Two connected bodies of research: current work on the imaging biomarkers of biological age and preventive whole-body MRI, and a sustained programme on the cardio-respiratory health of Aboriginal and Torres Strait Islander Australians — alongside earlier case reports from hospital and regional practice.
A 2025 body of work developing imaging biomarkers of biological age from whole-body MRI — prostate, arterial, vertebral, renal–brain and neuroimaging markers — using AI segmentation and quantification. The research studies were presented at the RANZCR Annual Scientific Meeting 2025, Melbourne; the whole-body MRI overview was an invited presentation at the Japanese Anti-Aging Conference, Osaka.
A multi-year collaboration with the Darwin respiratory research group, building the radiological evidence base for chronic airway disease in Aboriginal and Torres Strait Islander adults — including work to correct the normative reference values that have systematically mis-classified Indigenous lung function.
Selected clinical and interventional case reports from hospital and regional practice.
Conference presentations and manuscripts currently in submission.
Seven of these papers form a single, sustained programme of research on the respiratory health of Aboriginal and Torres Strait Islander Australians. Read the brief on what that work found, and why the reference standards themselves were part of the problem.
