I received my bachelor degrees in Mechanical Engineering in 1986 from the National School of Engineers of Tunis (Tunisia). The strong desire to pursue a research career in “Applied Mechanics” arises because of the good interaction with my professors (from different countries: France, Russia, Spain, Poland…) who showed me the beauty of science. I graduated with “Principal Engineer” title and then worked as Technical Manager of the “Wires and Transmission Accessories” Company for almost one year.
In 1987, I was chosen, among a group of ten best graduates from all Tunisian Universities, to continue graduate studies in North America. I joined the Polytechnique of Montreal (Canada), where I finished my Master of Science in Applied Mechanics in 1989. My Master project was entitled: “Effect of Initial Imperfections on Dynamic Stability and Response of Rectangular Plates”. The work contained extensive modeling of the dynamic behavior of initially curved plates when load by in-plane forces. As a result, I had my first journal paper published in the “Journal of non-linear dynamics”. I continued my research on plate’s instabilities in the same department of Applied Mechanics. I obtained my Doctorate of Philosophy (Ph.D.) in 1993 on a thesis entitled “Dynamic Stability and Resonance of Imperfect Rectangular Plates”. In my dissertation, I explained the mechanisms of interaction between different types of instabilities affecting the vibration of initially deformed plates. The results of my Ph.D. work were four new papers published in highly ranked journals.
My career was particularly shaped when I met Professor Marc Thomas (my Ph.D. external examiner), who offered me a Post-Doc position in his laboratory. Since then, I became interested about the “Condition Monitoring” of rotating machinery by vibration techniques.
In 1994, I went back to Tunisia to work again in Industry. I served as Technical Manager of “SOFEMED”, the first company in Africa & Arab Word to design and Manufacture Orthopedic components and Medical Accessories. As a result of my intensive research and development, I managed to manufacture with success bones lateral external fixation systems and orthopedic implants for the first time in an Arabic Country. When I moved later to “INTERMETAL”, a hot rolling mill, I succeeded to understand the origin of frequent bearings failure and helped to solve the problem allowing the company to save hundreds of thousands of dollars.
At the beginning of the academic year 1997-1998, I joined the National Institute of Applied Science and Technology of Tunis (INSAT), department of Physics and Instrumentation, as an assistant professor. I taught several courses in mechanical engineering and built the first laboratory of Industrial Maintenance and Troubleshooting of Rotating Machines. I started working on the development of intelligent car dampers by using electro-rheological and magneto-rheological technologies. My other current research activities include the numerical simulation of vibration response of damaged ball bearings. My active collaboration with people from Canada and France permitted to develop a powerful and user-friendly software called BEAT (BEAring Toolbox) able to simulate the vibration response of ball bearings when affected with different types of surface degradation and under different running conditions. The results of supervising several final year projects, master and Ph.D. dissertations allowed me to publish several journal and conference papers related to those subjects.
In September 2012, I joined Qatar University to teach a wide variety of mechanical engineering courses.
