Biography

Dr Mohamed is a lecturer at the School of Engineering and the Built Environment at Edinburgh Napier University. He joined Edinburgh Napier University as a PhD student in 2010 and became a zero-hour lecturer in January 2014, teaching math and civil engineering subject areas from undergraduate to MSc Levels. He promoted to a fix-term lecturer and senior research fellow since 2019, working on a bio-based composite materials in construction funded by Royal Academy of Engineering. Before joining Edinburgh Napier University, he worked as a teaching assistant and a lecturer in Civil Engineering Department at Omar Al Mukhtar University in Libya. He completed his B.Eng. in Civil Engineering in Libya and awarded the degrees of MSc (Hons) in Civil Engineering from Atilim University, Turkey.

Since 2019, Ahmed has led or co-investigated several research projects funded by the Royal Academy of Engineering, Scottish Founding Council and Energy Technology Partnership. His research outcomes have been published in several prestigious research journals in civil engineering subject areas. He is the first author or corresponding author for most of these publications.

Ahmed's research focuses on the area of timber engineering, bio-base composite materials in construction, non-destructive test technology in civil engineering. He is teaching the finite element module in MSc level and he has strong background in using the finite element software for modelling complex structures.
