I am in the Condensed Matter and Materials Physics group (CMMP) group in the Department of Physics and Astronomy at University College London. I am a Principle Investigator in the new London Centre for Nanotechnology (LCN).
My current research involves several techniques including electrical transport in high magnetic fields at temperatures between 300mK and 300K, and SQUID magnetometry. My research interests (Research) mainly concern magnetically ordered and strongly correlated electron systems. The materials in which I am exploring these ordered states range from electron lattices in solid metal ammonia compounds (for example Li(NH3)4) to superconductivity in graphite intercalation compounds (C6Yb and C6Ca). In addition I use X-ray synchrotron and neutron scattering facilities.

I studied part time for my BSc in Physics at Birkbeck College and graduated in 1987. I remained at Birkbeck (1987-97) where I undertook a PhD in Experimental Physics part time whilst working in the department and was awarded my doctorate in 1995. In 1997 the Birkbeck Physics department was closed and I moved to UCL joining the Condensed Matter group within the Physics Department where I worked as an Experimental Officer. In 2007 I was appointed to a lectureship in the Department of Physics at UCL.
My thesis work focused on the study of transport and magnetic properties of rare earths. In parallel to this I developed an interest in heavy-fermion materials such as UCu5. Since moving to UCL my research has broadened to the study of electron states in a variety of materials both liquid and solid; the purpose being to explore the impact of dimensionality on the collective ground states of electrons. Amongst these materials was the exciting discovery of superconductivity in the calcium-graphite intercalation compound C6Ca, which pushed the transition temperature for this class of compounds up by approximately 2 orders of magnitude. This discovery forms one of several different avenues being explored in the field of graphite/graphene physics.
