I'm a mathematical physicist specialising in applications of differential geometry to elementary particle physics and condensed matter systems.

There are many systems of partial differential equations of interest in theoretical physics which possess soliton solutions. These are smooth, knot-like lumps of energy which are stable against all deformations. Their applications span the length scale, from models of elementary particles, through condensed matter and biophysics to cosmology. Their study is a fascinating challenge involving geometry, topology, analysis and computer simulation.
Often the space of static soliton solutions forms a smooth manifold, called the moduli space, which can be equipped with a natural Riemannian metric. This is true, for example, of the Yang-Mills-Higgs, abelian Higgs and nonlinear sigma models, whose solitons are called respectively monopoles, vortices and lumps. Following a conjecture of N.S. Manton, it is believed that slow soliton dynamics in such systems is well approximated by geodesic motion in the corresponding moduli space. This leads one to study the Riemannian geometry of soliton moduli spaces and exploit this geometry to understand slow soliton dynamics. My own research concentrates on solitons in 2+1 dimensions, in particular, the completeness, volume and curvature properties of moduli spaces of vortices and lumps.
