Background

I am a Research Fellow at the University of Queensland with over 9 years of experience in neuroimaging research. I specialize in developing analysis pipelines for multimodal imaging data (diffusion MRI, fMRI, structural MRI), with applications in substance use, mental health, and neurological disorders. I currently lead projects that integrate advanced imaging techniques with high-performance computing to deliver scalable solutions.

What I do

  • Design and deploy automated MRI workflows that scale

  • Mentor students and junior staff in neuroimaging methods and coding

  • Build analysis scripts with clear provenance for clinical and mental-health applications

Expertise

  • Multimodal MRI: diffusion (FBA, DTI), fMRI, structural MRI; experience with 7T data

  • Pipeline engineering: BIDS conversion, QC automation, longitudinal handling

  • Methods: IVIM modelling, tractography, cohort-level analytics

Toolbox

  • MRtrix3, FSL, FreeSurfer, SPM, AFNI, CONN, DIPY, fMRIPrep, Nilearn

  • Python, Bash, C++; MATLAB, R, SPSS; GraphPad Prism

Keywords

  • Diffusion MRI, fMRI, structural MRI

  • Fixel-Based Analysis, DTI, IVIM

  • Data harmonisation, quality control, BIDS, HPC

  • Substance use, mental health, neurological disorders

Qualifications

  • Masters (Research) of Neuroscience, University of Melbourne

Research interests

  • Scalable, Reproducible MRI Pipelines (BIDS → HPC → XNAT)

    I build container-first workflows that transform diffusion, structural, and functional MRI into clean, analysis-ready datasets with full provenance. This includes BIDS conversion, automated QC, data harmonisation, and SLURM-based orchestration on Bunya HPC with XNAT integration

  • Diffusion MRI Methods and Microstructure Biomarkers

    My focus is on FBA, DTI, tractography, and Free-Water/IVIM modelling to derive robust microstructural markers across sites and scanners. I’m also developing AI-assisted denoising for diffusion MRI to stabilise downstream metrics.
