About

Nizar Lajnef is a leading researcher in structural health monitoring (SHM) and smart infrastructure, with a focus on integrating Internet of Things (IoT) technologies into civil engineering. His work centers on developing self-powered sensing systems and data-driven methods for real-time damage detection in bridges, buildings, and pavements. Lajnef’s most-cited paper, "Internet of Things-enabled smart cities: State-of-the-art and future trends" (2018, 402 citations), provides a comprehensive roadmap for IoT-driven urban infrastructure, highlighting how wireless sensors and machine learning can transform maintenance and safety. He has pioneered the use of piezoelectric energy harvesters to power sensors from ambient vibrations, eliminating battery dependency. His contributions have advanced the field of cyber-physical systems for infrastructure, enabling continuous, low-cost monitoring that prevents catastrophic failures. With over 400 citations on his seminal work alone, Lajnef’s research has influenced both academic theory and practical applications in smart city development. He is also recognized for his work on probabilistic fatigue life prediction and has received multiple grants from agencies like the National Science Foundation, cementing his role as a key innovator in resilient, data-driven infrastructure.
