Biography

Prof. Chu obtained his Ph.D. degree from The University of Hong Kong (Global 11th) with a full scholarship. His academic appointments at prestigious institutions include Endowed Principal Investigator at Columbia University (USA), Faculty at Penn State (USA), Research Fellow at NTU (Singapore), and Visiting Research Fellow at University of Cambridge (UK). His decade-long dedication is on sustainable, intelligent, and resilient infrastructure via advancing structural engineering and materials.

In 2025, he received the ACI Wason Medal for Materials Research (awarded only once globally each year since 1929). Since 2024, he has been ranked among the top 2% scientists (Career), and since 2022, among the top 2% (single year) by Stanford University and Elsevier. In 2015, he received the Hong Kong Government Green Innovation Merit Award. He is a full Member of ASCE, and ACI with an involvement in Committees 239 UHPC and 544 FRC. His research led to 77 publications in Q1 journals (including 4 highly cited papers and 1 best paper award) with 4000+ Google Scholar citations. Among these, 6 are single-authored, over 35 are first-authored, and more than 50 are first- or corresponding-authored. His publications include 3 single-authored papers in ACI Materials, 3 in Desalination / ACS journals, 8 in Cement and Concrete Composites / Cement and Concrete Research, and 8 in Engineering Structures / Composite Structures.
