Dr Griffiths is a Senior Research Fellow and leader of the neurodevelopmental and eating disorders neuroimaging team within the Brain Dynamics Centre.
Kristi completed her PhD in behavioural neuroscience at the University of Sydney. She was subsequently awarded a Tenix Foundation Postdoctoral Fellowship, followed by a NHMRC Early Career Fellowship. She completed neuroimaging training with the fMRI Visiting Fellowship at the Martinos Center for Biomedical Imaging in Boston.
Kristi has published more than 40 peer-reviewed papers, which have been highly cited (1000+), and she has secured >1.3 million dollars in competitive research funding. She is a peer reviewer for top international journals and has served as reviewer for international grant funding bodies (e.g. Agency for Health Quality and Assessment of Catalonia).

Research Focus

Her research is dedicated to applying neuroimaging methods to better understand neurodevelopmental and psychiatric disorders in young people, with the ultimate goal of advancing personalised medicine. Dr Griffiths’ work recognises the heterogeneity commonly seen within psychiatric disorders, and has employed transdiagnostic data-driven approaches and “bio-typing” to find markers that can predict response to various treatments. Her research program applies connectivity analyses across a range of imaging modalities, including resting-state fMRI, fMRI and diffusion-weighted imaging. This research has been undertaken across a range of disorders affecting youth, including ADHD, depression, bipolar disorder and eating disorders.
