Nikolaos Diafas is a materials scientist from Greece with a strong background in polymers, composites, and advanced functional materials. He completed his BSc in Materials Science at the University of Patras and later obtained an MSc in Science and Technology of Polymers and Composites from the same university. His master’s research focused on the development, characterization, and multifunctional performance of polymer matrix nanocomposites reinforced with silicon nitride nanoparticles.

While pursuing his master’s degree, he worked as a materials scientist in the field of electrochemical energy technologies, particularly focusing on polymer-based materials for high-temperature fuel cell applications. During this period, he was involved in research and development activities related to advanced functional polymers and gained practical experience in materials processing, characterization, and experimental optimization within an applied industrial research environment.

Within the ASSESS project, his research focuses on the development of multifunctional carbon nanotube (CNT)–doped thermoplastic fibers, strips, and veils with electrical conductivity and self-sensing capabilities for smart fiber-reinforced polymer (FRP) composites. These materials aim to enable rapid structural health monitoring of composite structures and improve manufacturing quality control by integrating sensing functionality directly into composite components.

Outside of his professional activities, he enjoys outdoor sports such as trail running, swimming, rock climbing, and cycling, reflecting his appreciation for endurance, exploration, and continuous personal challenge. He also enjoys learning foreign languages and discovering different cultures, which reflects his curiosity and enthusiasm for continuous personal growth and new experiences.
