Research interests

Real crystals stop somewhere; where and how they stop often determines their behaviour, how they nucleate and grow. A spectacular example of controlling crystallisation is the ability of living systems to grow minerals in complex shapes and sometimes unusual phases. The bulk properties of crystals, particularly transport properties, are often determined by point defects. These can be intrinsic, produced by doping, induced by exposure to radiation and so on. Understanding the behaviour of defects, interfaces and how they control crystal properties needs well-directed simulations in conjunction with state-of-the-art experiments. We therefore collaborate closely with experimental groups, using methods including: static lattice calculations, molecular dynamics, kinetic Monte Carlo, quantum mechanics, mesoscale and finite element simulations.

Key research interests:

  • Nucleation and crystallisation (including biomineralisation)
  • Modelling electroceramic materials
  • Radiation damage in host materials for nuclear waste
  • Geochemistry (particularly trace element partitioning)
  • Simulation methods; particularly defects, interfaces and rare events
