Dimitrios Tzetzis

Dr. Dimitrios Tzetzis holds a BEng (Hons) in Mechanical Engineering and an MSc in Advanced Manufacturing Systems from Kingston University, London, UK. He was also granted a PhD in Mechanical Engineering from Queen Mary, University of London, UK. He worked as a member of the Centre for Materials Research (CMR) where he focused his research in the design, analysis and manufacture of composite materials for aerospace structures.

He has been involved in various research and development projects in the areas of composite materials and experimental mechanics while his current research interests are focused on the design, analysis, manufacture and testing of nanocomposites. His research activities in the International Hellenic University are within the framework of the MSc in Strategic Product Design and they are related to modules such as materials selection, mechanics, computer aided design along with reverse engineering and rapid prototyping that lead to engineering product innovation.

Dimitrios is a member of the IMechE, IOM3, SPE, ESCM and he has a broad teaching experience as a visiting lecturer in various educational establishments. He is also a reviewer of various international scientific journals and has several publications in peer reviewed international journals and international conference proceedings.
