My research interests include the study of magnetic materials (for solid state magnetic cooling using magnetocalorics) and highly spin polarised magnetic materials (for spintronics and long range spin triplet superconductivity) as well as an interest in transport properties of high mobility materials such as narrow gap semiconductors and graphene, superconductors (in particular gap structure and vortex pinning), and Raman spectroscopy (surface enhanced Raman spectroscopy and Raman spectroscopy as a tool to understand Fuel Cell materials). I have published over 400 journal publications in related topics and my h index is currently 47.
I work closely with a number of other academics at Imperial College as well as strong links to a number of other UK Universities namely Cambridge, Glasgow, Manchester, Lancaster, Surrey and Cardiff. The group is also well connected to international groups in Europe, the USA, Brazil and India.
I co-supervise a number of PhD students including Matthew Hamer (CASE award with the National Physical Laboratory on non contact graphene sensors),Freya Johnson (Antiperovskite Mn Nitrides for Barocaloric application and Spintronics CASE award with Hitachi Cambridge), Kevin Chan (Superconducting spintronics - CDT ACM) and Kilian Stenning (Artificial Spin Ice).
