At ISIS I am jointly responsible for the MAPS direct geometry chopper spectrometer, and am project scientist for the guide and disk chopper upgrades. I am also coordinating a project to upgrade some of the components of the ALF alignment diffractometer.
In addition, I have a strong involvement in the development of software for analysis and visualisation of data from time-of-flight chopper spectrometers in the excitations group. The main project on which I work is the Horace suite of programs. These are used to analyse large datasets that are generated when multiple measurements of the scattering from a single crystal in slightly different orientations are made. This technique has now become standard at many facilities around the world. In addition I am involved with advising the Mantid project, specifically on the VATES toolkit for data visualisation and analysis.

Scientifically, I am interested in high-temperature superconductivity, especially that found in the cuprates and iron-pnictides. My work on the former has focussed on understanding the nature of so-called "stripe order", whereas on the latter we have been working on understanding the relationship between spin fluctuations and superconductivity. See the following papers for details:
I have also worked extensively on strongly correlated manganese oxide compounds, in particular multiferroic materials, i.e. materials which display coupling between magnetic and electric properties. I have used neutron and x-ray resonant scattering in order to understand the complex magnetic order of materials which can contain magnetic rare earth as well as magnetic transition metal atoms.
