Dr. Shaise K John is a Structural Engineer and researcher specializing in low-carbon cementitious materials, geopolymers, and reinforced concrete structures. He completed his Ph.D. at the College of Engineering Trivandrum, focusing on textile-reinforced concrete with geopolymer matrices for confinement and strengthening of concrete columns. His work bridges fundamental research and practical applications, emphasizing durability, freeze-thaw behavior, and performance-based retrofit strategies. Dr. Shaise has experience in numerical modeling, experimental testing, and performance evaluation of degraded reinforced concrete structures, and has contributed to numerical frameworks for optimal seismic retrofitting. He has published research on autogenous self-healing, fiber-reinforced composites, and low-carbon sustainable construction materials, and is actively pursuing projects aligned with sustainable development goals, circular economy, and carbon neutrality. Currently, he is involved in developing wood–geopolymer composites and bio-inspired materials for structural and functional applications. Dr. Shaise combines expertise in materials science, structural engineering, and computational simulations to advance sustainable and resilient construction technologies.
