Dr. Nikoletta Sargioti
Materials Engineer
Dr. Nikoletta Sargioti is a Materials Engineer, with an integrated MSc in Materials Science and Engineering and a PhD in Mechanical and Manufacturing Engineering.
Dr. Nikoletta Sargioti
During her MSc, which was awarded by the University of Ioannina, Nikoletta developed a comprehensive understanding of material properties and their applications across various industries. She obtained her PhD in 2023 from Dublin City University, Ireland where she focused on metal-based minimally invasive medical devices and advanced 3D printing techniques. During her PhD, she engaged in numerous collaborative projects within the aerospace, automotive and biomedical industries focusing on the development and application of metal-based technologies. Her expertise is focused on the analysis, optimization, design and development of advanced materials using computational and factorial designs. She possesses an in-depth knowledge in the comprehensive characterisation of materials—including their physical, chemical, and mechanical properties.
Nikoletta’s Ph.D. journey was particularly transformative, improving her abilities in both independent and collaborative work, strengthening her abilities in leading complex projects. Actively contributing to the scientific community, she presented her findings at more than ten national and international conferences.
