Non Destructive Testing
Serge Dos Santos was born in Valenciennes, France, in 1971. In 1995, he received the ‘Diplôme d’Etudes Approfondies’ of Physics with the mention ‘Molecular spectroscopy and nonlinear physics’ from the University of Dijon, France. He worked at the FEMTO Institute (LPMO CNRS), Besançon, France, on the study of the origin of low-frequency fluctuations in ultrastable oscillators. He obtained a PhD degree in Engineering Science in 1998 for his contribution to understanding the link between low-frequency noise and nonlinearity in synchronised systems. Then he joined the Ultrasonic Group ‘GIP Ultrasons’, created by Professor Léandre Pourcelot at Tours, France, working on the development of new medical and non-destructive testing (NDT) applications of nonlinear acoustics for ultrasound imaging. In 1999, he obtained an Associate Professor position at the LUSSI-CNRS Laboratory, directed by Professor Frédéric Patat, also devoted to fundamental research on nonlinear acoustics and signal processing. In 2005, he was an invited researcher at Artann Laboratories Inc (USA) working on the development of nonlinear time reversal acoustics methods. At 37 years old, he received his ‘Habilitation à Diriger des Recherches’ from the University of Tours, France. He is now Associate Professor (Hab. Dir. Rech.) at the INSA Centre Val de Loire (INSA CVL), Blois, France, where he is involved in the organisation of the international exchanges of students and researchers. Since 2007, he has given lectures related to nonlinear signal processing and non-destructive testing (NDT) within the ERASMUS framework at Prague Technical University and the University of Valencia in Spain. At INSA CVL, he is responsible for signal processing, advanced control and nondestructive testing lectures. Since 2009, he has conducted his research at the U930 ‘Imaging and Brain’ Inserm-University Francois-Rabelais Research Laboratory, directed by Professor Denis Guilloteau, working on biomedical applications of the advanced signal processing methods developed for the nonlinear NDT of complex materials. Since 2000, his research projects have included ultrasonic characterisation of material using nonlinear acoustics (AERONEWS FP6 European project) for the aeronautic industry, advanced nonlinear signal processing using Lie groups, and nonlinear analysis of ultrasound contrast agent for complex imaging and therapy applications. In 2013, he starts to apply TR-NEWS methods for the acousto-mechanical characterization of the human skin ageing within the responsability of the PLET projet, granted by the Region Centre and labelized by the Cosmetic Valley cluster. During the last 10 years, Serge Dos Santos conducted experimental research within invited stays at Artann Laboratories (2005 and 2007, Princeton, NJ, USA), Nottingham University (2005, UK), Exeter University (2007, UK), VZLU Center (2006 and 2007, Prague), University of Valencia (2011, Campus Gandia), and BAM (2013, Berlin) in order to test and validate "nonlinear time reversal" based NDT systems. His bibliography contains 173 references; H-index 2012: 5; Number of co-authors: 93; Publications in international journals: 18; Invited conferences with publications: 7; International and National proceedings: 111; Reports and Seminar: 37. In 2010, he was awarded by Academia NDT International as a Full Member (ECNDT 2010, Moscow), responsible of the Signal Processing Chapter. During the last years, he was chosen as a member of the Scientific Committee for the VIth International Workshop NDT in Progress Meeting of NDT Experts, 10-12 October 2011, Prague, Czech Republic; the 12th International Conference titled ˝Application of Contemporary Non-destructive testing in Engineering˝ in PORTOROŽ, Slovenia, September 4th - 6th, 2013; ECNDT 2014, October 2014 ; IEEE BEC2014, the 14th Biennial Conference on Electronics and Embedded Systems, Tallinn, Estonia on October 6-8, 2014. Tallinn University of Technology and the 19th World Conference on Non-Destructive Testing WCNDT 2016, Munich, Germany.
