Professional/research interests:
My expertise is in mathematical models and developing code for both acoustic and elastic waves interacting with complex solids and liquids. I am particularly interested in using acoustic and elastic waves to:
- characterise particulate materials (emulsions, suspensions, powders, composites). I model both backscattering/reflection and transmission in these materials. I am leading expert in modelling waves in densely pack particles (high concentration) and using a broad frequency range.
- measure stress and anisotropy in solids. I am currently working on developing methods to measure stress in metals by using ultrasonic waves.

Read the below for a non-technical overview of my research :

We still do not fully understand how waves (like sound, radio, light, and vibrations) behave in many materials. How well can these waves propagate, and how much information can they carry in different materials?

Answering these questions will allows us to design the next generation of materials that can control waves. These new materials can then improve telecommunications by controlling light and elastic waves, and mechanical engineering by controlling vibrations and even earthquakes!

The main way we sense the world around us is by using waves too. Light and sound are reflected from all materials, and when they reach us, our brains can decode them to understand what objects are around us.

In a similar way, waves are used to sense materials during manufacturing. To automate manufacturing, we need to develop sensors that can decode waves like our brains do. Ideally these sensors would be able to detect changes in the material's microstructure, and as a result determine when the material has reached its ideal flexibility, strength, and capacity to transmit information!

What would you like UKAN to do for you?
