Dr.MostafaFahmiHassaneincompletedhisPhDatTantaUniversity,Egypt.During
hisstudyforthis,heparticipatedinadoctoralsteelcourseatLuleaUniversityofTech-
nology, Sweden. He is currently Professor of Steel Structures at the Department of
Structural Engineering at Tanta University. His research focuses on the analysis
and design of steel and composite structures, with the aim of improving the design
codes and standards that are currently used worldwide (e.g., EC3, EC4, AISC, and
AS 4100), to design more effective structures with minimized initial material costs
andlife-cyclecosts.Hehaspublishedmorethan95papersininternationaljournals.

his achievements, his biography has been accepted into Who’s Who in the World,
which is comprised of the top 3% of the professionals in Egypt. He also worked as
a Professor at Southwest Petroleum University in Chengdu, China between July
2019 and June 2020. More recently, he was named in Stanford University’s list of
the world’stop 2%of scientists, in2020, 2021, and 2022.
