About Omar D Mohammed
Omar D. Mohammed joined Örebro University ORU in August 2025 as a senior Lecturer in Mechanical Engineering at the School of Science and Technology. Before joining Örebro University, he worked in different institutions in both academia and industry. He began his academic career in December 2005 when he was appointed as an Assistant Lecturer at the Mechanical Engineering Department, University of Mosul, Iraq. He was then promoted to a Lecturer in 2009, and he held this position till 2016. In October 2010, he joined Luleå University of Technology in Sweden to conduct his PhD studies. His research was focused on vibration-based gear fault detection. Within the period 2015-2021, he worked in the industry in Sweden. He worked as a Gear Development Engineer at GKN Driveline (renamed GKN Automotive) in Köping. He then joined a training program at Trafikverket in Luleå, and later he worked as a Gear Design Specialist and also as a Simulation Engineer at China-Euro Vehicle Technology CEVT (renamed Zeekr), which is an automotive engineering innovation centre under GEELY group in Gothenburg. In September 2021, Omar was appointed as an Assistant Professor at the Mechanical Engineering Department, Prince Mohammad bin Fahd University PMU, Saudi Arabia.
