Research Interest
Throughout my PhD and Post-Doc at the University of Nottingham I specialised in investigating pathways for human metabolism using in vivo Magnetic Resonance Spectroscopy (MRS) and my main research interests lie in using multi-nuclear MRS, particularly 1H, 13C and 31P nuclei, in combination with other MRI techniques (ASL, fMRI, T2*mapping and DTI), to gain further insight into healthy human metabolism, as well as to understand how metabolism is perturbed in pathologies including diabetes, non-alcoholic fatty liver disease, myopathies, psychiatric and neurodegenerative diseases.
