As a result of our MRFF funding, the CHAANZ has a central team coordinating research activity and driving CHAANZ’s aims in Australia. Our MRFF team is part of the Clinical Research Group in the Heart Research Institute, is affiliated with the University of Sydney and physically located at Royal Prince Alfred Hospital.

Calum Nicholson


National Coordinator

Calum Nicholson is part of the Clinical Research Group at the Heart Research Institute and works as the National Coordinator for the MRFF Funded grant ‘An Australian Study of the Outcomes and Burden of Congenital Heart Disease’, awarded to CHAANZ in July 2020. This grant aims to collect a complete dataset of Congenital Heart Disease patients in the ANZ Congenital Heart Disease Registry and perform a detailed health profile on a smaller subset of those patients. 


Calum’s previous work in the Clinical Research Group involved performing non-invasive investigations into vascular health to detect early signs of atherosclerosis. Before joining HRI, Calum worked with the Sydney Imaging Core Research Facility at The University of Sydney, using small animal imaging techniques to assist in a range of projects related to transplant biology, dental health and gut health.


Calum completed a Master of Health Data Science at UNSW in 2021, where he used geographical information and analysis techniques to assist with service delivery planning for adults with CHD. Calum’s future research interests involve using the ANZ Congenital Heart Disease Registry and Data Linkage to answer questions about health service utilisation and delivery regarding congenital heart disease.

Tanya Badal


Clinical Research Manager


Tanya Badal is the Clinical Research Manager at the Heart Research Institute for the MRFF funded grant ‘An Australian Study of the Outcomes and Burden of Congenital Heart Disease’. This study seeks to profile Australians with CHD to get a clearer picture of how CHD affects patients, carers and the health system. With this knowledge the Clinical Research Group will use Data Linkage to understand health care utilisation and delivery to address current gaps in care plans, healthcare guidelines and contribute to the development of new care strategies for ANZ patients with CHD.  


Tanya’s experience in ‘world first’ cardiac and respiratory studies has refined her interest in whole-of-life care and a patient’s journey through the health system. Her current research interests include defining areas for future research through data linkage and “consumer driven” research to deliver evidence-based healthcare guidelines and strategies.
