Ezzeldin Yazeed is a professor and chair of the Department of Construction Engineering at The American University in Cairo (AUC). He is a fellow of the Academy of Scientific Research and Technology (ASRT), and a reinforced concrete and steel structures consultant in Egypt. He was previously a professor at Ain Shams University and served as the acting director of the New Credit Hours Engineering programs of Ain Shams University between 2007 and 2008. He was the associate dean of the College of Engineering of Qatar University from 2005 to 2006.
Ezzeldin Yazeed is a program reviewer for the Accreditation Board for Engineering and Technology (ABET) since 2018. He is a voting member of the Egyptian Code of Practice Committee for Steel Structures and the Egyptian Code of Practice for Fibre Reinforced Polymers. He was also a member of many engineering societies, such as the American Society of Civil Engineers and Stockholm Environment Institute in the USA, the International Association for Bridge and Structural Engineering in Switzerland, and the Canadian Society for Civil Engineering and CPCI Canadian Prestressed Concrete Institute in Canada.
Yazeed was awarded the State Award in Engineering Sciences (Egypt) in 1999 and the Bruce M. Irons Memorial Scholarship in Canada in 1994. He was also awarded the excellence in teaching award from the AUC in 2019. His biographical profile has been listed in Marquis' "Who’s Who in Science and Engineering", "Who’s Who in the World", "Who's Who in Engineering Higher Education" since 2006. He has one U.S. Patent, 195 publications, of which 64 papers appear in journals. His Author h-index as of Dec. 2020 is 16 (google) and 13 (Scopus). He is recognized in 2020 among the highest cited researchers in the world in the study published by a group of Stanford University researchers. He supervised 30 MSc and 8 PhD students and examined 39 theses and dissertations. He is a reviewer for many international and regional journals as well as conferences.
Yazeed designed/design-reviewed many iconic projects such as the Four 140 m high Minarets of Al-Haram AlMakki Extension, (KSA), Al-Haram FRP Temporary Mataf (Makkah), FRP Clock of King Abdulaziz Endowment Tower (Makkah), Cambambe Hydroelectric Power Plant and Dam (Angola), Storm-water Drainage for Muna and Muzdalifah, (KSA) and many other reinforced concrete and steel structures.
Teaching Interests
Ezzeldin Yazeed believes that a good instructor should help students answer questions they do not know yet how to ask. Furthermore, he always accepts the fact that whatever is learned and mastered for some time will always be surpassed by what will work better; he always accepts to replace what he knows with what works better. In teaching, his primary teaching objective is to offer students a skilled-based learning experience as opposed to a knowledge-based one. He is always adopting teaching paradigms, which are learner-centered. He is interested in new teaching/learning pedagogy, which includes, but are not limited to: Blended learning, Flipped Classrooms, Student-generated examinations and classes, Design competitions.
