Biography

Dr Koh is a Professor of Civil Engineering and graduated with First Class Honours in 1979 from the then University of Singapore. Upon completion of his national service, he joined the NUS as a senior tutor in 1981. Subsequently, he went on a NUS overseas scholarship to further his graduate study at the University of California, Berkeley, where he obtained his M.S. and Ph.D. in 1983 and 1986, respectively. His Ph.D. thesis was entitled “Modelling of Dynamic Response of Elastomeric Isolation Bearings”.

Prof Koh has made internationally recognized contributions that have advanced the fields of structural dynamics, structural health monitoring, offshore engineering, and, more recently, coastal engineering.  He has published more than 140 international journal papers, together with seven invited book chapters and a book. His work has received over 7,100 citations with an h-index of 47. His scholarly achievements have earned significant international recognition, including ranking among the top 0.5% of scholars worldwide by ScholarGPS (2024–2025) and inclusion in Stanford University’s Top 2% Scientists list for both career-long and annual impact. He received the IES Prestigious Publication (Theory) Award and Top-Three Project Award by the Singapore Maritime Institute. He has also delivered about 30 invited keynote lectures across Europe, North America, and Asia, and serves on the editorial boards of several international journals in structural health monitoring and ocean engineering. Through these roles, Prof Koh has helped shape research directions in his field and strengthened the global visibility and reputation of NUS civil engineering research.

Prof Koh has developed several original methodologies that have advanced the state of knowledge in engineering mechanics and structural monitoring. His Koh–Kelly model for viscoelastic bearings in seismic base isolation has been widely cited and adopted in Japanese design guidelines for elastomeric bearings. He was the first to develop the sub-structural identification strategy, a divide-and-conquer approach that overcomes the combinatorial complexity associated with identifying large systems in structural health monitoring. He subsequently proposed the Moving Element Method for efficient numerical simulation of engineering systems involving moving objects or loads that would otherwise exit the computational domain. In recent years, he expanded his research from structural engineering to offshore and marine engineering through the development of the Consistent Particle Method (CPM). By addressing the insufficient consistency in spatial derivative computation inherent in mainstream particle methods such as SPH, CPM has enabled accurate simulation (without the use of artificial values of physical parameters) of extreme wave hydrodynamics, fluid–structure interaction, large-deformation geomechanics, and sediment transport/erosion processes in coastal and offshore engineering.

Prof Koh has been active in the professional community.  He is currently serving on several journal editorial boards, including as an associate editor of a US-based journal on Structural Health Monitoring.  His expertise in structural engineering (structural dynamics in particular) has been well sought after by the industry.  He has conducted more than 40 short courses for the industry, including about 20 on seismic analysis and design (EC8).  He has served as advisor/specialist in more than 130 infrastructure and industrial projects, including vibration studies of many major developments such as high-tech buildings, train track systems, bridges, and offshore systems, in Singapore and the region.
