Principal research interests and expertise

My research focusses on questions relating to the mathematics of solid materials, and principally on crystals. Crystals are made up of atoms laid out in a regular repeating pattern, and include most metals at room temperature and pressure.

I am particularly interested in modelling defects and microstructure of these materials, i.e. the behaviour of small-scale phenomena which affect material properties of crystals on much larger scales. Defects are known to play an important role in the behaviour of plastic (or irreversible) deformation of crystals, and ultimately govern their failure. Deriving and improving predictive models for the evolution of microstructure therefore has important potential consequences for engineering applications.

Some research topics I have worked on in the past include:

  • Micromechanics of materials:
    • Crystalline defects, especially dislocations and their evolution
    • Thermodynamics limits: linking microscopic and macroscopic properties of solids
    • Metastability and temperature-driven evolution of defects
  • Asymptotic methods in the Calculus of Variations, PDE and Stochastic Analysis:
    • Gamma-convergence techniques
    • Stochastic Homogenization
    • Large Deviations Theory
