Curriculum Vitae

Nickolas S. Sapidis is Professor of “Computational Design and Analysis of Machine Elements” with the Mechanical Engineering Department of the University of Western Macedonia (Kozani, Greece), where he directs the “Division of Constructions and Materials”. N. Sapidis has been pursuing/supervising research on “Mechanical Design”, “Computer-Aided Design (CAD)”, “Computer-Aided Engineering (CAE)”, “Geometric Modeling”, “Virtual Engineering”, and “Computer Graphics”. He is the author of more than 80 papers on the above subjects. His industrial professional experience on CAD/CAE includes the General Motors R&D Center, and the Marine Technology Development Co (Greece). Published research results of N. Sapidis have been independently implemented in industrial CAD systems by R&D teams at M.I.T., Intergraph Corp., General Motors Design Centre, Tribon (AVEVA), and Mercedes-Benz AG. N. Sapidis is a member of the Editorial Board of more than ten international scientific journals, including Computer-Aided Design (Elsevier), Computer-Aided Design and Applications (Taylor & Francis), and 3D Research (Springer). N. Sapidis has served on the Program Committee of more than 100 international conferences, and was an “invited Keynote Speaker” for 7 international conferences.
