Biography

Ezzeldin Yazeed is a professor and director of the graduate program in the Department of Construction Engineering at The American University in Cairo. 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 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. He is a voting member of the permanent committee for the Egyptian Code of Practice for Fibre Reinforced Polymers and the Chair of the Technical Subcommittee, preparing the Egyptian code of practice for composite polymers structures. He was also a member in many engineering societies, such as IABSE (Switzerland), CSCE and CPCI (Canada), ASCE, SEI and TMS (U.S.). Yazeed was awarded the State Award in Engineering Sciences (Egypt) in 1999 and the Bruce M. Irons Memorial Scholarship (Canada) 1 in 1994. 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, 142 publications, of which 53 papers appear in journals. His Author h-index as of June 2017 is 14 (google) and 11 (Scopus). He supervised 25 MSc and 8 PhD students, and examined 27 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 AdbdulAziz 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.
