Background

Professor Gray is a Senior Researcher at the Centre for Health Services Research within the Faculty of Medicine.

He has formal training in medicine as a specialist geriatrician and in health administration. Previously he held senior management positions in the public health system in Victoria, in general management and aged care services. He joined academia full time at UQ in 2002. He directed the Centre for Health Services Research in its foundational period 2017-22. He now leads a vibrant research program that focuses on system level improvements within aged care.

His research interests focus on aged care policy, models of aged care service delivery, assessment and care planning systems, and in recent years, health informatics and telemedicine strategies.

He leads international development of hospital systems, and is a Board member and the Australian coordinator for interRAI, a multinational research collaborative.

Research impacts

The primary research driver is to improve the quality of healthcare, and life in general, for older people, through the use of new technologies and systems of care. In recent years, this interest has broadened to vulnerable populations at all ages.

Over the course of his career, his research has influenced the design and operation of hospital, community and institutional aged care in Australia. He has contributed to the evolution of telehealth in Queensland and Australia. He has been a major contributor to the development of assessment systems internationally through the interRAI research collaborative, particularly with the hospital sector.
