A surface excited by transverse ultrasonic vibrations appears tactually smoother and more slippery. Controlling the amplitude of those vibrations allow for the development of a class of devices called Surface Haptic devices. They use the friction reduction principle to create rich stimuli ranging from shapes to textures.

My research is centered on understanding acoustic and tribological phenomena behind the friction reduction effect. Using laser doppler vibrometry, we characterize the acoustic behavior of the fingertip and its reaction to impact and harmonic stimulations. The data collected improve the current understanding of the nature of the friction reduction effect and is a ground for new type of tactile interfaces.

Before joining Northwestern, I did my PhD at the Université Pierre and Marie Curie in Paris, on the design of devices and algorithms for the capture and the rendering of tactile textures. The findings have been published in the book Reproduction of Tactual Textures: Transducers, Mechanics and Signal Encoding, as part of the Springer's Series On Touch and Haptic Systems.
