Bruno Gilles received his Ph.D. degree in physics in 2001 from the Ecole Normale Supérieure de Lyon, where he studied the role of disorder on acoustic wave propagation in granular media. Dr. Gilles subsequently joined the U556 laboratory of the INSERM, as a postdoctoral research fellow, working on the effect of a bifrequency excitation on ultrasonic cavitation.

He was then recruited in 2002 as an associate professor of Mechanical Engineering in Polytech Lyon, the college of Engineering of the University Claude Bernard Lyon 1, conducting his research in the field of therapeutic ultrasound, including the use of cavitation for therapeutic applications. From 2009 to 2015, he has been head of the Mechanical Engineering Department of Polytech Lyon, and academic dean of Polytech Lyon from 2015 to 2017.

His research interests focus on the development of methods for cavitation activity control and regulation, including real-time regulation, passive imaging of the cavitation activity or the use of multifrequency excitations to modify some aspects of cavitation dynamics, within the perspective of an application to ultrasound thrombolysis. More recently, he initiated some work on the characterization of the properties of streaming flows induced by focused ultrasound using PIV.
