I am materials engineer, I have a very good experience in metals manufacturing, fabrication, and heat treatment. Also, I have extensive knowledge in steel hardening on both scales (surface and through hardening) using several techniques, such as: electric resistance furnaces, salt bath furnaces, carburizing and carbonitriding, and flame hardening. Furthermore, I worked with Prof. Adnan I.O. Kilani as a research assistant for designing and manufacturing metal forming dies (deep drawing and asymmetric-angle extrusion dies). To fulfill my ambition, I decided to peruse my Ph.D study in Concordia University under the supervision of Prof. Mamoun Medraj as a step of coupling my practical experience with the academic part.
