  • Job Title :

    Assistant Professor

  • College :

    College of Engineering

  • Department :

    Mechanical Engineering

Dr. Omar has joined PMU in fall 2021, and he is working as an Assistant Professor in the department of Mechanical Engineering. He lived in Sweden since 2010, and he has several years of experience in teaching, research, thesis work supervision and engineering work in industry.

In 2002 Dr. Omar received his Bachelor’s Degree in Mechanical Engineering, with the grade ‘Very Good’, from the University of Mosul in Iraq. He then continued his studies at the same university and obtained a Master of Science in Applied Mechanics and Production in 2005. After that he started his employment as an Assistant Lecturer at the Department of Mechanical Engineering at the University of Mosul. In 2009 he was promoted to the position of Lecturer at the same department, where he continued to work until October 2010, when he obtained the opportunity to pursue PhD studies in Sweden. In 2015 he received his PhD degree in Operation and Maintenance Engineering from Luleå University of Technology in Sweden. The PhD research work was focused on dynamic modelling and vibration analysis for gear fault detection.

Dr. Omar has a number of publications in peer reviewed journals and international conference proceedings. His research interests include vibration analysis, stress analysis, gear design, optimization, condition monitoring, dynamic modelling and simulation. Moreover, Dr. Omar acted as a reviewer for different international journals and conferences.

On the other hand, Dr. Omar has about five years of industrial experience as he hold the position of Gear Development Engineer at GKN driveline in Sweden, and after that, the positions of Gear Design Engineer and Simulation Engineer at China-Euro Vehicle Technology AB (CEVT), which is an innovation vehicle technology centre under Geely group, and located in Gothenburg, Sweden. During his work in CEVT, Dr. Omar supervised different research projects in collaboration with different universities in Sweden.

Dr. Omar aims to contribute to promoting PMU research, developing curriculums and preparing a new generation of engineers those will shape the future of KSA and the region.
