Hong is a Senior Lecturer in the Department of Civil and Environmental Engineering. He was trained as a civil engineer at the University of Malaya, where he obtained a first class honours degree and a research MSc on calcined clay for high-performance concrete. He then joined Imperial College London to pursue a PhD on developing quantitative backscattered electron microscopy for characterising the microstructure of concrete. His thesis was awarded the W.C. Unwin prize in 2006. Following his PhD, he worked as a postdoctoral Research Associate to model mass transport properties of concrete based on the techniques developed during his doctoral studies. He became a member of academic staff in 2010. 

The microstructure of concrete is inherently complex and governs many aspects of the macroscopic properties of concrete structures. Hong's research aims to advance the understanding of how microstructure influences the performance, ageing and degradation of concrete structures. His work focuses on developing and applying imaging techniques to characterise microstructure, understanding mass transport processes that control concrete degradation and developing models to predict macroscopic properties from microstructure. He has expertise in 2D and 3D microscopy, X-ray microanalysis, image analysis, mass transport characterisation and computational modelling. 

Hong teaches MEng and MSc modules on Concrete Materials, Reinforced Concrete Design, Structural Mechanics and Sustainable Development. He is the Departmental Undergraduate Year 2 Coordinator and Postdoc & Fellows Champion. He also contributes to consultancy activities linked to his research thru Imperial Consultants (ICON).

Hong serves in the Editorial Board of Cement and Concrete Research and as Guest Editor for the journal Materials on its special issue on Image Analysis and Processing for Cement-based Materials. He is Chair of Scientific Committee and Steering Committee member of Nanocem. He also serves as Executive Committee member of the Applied Petrography Group and as Full Member of the EPSRC Peer Review College.
