Dr. Queen Tannous is a teacher-researcher in mechanical engineering, specialized in manufacturing processes as well as the optimization of processes and products. Holder of a doctorate in engineering sciences from the University of Nantes (France), her research work focused on the study and optimization of an innovative continuous-welding process for polymer films intended for flexible-packaging applications. Her research falls within the fields of manufacturing processes, heat transfer, materials characterization, and the optimization of industrial performance. Before joining higher education in Lebanon, she worked as R&D manager at SEALESTER in France, where she led work on industrialization, process optimization, machine safety, and technological valorization, notably through the development of a patented technology. She has published articles on continuous heat-sealing technology and friction welding for soft-packaging applications, and teaches courses in quality management, ergonomics and human factors, mechanical structures, and introduction to industrial engineering.
