Current Research

My research currently focuses on ultrasonic techniques for non-destructive testing applications in solid materials, and for physical property measurement in fluid systems. I am particularly interested in the propagation and scattering of sound in multi-phase systems, whether cavities in solid material, or suspended particles in a fluid, or any other combination of materials. With a background in the physical sciences, the main aim of my work has been in the prediction of the scattering behaviour of dispersed systems, and in the development of improved mathematical and numerical models for scattering. The application of ultrasonics to biological systems, such as protein solutions, is also an area of interest.

Earlier work has included computer modelling of creaming and flocculation in emulsions, and of chocolate flow under vibration.

Future Research

Work on ultrasonic scattering will continue, and applications for ultrasonic measurements to probe system properties are continually under development. I am keen to develop interdisciplinary research interests, which bridge traditional research techniques and approaches in order to maximise the research benefit.
