Research interests

My research focuses on understanding the behavior of complex fluids from a microscopic perspective using the tools of statistical mechanics and computer simulation. The questions I am interested in range from the fundamental, e.g. how do viscous liquids flow, to the applied, e.g. how to make nanocrystals assemble into structures that will be useful for harnessing solar energy. Common themes are a fascination with beautiful structures that can appear spontaneously in systems driven by disorder, and materials that have both liquid-like and solid-like properties. To inspire this work and to stimulate research on real physical systems I like to work closely with experimentalists.

My current research interests include:

  • Self-assembly of nanorods and nano-polyhedra
  • New materials for plasmonics and solar energy harvesting
  • Glass-formation, nucleation and crystal growth
  • Structure and dynamics of soft condensed matter
  • New Monte Carlo and molecular dynamics methods
