Stefan Catheline received the Diplome d’Etudes Approfondies (M.Sc. degree) in physics and acoustics (1994), his Ph.D. degree in physics (1998) from University of Paris VII (Denis Diderot) for his work on transient elastography and his “Habilitation de Recherche” in 2006.
After a post doc at the University of California, San Diego, he become an assistant Professor at University of Paris VII in 1999 and joined the laboratory Ondes et Acoustique at the Ecole Supérieur de Physique et de Chimie Industrielle de la ville de Paris (ESPCI). From 2005, he has been working for a two years mission at the University of Montevideo (Uruguay) and was assistant Professor at University of Grenoble at Isterre until 2012. He is now Director of research at INSERM unit 1032, in the Laboratory of Therapeutic Applications of Ultrasound (LabTAU) directed by Jean-Yves Chapelon in Lyon. His current research activities at the head of the team “Ondes et instrumentation” include acoustic topics such as elastography, time reversal, seismology, reverberant cavities, nonlinear elasticity, tactile interface, source localization as well as HIFU. He holds 8 patents in the field of ultrasound and seismology and wrote more than 100 articles. He has been co-founder of two companies: Sensitive Object in the field of acoustic interactivity and SEISME in the field of elastography.
He has been member of the following laboratories:
- LOA now the Institut Langevin, ESPCI, University of Paris
- MPL Scripps Institute, University of California, San Diego, USA
- LAU Instituto de Fisica de Montevideo, Uruguay
- LGIT, now the Institut des Sciences de la Terre, University of Grenoble

Selection of papers (7) with short description:
Applied Physics. This paper describes for the first time transient elastography. This technique is used in the Fibroscan®, a commercial device made by Echosens for hepatic deseases diagnostic.

Academic Physics. 56 years after the observation of a non linear acoustic wave, this paper describes the experimental observation of a non linear transverse wave. It suggests the existence of a relation ship between linear and non linear elastic coefficients, not described at that time by standard theory of elasticity.Ing, Quieffin, Catheline, Fink, In solid localization of finger impacts using acoustic time-reversal process, Appl. Phys. Lett., 87 , 204104, 2005
Applied Physics. This paper is at the origin of the first commercial application of time reversal in the field of acoustic interactivity. It is now part of the Sensitive Object® technologyS. Catheline, N. Benech, X. Brum, and C. Negreira, Time reversal of elastic waves in soft solids, Phys.Rev.Letter, 100, 064301, 2008.
Academic Physics. Transient elastography allows to observe time reversal of elastic waves inside a soft solid. The Rayleigh criteria for solid imaging is direction dependant. This experiment opens up the way to time reversal tomography of soft tissuesT.Gallot, S. Catheline, P. Roux, J. Brum, N. Benech, C. Negreira, Passive elastography: Shear wave tomography from physiological noise correlation in soft tissues, IEEE Transactions on UFFC, vol. 58, no. 6, June 2011.
Applied Physics. In this paper, an elastography experiment is conducted in vivo in the liver. The novelty is that no shear wave sources are used for the tomography reconstruction. Natural vibrations created by muscles activities (heart) are used in this first passive elastography imagingBrain palpation from physiological vibrations using MRI, PNAS, 112 (42) 12917-12921, (2015)
Medical imaging: Natural vibration together with an MRI visualisation is used to obtain a passive elastography map of the brain.
