Research interests

My general research interests revolve around the use of NMR imaging and relaxometry to investigate the structure and morphology of multi-phase systems, such as polymers, porous and biological media, as well as developing numerical models to simulate their dynamic behaviour at nano- and microscopical levels.

Currently I am focussing on developing experimental strategies for NMR and MRI of biological media using SABRE, particularly on pulse sequence optimization and developement for in-vivo investigations.
