Présentation

Franck Levassort was born near Paris, France. He received the bachelor’s degree in applied physics and the DEA (M.Sc.) degree in physical acoustics from University Paris 7-Denis Diderot, Paris, in 1990 and 1991, respectively, and the Ph.D. degree in ultrasound from the University of Tours, Tours, France, in 1996. From 1997 to 2013, he was an Assistant Professor and since 2014, he has been a Full Professor of Electrical Engineering with the Institute of Technology, University of Tours, Blois, France. Since 2024, he has been Director of GREMAN, Tours, a laboratory of more than 120 in the field of materials, microelectronics, acoustics, and nanotechnology. His current research interests include design, modeling, and characterization of piezoelectric composite materials and structures, as well as transducers for imaging applications.
