Research interests
My research interests are in solid mechanics, fluid mechanics, and the mathematics of materials science and soft tissue damage. Of particular interest are the behaviour of fluid filled cracks, phase transformations and the growth of solids, the evolution of mushy layers, porous media flow, foams, non-equilibrium thermodynamics and the thermomechanics of phase boundaries (especially involving finite elasticity). I use mathematical and computational techniques to study these systems.
I am also interested in general in numerical methods for partial differential equations, optimal transportation theory, computational geometry (generalised voronoi diagrams and their applications). I am also interested in rational mechanics and thermodynamics and problems involving differential geometry.
