Current Research

Carries out research in the mechanics of crystals. The continuum theory of defective crystals is ripe for development. Recent research has shown how mechanisms of plastic flow emerge naturally from geometrical ideas to do with the microscopic structure of the crystals. It turns out that there is a connection between the structure of crystals with constant dislocation density and the theory of Lie groups, and this observation offers exciting prospects for the cross fertilisation of mathematics and mechanics.
