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.
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)
