Research Interests

My PhD was focussed on understanding the use of quantitative MRI for the study of
de- and remyelination in multiple sclerosis (MS). Now, I am interested in expanding
my scope of quantitative MRI techniques, use 7T for in-depth study of MS pathology,
and develop new tools in order to optimise the use of MRI for studying the brain.
