Professional biography

I received my DPhil in theoretical physics from the University of Oxford before moving to the U.S., where I worked at the University of Virginia and Brookhaven National Laboratory. I then returned to the UK to take up an EPSRC postdoctoral fellowship at UCL, before becoming a lecturer at the OU.

Research interests

My research area is theoretical condensed matter physics, particularly systems that exhibit exotic behaviour due to strong correlations or quantum fluctuations. My work includes subjects in quantum magnetism, high temperature superconductors, low dimensional systems (quantum chains, wires and quasi-2D systems), many-body entanglement and cold atomic gases. I seek to understand these unconventional quantum systems, and to develop the necessary tools to do so. I use both analytical and numerical methods and often collaborate with experimentalists.

I have developed open source code to study 2D many-body quantum systems, realised as large arrays of coupled quantum chains. This has proved particularly useful for studying out-of-equilibrium dynamics (time dependent behaviour) in such systems. A technical talk I gave on some of this work is available to view here.
