Pathway Journey

Characterising structural and functional brain changes associated with healthy ageing using longitudinal MRI in rats.


My PhD research as part of the MRC DTP used MRI to identify changes in brain networks related to healthy ageing. During this time, I realised my enthusiasm for solving data analysis problems and developing resources for image processing and analysis. In particular, I am interested in extending processing tools designed for human data to be species agnostic, and supporting open science and reproducibility in the preclinical MRI community. I continue to apply network-based analysis methods to MRI data, as I learned during my time in the DTP, with the aim of modelling brain changes over time.
