My research interests lie in the application of continuum mechanics to physiological and industrial problems. In particular I am interested in problems involving interaction between a fluid flow and deformable interfaces, such as liquid-gas free surfaces and elastic solids.
My current research focuses on modelling flow of CSF and blood in the human eye and along the optic nerve. Recently completed projects include an investigation into the onset of large amplitude pulsations in the retinal vein at the optic disc (the retinal venous pulse) where we demonstrated how observation of this pulse might be used to estimate intracranial pressure non-invasively.
I am also keenly interested in the dynamics and fracture of gas-liquid foams, with application to the production of high-porosity metallic solids (solid metal foams) as lightweight materials.
