Cavitation (ultrasonically driven bubble activity) has a variety of applications in the medical and industrial sectors. However, there is currently no framework for the measurement and reporting of cavitation which means that the scientific literature is inconsistent, and it is difficult to compare studies from different groups. Current issues include metrics, such as the mechanical index, that are being used beyond their limitations and a lack of a proper classification system means that cavitation is often categorised as either stable or inertial with little scientific reasoning.

The aim of my project is to develop a scientifically grounded framework that will tackle these issues and will allow for meaningful comparison between similar studies over a range of medical and industrial applications. To do this, I will study many types of cavitation in experiments that are representative of the applications. High-speed imaging with parallel acoustic monitoring will help determine a fundamental understanding of the acoustic cavitation signal, which will allow for the critical analysis of current practices and propose new ones.

In partnership with Precision Acoustics Ltd, I hope to share my findings with the British Standards Institute (BSI) committee on ultrasonics and contribute to international standards that will ensure more consistency in cavitation research.
