Julien CARLIER

Julien CARLIER is a Lecturer at the Institut d'Électronique, de Microélectronique et de Nanotechnologie (IEMN) within the Institut des Sciences et Techniques de Valenciennes (ISTV) at the Université de Valenciennes et du Hainaut-Cambrésis (UVHC). He currently serves as Deputy Director of IEMN DOAE since January 2020, having previously served as Head of the MAMINA research group from September 2017 to December 2019. His academic career includes membership in the CSE 63rd section of UVHC (2007-2009), serving on the Board of Directors of ISTV (2007-2012), and managing the SPI Electronics Course at ISTV (2007-2012).

Dr. CARLIER earned his HDR (Habilitation à Diriger des Recherches) from the University of Valenciennes in 2016, following his Doctorate in Advanced Instrumentation and Analysis from the University of Lille 1 in 2004. His educational background includes an Engineer's degree from Polytech'Lille's Department of Instrumentation and a Master's in Advanced Instrumentation and Analysis, both obtained in 2001 from the University of Lille 1.

Dr. CARLIER's research focuses on high frequency acoustics on silicon, specializing in the development of ultrasonic transducers and high frequency resonators using thin layers of ZnO and monocrystalline LiNbO₃ on silicon for RF applications. His work spans micro and nanotechnology, ultrasonic propagation for biological environment interactions, and acoustic MEMS with applications in lab-on-chip systems. He has international collaborations with Wuhan University and Fudan University in China, as well as with the University of Fanar in Lebanon and IMEC in Leuven.

His publication record shows a consistent focus on high-frequency ultrasound applications, with particular emphasis on MEMS integration, acoustic wave propagation in silicon substrates, and lab-on-chip implementations. The research demonstrates progression from fundamental materials characterization to increasingly sophisticated integrated systems for both industrial and biological applications.

Dr. CARLIER has coordinated significant research projects including the French-International PICS CNRS program "Lab-on-Chip for biological high frequency acoustic characterization" (2010-2012) with 21k€ funding, participation in the ARCIR project (2007-2009) with 110k€ funding, and the Interreg IV PRISTIMAT project (2008-2010) with 300k€ funding. His international collaborations have resulted in multiple joint publications with Chinese universities.

He leads the MAMINA research group at IEMN, focusing on micro and nanotechnology applications in acoustics. His team works on developing high-frequency ultrasonic transducers and resonators, with applications ranging from RF components to biological characterization systems. The group maintains strong international connections, particularly with Chinese institutions, facilitating knowledge exchange and collaborative research in advanced acoustic technologies.
