Biography
Mathias Fink, born in 1945 in Grenoble, is a French physicist, professor at the École supérieure de physique et de chimie industrielles de la ville de Paris, member of the French Academy of Sciences and professor at the Collège de France.
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.
Mathias Fink is a professor of physics at the Ecole Supérieure de Physique et de Chimie Industrielles de la Ville de Paris (ESPCI) where he founded in 1990 the Laboratory Ondes et Acoustique. He pioneered the development of time-reversal mirrors 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. Four companies with close to 170 employees have been created from his research (Echosens, Sensitive Object, Supersonic Imagine and Time Reversal Communications)
