Dr. Gehad Metwally | Sustainable Materials | Best Researcher Award

Obour Higher Institute for Engineering and Technology | Egypt

Dr. Gehad Ahmed Metwally is a civil engineering researcher focused on developing environmentally friendly and sustainable construction solutions that reduce carbon dioxide emissions. His work explores the use of bacteria in concrete to create self-healing bio-concrete, investigates the behavior and mechanical properties of fresh and hardened concrete using various materials, and examines the incorporation of natural and waste materials to minimize cement usage for lower CO₂ emissions. He also studies geopolymer concrete using fly ash, ground-granulated slag, and metakaolin combined with fibres such as steel and glass to achieve more resilient built environments. In his research role, he is responsible for data collection, reviewing recent literature, planning research, designing experimental mixtures, and performing tests to achieve optimal results, in addition to contributing to academic supervision. He has teaching experience in multiple civil engineering subjects and is skilled in SAP2000, ETABS, SAFE, AutoCAD, quantity surveying, and ICDL. His research contributions have been recognized with an appreciation certificate from the Dean of the Faculty of Engineering for publications in Q1 and Q2 scientific journals.
