Professor Yusuf SAHIN completed his B.Sc and M.Sc degree at Department of Manufacturing Technology of Gazi University in Ankara, Turkey. He joined to Production Research Group in Gazi University, worked as a research assistant till 1989. Funded by Higher Eduation Council (YOK) to United Kindom to do some researchers on “composites materials”. He awarded his Ph.D Degree in“Development of metal matrix composites, their mechanical and wear properties” at Department of Mechanical Engineering from University of Aston in Birmingham (UK), 1995. He was appointed as an Assistant Professor at Mechanical Education Department in Gazi University in Ankara, promoted to Associate Professor in 1996. From 1996 to 2002,worked as a Lecturer in Gazi University,and promoted to Professor as a Lecturer from 2002 to 2011.In 1999-2002, he was given a lecturer about “Mechanics”at Turkish Military Academy. He then was appointed as a Senior Lecturer at the Department of Manufacturing Engineering of Technology Faculty at Gazi University in 2011. He was given a lecturer about “Machine Theory”course at Department of Mechanical Engineering inAtilim University between 2010-2011 (part-time). Awarded a research by YOK to Virginia PolytechnicUniversity at USA in 2013 for a period of three months. Prof. Sahin has been currently funded by Turkish Scientific&Technical Council (TUBITAK) for investigation on “Sliding wear of polymeric based advanced composite materials” at Soete Lab of Mechanical, Construction&Production Engineering Department in Ghent University,Belgium. Prof. Şahin has concentrated on “Development of basalt fabric/carbon fabric-reinforced epoxy composites and their frictional behaviours”. Furthermore, ``Investigation of machining of the hard metals or hardened steels were carried out with using different cutting tool materials`` to find out optimum solution of parametric design in terms of surface roughness and tool wear. His research interests included Material&Mechanical sciences; Composite materials and Processing, Mechanical properties, Tribology, Powder metallurgy, Manufacturing processes, Metal cutting process, Machine Tools/Cutting tools, Polymer/Polymer composites, and Experimental design and analysis; Prediction of mechanical/tribological properties of metal matrix composites through Artificial Neural Network (ANN).
