Professor Timothy Leighton FREng FRS


Elected: 2014


Timothy Leighton is a physicist and inventor whose motivation stems from a deep interest in the acoustical physics of bubbles. Through his research, Timothy has made notable contributions to diverse fields in industry, medicine, oceanography and the environment.

Taking inspiration from the way that dolphins hunt fish using bubble nets, Timothy developed the first sonar technique capable of detecting targets in bubbly conditions, such as those near the shore. His medical devices — a tool for monitoring kidney stone dispersal and a needle-free injection system — exploit his in-depth understanding of ultrasound and the collapse of bubbles, respectively.

In 2011, Timothy was awarded the Royal Society Brian Mercer Award for Innovation for StarStream, a device that uses ultrasound and bubbles to enhance the cleaning power of a stream of water, saving water and energy along the way. His well-received book, The Acoustic Bubble (1994), is an essential volume for students and researchers of bubble acoustics. He also founded and Chairs the Network for Anti-Microbial Resistance and Infection Prevention (NAMRIP) and Health Effects of Ultrasound in Air (HEFUA).
