Dr ONG Ghim Ping Raymond is an Associate Professor and Deputy Head (Research) in the Department of Civil and Environmental Engineering at the National University of Singapore (NUS). He is concurrently the Director (Operations) at the Coastal Protection and Flood Resilience Institute (CFI) Singapore at NUS. Dr Ong graduated with a B.Eng (Civil) (First Class Honours) with a minor in Business from the National University of Singapore in 2003 and obtained his PhD in Civil Engineering from the National University of Singapore in 2007. Before his current appointment, he worked as a postdoctoral research associate in the School of Civil Engineering at Purdue University from 2007 to 2008 as a visiting assistant professor in the same university in 2009 and then as a lecturer (from 2010 to 2014) and assistant professor (2014-2020) in the Department of Civil and Environmental Engineering at the National University of Singapore.

Dr Ong’s research interests include sustainable pavements for a circular economy, and multimodal transport infrastructures and operations, with emphasis on future mega-transport infrastructures/operations (such as car-lite/car-free towns, next-generation seaports and airports). He has authored or co-authored over 85 peer-reviewed journal articles as well as over 120 international conference papers/ presentations in these research areas. He is also actively involved in translational research grants/projects related to the engineering development of critical mega-infrastructures in Singapore (including the Tuas mega-port, Changi East Development, and Woodlands Checkpoint).

Dr. Ong is currently serving on various scientific committees in the American Society of Civil Engineers, the America Society of Testing and Materials, the Eastern Asian Society of Transportation Studies, and the World Transport Convention (China). Nationally, he is currently serving as a Council Member of the Singapore Road Safety Council (SRSC) and in several technical and standards committees in Singapore. Dr Ong is also serving in editorial roles in several peer-reviewed international journals. He has received several scientific awards in recognition to his achievements in transportation research, including the Alfred Noble Prize (ASCE), the Hanjin Prize (IAME), the inaugural Takeuchi Yoshio Award (OCDI), the inaugural iSMARTi Early Career Award and subsequently the iSMARTi Achievement Award. His research expertise and achievements have also led to him to serve as consultant to agencies and companies such as Changi Airport Group, Defence Science and Technology Agency, Surbana Jurong Infrastructures Pte Ltd, Global Maritime and Port Services Pte Ltd, and the Korean Maritime Institute.

Dr. Ong is also passionate about sharing his thoughts on current and future issues related to his research expertise to the public. He has frequently appeared in mainstream print or internet media (such as Straits Times, Lianhe Zaobao, The New Paper, Today Online) and live or pre-recorded TV interviews (such as Channel NewsAsia, Channel 8 info-ed programs and news, and Suria info-ed programs) speaking on issues on transport infrastructure and operations, active mobility and car-lite/car-free initiatives.
