Dr. Mahmoud Ahmad Abu Saleem I am a Structural Engineering researcher and PhD graduate from The University of Queensland, with research experience spanning my Master’s by research at the University of South Australia and doctoral studies focused on sustainable structural systems, bio-based and recycled construction materials, experimental structural mechanics, durability-related behaviour, and computational modelling. My work centres on structural composites and concrete technologies, emphasizing their role in waste valorisation. My Master’s research extensively investigated the use of mixed recycled plastics (polymer wastes) in concrete and their mechanical and durability effects for kerb applications, including a first novel trial of microwave radiation treatment. My PhD developed and validated hybrid timber-cardboard sandwich structural composites, demonstrating the structural potential of waste cardboard (bio-based waste) for low-cost and bio-based housing applications. My work integrates large-scale experimental testing, sandwich composite fabrication, and analytical and numerical modeling to support performance-based, sustainable material design. I am passionate about translating waste-derived materials into practical, value-added structural solutions for resilient and low-carbon construction.
