Initiatives -
TRA’s objectives are to: 1. integrate knowledge translation and exchange in all of TRA’s work, as well as seek to improve the lives of multiple-birth families by undertaking research of particular relevance to them, nurturing community connections, providing evidence-based resources and advocating on their behalf; 2. develop new frontiers in twin methodology with a focus on causation and new-omics technologies and develop new opportunities for twin research by analyzing linked administrative datasets, and large and complex datasets (big data) in Australia and internationally; 3. continue to provide and deliver a comprehensive suite of research support services that optimize the involvement of twins and their families in research of high scientific merit and build the capability and capacity of the twin research workforce through formal education programs and supervision of students and researchers at all stages of career and study development; 4. continue to build and maintain a critical infrastructure of twin research involving twins and their families as part of the twin registry to underpin the above initiatives. ****
