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’s research interests are primarily in structural dynamics, with emphasis on vibration mitigation, structural monitoring and system identification, offshore dynamics and hydrodynamics. He has published about 300 international journal papers and conference papers, seven invited book chapters and a book. He has delivered more than 25 keynotes and many invited presentations in countries such as USA, Canada, UK, China, Japan, Australia, Greece, Portugal, Korea and India. He was a recipient of the prestigious Marie Curie Fellowship awarded by the Commission of the European Communities, as well as the IES Best Paper Award. He has been active in securing competitive university and external grants for research projects – more than S$13M including about S$7M as the principal investigator. The research projects include structural health monitoring, vibration mitigation, blast and seismic analysis, and offshore/marine engineering.
Prof. Koh has been active in the professional community. He is currently serving in four 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.
Prof. Koh was the Director of LRF Institute for the Public Understanding of Risk from May 2019 to June 2023. Currently he is the Director (Research) of the recently formed Coastal Protection and Flood Resilience Institute Singapore and the Director of Centre for Hazards Research at NUS.
