As the Senior Technical Officer for the Neuroscience of Addiction and Mental Health Program, I drive advanced MRI data analyses from longitudinal datasets and consortia. This includes analysing, interpreting, and visualizing diffusion MRI data from various consortia. In addition, I provide technical and analytical support to Ph.D. and Master students in their respective projects.

I completed my MPhil at the University of Melbourne in 2020. My MPhil focussed on characterising white matter asymmetry in a healthy human brain using Diffusion MRI. I have >6 years of research experience in the field of MRI includes performing data analysis and visualization in diffusion MRI using state-of-the-art diffusion methodologies.
