Research interest
I am a fellow of the International Society for Magnetic Resonance in Medicine and have worked on the applications of magnetic resonance imaging (MRI) to neurological and psychological disorders for over 30 years. My work focuses on the development and optimisation of quantitative MRI techniques such as relaxation time measurements, magnetisation transfer and diffusion tensor imaging, which provide numerical results that can be directly compared between individuals and over time. Recently, my interests have centred on extending these approaches to newly developed near-silent acquisition methods. I am heavily involved in supporting PhD students, chairing the committee monitoring Neuroscience students’ progress, and acting as deputy Associate Dean for Doctoral Studies at the IoPPN.
