The ability to combine advanced neuroimaging techniques and genetic information will fundamentally change our understanding of the brain and how it functions in disease. By applying knowledge of genetic information, Imaging Genomics can be used to determine how individual differences in genes contribute to differences in brain structure and function.

Wave 2 Complete

Following the completion of wave 2, the QTAB project is pausing data collection. We hope to recommence data collection in the coming years. Keep an eye out on this website or our Facebook page for updates and published research papers.

Research Directions

Our research is at the interface of cognitive neuroscience and genetics.

The overall aim is to provide new knowledge and understanding of the neurobiological causes of major mental illnesses through the integration of structural and functional imaging, measures of cognition, health and well-being, and behavioural and molecular genetic approaches.
