My research applies methods from statistical mechanics to problems in condensed matter physics and biophysics.

Much of my work has been in the field of type-II superconductivity, including theoretical approches to problems such as flux-lattice melting, vortex glass structure and correlations, the peak effect, dynamical states in driven disordered flux-line arrays, the surface melting of the flux lattice and models for data from muon-spin rotation experiments.

Some results: the first direct observation of the vortex glass phase (PRL '04), the resolution of a puzzle in muon-spin rotation experiments on flux-line systems (PRL '06), the theory of the surface melting of the vortex lattice (PRL, '06, PRB, '07), a thermodynamically consistent theory for flux-lattice melting (PRB, '07, and earlier work) and peak effect anomalies in type-II superconductors (PRB-RC,'07,PRB,'10).

Older work includes a proposal for a universal phase diagram for weakly disordered superconductors (PRB, '02, MPLB '01, Physica '01, Phase Transitions '02), reentrant melting of vortex lines (PRL, '96), correlations in disordered fluids and the melting of the disordered flux-lattice (PRL, '94), the theory of muon-spin-rotation experiments in disordered superconductors (PRB, '98) and density functional approaches to flux-lattice melting (PRL, '91, PRB, '96).

My current work centres around the phase behaviour of disordered superconductors, relating theoretical models and their predictions to experimental data (PRB, '12), the use of muon-spin-rotation methods to study novel vortex glass phases (PRL '13) and driven disordered periodic media.


I've also been interested in several problems across soft condensed matter, biological physics and statistical mechanics. Some work: the modeling of double stranded DNA with bubbles (PRL, '05, Biophys J '13), active membranes (PRE, '02, EPJE, '09), motor microtubule mixtures (PRE, '04), sheared colloids (PRE,'09), liquid crystal statics and dynamics (PRE '08, PRE '08, PRE '09, JCP '09,JCP '10, Chaos '10) and polymer rings (PRE '08, J. Stat. Phys '08, JSM '10, EPJE '12).

Some of my papers are archived.


Active matter approaches to living systems provide powerful theoretical methods to describe them. Several current collaborations focus on understanding active (molecular motor-driven) intracellular transport. Specific recent interests are: the organization of chromatin (stem cell chromatin fluctuations: Biophys. J '13) and large-scale nuclear architecture. An active matter description of nuclear architecture is discussed in Nucleic Acids Research '14. Read the paper here.
