Research Activities

My 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 350 journal publications in related topics and my h index is currently 41. 

I work closely with a number of other academics at Imperial College including my collaborations with Dr Will Branford on nanostructured artificial spin ice magnetic systems, and Dr Rupert Oulton and Prof Stefan Maier on plasmonics and graphene within Physics as well as a number of other groups across Imperial College, in particular Prof Mary Ryan in the Materials Department and Prof Nick Long in the Chemistry Department. I have strong links to a number of other UK Universities namely Cambridge, Manchester, Lancaster, Surrey and Cardiff. The group is well connected to international groups in Europe, the USA, Brazil and India.

Post doctoral Researchers in the group include Dr Robert Maher (Surface Enhanced Raman Spectroscopy and Raman spectroscopy for Fuel Cells), Dr Karen Yates (Point Contact Spectroscopy of superconductors and magnetic materials), Dr David Boldrin (barocaloric magnetocaloric and thermoelectric materials), Dr Bing Li (graphene transport) and Dr AndyMoskalenko (artificial spin ice). Dr Garry Perkins is a senior researcher in the group.

I co-supervise a number of PhD students including Nicola Black (CASE award with the National Physical Laboratory on non contact graphene sensors), Daan Arroo (Artificial spin ice microstates), Elysia Sharma (magnetotransport in high spin orbit coupled oxides and thermalised artificial spin ice). We look forward to welcoming three new students to the group from Oct 2018. Freya Johnson (Antiperovskite Mn Nitrides for Barocaloric and Spintronics), Kevin Chan (Superconducting spintronics) and Kilian Stenning (Artificial Spin Ice).

A number of PhD students and post doctoral researchers have recently graduated from the group. In particular congratulations go to: Dr Jeremy Turcaud who moved to a post doctoral position in the USA, Dr Stephanie Walton who has taken up a teaching position, Dr Kelly Morrison who moved to a lectureship at Loughborough University, Dr Sam Ladak and Dr Dan Read who moved to lectureship positions at Cardiff University, Dr Julia Lyubina who has taken up a post at Evonik Industries, Dr Andre Pereira who has taken up a faculty position back in Portugal, Dr Irham Usman and Dr Dominic Moseley who both work as a design engineers at Cryogenics Ltd and Dr Adam Gilbertson who is a trainee patent lawyer.
