Mathias Fink, born in 1945 in Grenoble, is a French physicist, professor at ESPCI Paris and member of the French Academy of Sciences.[1]

Life and career[edit]

Mathias Fink received a M.S. degree in mathematics from Paris University, and the Ph.D. degree in solid state physics. Then he moved to medical imaging and received the Doctorat es-Sciences degree from Paris University in the area of ultrasonic focusing for real-time medical imaging under the direction of Pierre Alais (1978).[2]

In 1981 he was appointed Professor at the University of Strasbourg. After a stay as a visiting professor at the University of Irvine in the radiology department he returned to France to become professor at the Paris Diderot University (Paris 7). In 1990 and founded the "Waves and Acoustics Laboratory" at ESPCI whose director he was and which became the Institut Langevin in 2009.[3] 2005 he was appointed professor at ESPCI, where he now is professor emeritus and holds the Georges Charpak chair.

Fink pioneered the development of time-reversal mirrors[4] and Time Reversal Signal Processing. He developed many applications of this concept from ultrasound therapy, medical imaging, non-destructive testing, underwater acoustics, seismic imaging, tactile objects, to electromagnetic telecommunications. He also pioneered innovative medical imaging methods: transient elastography, supersonic shear imaging and multi-wave imaging that are now implemented by several companies. Six companies with close to 400 employees have been created from his research: Echosens,[5] Sensitive Object,[6] Supersonic Imagine,[7] Time Reversal Communications, Cardiawave,[8] and GreenerWave.[9]
