From 2004 to 2019, I was a university professor at University of Bejaia. During this period, in addition to my duties as a teacher-researcher, I was Chairman of the Scientific Committee of the Physics Department, Chairman of the Scientific Advisory Board of the Faculty of Exact Sciences and Director of the Theoretical Physics Laboratory. Since October 2019, I have joined the University of Batna 2, where I hold the position of professor and chair the Scientific Committee of the Common Core Department.
