research (HDR) students to join the Health and Wellbeing Centre for Research Innovation (HWCRI). In 2022, UQ received foundation funding from Health and Wellbeing Queensland (HWQld) to co-fund the creation of the Health and Wellbeing Centre for Research Innovation (HWCRI). In partnership with HWQld, HWCRI provides clinical and research expertise in in the fields of physical activity and nutrition with a population and preventative health focus, to inform HWQld’s program design, delivery and evaluation. HWCRI conducts innovative and novel high impact transdisciplinary research in community health and wellbeing across the lifecourse, to reduce health inequities and improve the health and wellbeing of all Queenslanders. The UQ HWCRI aims to translate research and evaluation findings into concepts and products for population level, state-wide implementation; and to build and sustain capacity in health promotion expertise by providing ‘real world’ training opportunities for undergraduate, post-graduate and higher degree research (HDR) students and fellows.
Successful applicants will be part of the School of Human Movement and Nutrition Sciences which is consistently ranked in the world’s Top 5 and is highly regarded nationally and internationally for its teaching, research and community outreach programs. The 2021 QS World Rankings by subject area ranked UQ first in Australia and second in the world in sports-related subjects. They will also be supported and conduct research in partnership with Health and Wellbeing Queensland (HWQld) which is a Queensland Government prevention agency aimed at improving population health and reducing health inequities by reducing the burden of chronic disease across the state. The health and wellbeing of the next generation of Queensland children is a key focus for HWQld and offers a once in a life-time opportunity to change the lives of the next generation where every Queenslander can live their best life, regardless of where they live.
This opportunity would suit students with a background in allied health, health promotion, public health, health psychology, implementation science, or human movement studies. Excellent communication and interpersonal skills are essential. Experience working with industry stakeholders and knowledge of qualitative and quantitative research methods and behaviour change would be of benefit. First Nations applicants are particularly encouraged to apply. This is a unique opportunity to be at the forefront of this exciting new research centre and engage with industry partners and government and specific programs of research can be tailored based on the applicant’s interest and previous experience and expertise.
