Network Neuroscience

The brain is an extraordinarily complex network, comprising billions of cells connected by trillions of synapses.

We use tools from network science and complex systems theory to understand the brain, focusing on:

  • Developing new methods for mapping brain connectivity using non-invasive brain imaging and other techniques;
  • Understanding how genes influence brain network architecture;
  • Identifying principles of brain network organization and development, based on mathematical models; and
  • Characterising how changes in brain connectivity give rise to individual differences in behaviour, and risk for psychiatric and neurological disease.

Capability Lead

Prof Alex Fornito


Prof Alex Fornito completed his Clinical Masters (Neuropsychology) and PhD in 2007 in the Departments of Psychiatry and Psychology at The University of Melbourne before undertaking Post-Doctoral training in the Department of Psychiatry at the University of Cambridge, UK, under the auspices of an NHMRC Training Fellowship. In 2013, Alex assumed his current position in the Turner Institute for Brain and Mental Health. Alex is Co-Director of the Brain and Mental Health Research Hub and Heads the Brain research division.

Alex’s research concentrates on developing new imaging techniques for mapping human brain connectivity and applying these methods to shed light on brain function in health and disease. A major emphasis of his work concerns understanding foundational principles of brain organisation and their genetic basis; characterising brain connectivity disturbances in psychiatric disorders such as schizophrenia; and mapping how brain networks dynamically reconfigure in response to changing task demands.
