I am a researcher and materials scientist specializing in thin films, optical coatings, and functional materials for sustainable and energy-related applications. I hold dual PhDs in Applied Physics and Materials Engineering from the University of Gabes (Tunisia) and the University of Minho (Portugal). My research focuses on the development and characterization of oxide-based coatings (TiO₂, ZnO, In₂S₃) deposited by techniques such as magnetron sputtering, spray pyrolysis, and sol-gel. I investigate their structural, optical, and photocatalytic properties for applications in UV protection, sensors, and renewable energy devices. I have contributed to several European-funded R&D projects, including Horizon 2020, SFERA III, FORC, FORCSFERA, and BioPiezoSenAct, focusing on enhancing the UV and mechanical durability of natural and recycled materials. My work bridges experimental materials science with innovation management and sustainable technology development. I have co-authored more than 25 peer-reviewed publications, with over 239 citations, a h-index of 10, and an i10-index of 10. I have also presented my research at several international conferences, including E-MRS (France), TechCon (USA), and PSE (Germany), among others. My current research interests include thin film deposition techniques, nanostructured materials, photocatalysis, optoelectronics, and the integration of scientific innovation in industrial and environmental contexts.
