Biography
Dr Sifan Muhamad Ibrahim is a Lecturer in Structural Engineering at the University of Surrey. His research expertise lies in the fields of structural performance, fire engineering, and sustainable construction materials, with a focus on cold-formed steel systems, lightweight high-strength concrete, and composite structures.
Before joining the University of Surrey, Dr Ibrahim completed his PhD in Civil Engineering at Northumbria University, where he developed sustainable concrete materials, advanced finite element models and investigated the behaviour of innovative steel-concrete systems under various structrual loading.
In addition to his academic experience, Dr Ibrahim worked as a Research and Development Engineer at Bespoke Concrete Ltd., where he led the development of cost-effective Ultra-High Performance Concrete (UHPC) using locally available materials.
At Surrey, Dr Ibrahim contributes to both undergraduate and postgraduate teaching, delivering modules in structural and materials engineering . He is actively involved in supervising MSc dissertations and supporting student engagement through tutorials and laboratory demonstrations.
Dr Ibrahim’s current research focuses on low-carbon concrete, the durability performance of green lightweight high-strength concrete, the structural behaviour of steel–concrete composite beams and columns, and the fire performance of 3D-printed concrete–steel composite wall systems. He continues to expand his academic network through national and international collaborations.
