Abstract: From acoustic levitation to sound beam tweezers, ultrasonic shrimp to light emitting bubbles, sound can be applied in ways that are often not understood. In this presentation, I will present some unconventional ways sound, and more particularly ultrasound, can interact with matter. I will focus on two intriguing wave/matter interactions: the tiny forces at play in acoustical levitation and the very aesthetic dancing soap film experiment.

Speaker Bio: After graduating in Physical Acoustics at the University Pierre et Marie Curie of Paris, I tackled a PhD (2011-2014) to understand the nonlinear interaction between acoustical vortex beams (a kind of sound tornado) with microscopic objects to develop the first “Acoustical tweezers” capable of a dexterous and contactless manipulation of matter. I have subsequently applied this knowledge for biophysical research in Caltech (2016) and, more recently, for the contactless manipulation of bubbles in Imperial College London as a Newton International Fellow of the Royal Society (2017-2018).
