PHD at the University of Geneva, France
Najib KACEM graduated in 2006 from the Arts et Métiers ParisTech engineering school. He joined the French Alternative Energies and Atomic Energy Commission to prepare for a Ph.D., which he completed in 2010. He subsequently undertook a post-doctoral research position at the University of Geneva. In 2011, he became an Associate Professor at the University of Franche-Comté in Besançon, France, holding a Chair of Excellence until 2016. He has been carrying out his research activities at the FEMTO-ST institute and has been the deputy director of the Department of Applied Mechanics since 2020. His areas of expertise and current research interests include MEMS/NEMS, Nonlinear Dynamics, Energy Harvesting, and Smart Materials and Structures. He has co-authored 60 journal publications, more than 90 conference papers, and has co-supervised 16 Ph.D. students. He has led and been involved in multiple industrial and academic projects, including a recent collaboration with THALES AVS on the design of tactical grade MEMS gyroscopes.

Research Focus
Najib Kacem’s research primarily focuses on the nonlinear dynamics of micro- and nanomechanical systems, with significant contributions to the development and optimization of MEMS (Microelectromechanical Systems) and NEMS (Nanoelectromechanical Systems) for sensor applications. His work enhances the performance of these devices, particularly in highly sensitive gas and mass detection, through innovations in nonlinear resonant cantilevers and hybrid vibration energy harvesters. Kacem’s studies extend to computational modeling, stability control, and energy localization in coupled oscillators, emphasizing the practical applications of these technologies in fields such as energy harvesting, mass sensing, and gyroscope design.
