Research Interests

My research interests are in the general area of computational statistical mechanics.  

For my DPhil (PhD), I studied the equilibrium dynamics of two simple systems that are ubiquitous in plasma physics.  This involved a detailed comparison of the results of molecular dynamics simulations with analytical models of the physical properties of these systems. The full story is in my DPhil thesis, available below.

In my current role, I am studying nucleation of crystal phases.  Nucleation, which is the first stage of crystallisation, is a problem in non-equilibrium statistical mechanics.  This already makes understanding nucleation rather tricky.  To complicate things even further, since nucleation involves overcoming an energy barrier, it is a 'rare event', and therefore difficult to observe directly in computer simulations.  This has led to the development of advanced simulation methods.  In my research, I use these methods to study nucleation in simple systems.
