Du Hongjian

Biography

Dr. Du Hongjian obtained his BEng and PhD from Shanghai Jiao Tong University in 2007 and the National University of Singapore in 2012, respectively. He worked as a Research Fellow and then Senior Research Fellow at NUS and Lecturer at Swinburne University of Technology, Australia. Dr. Du joined CEE as lecturer since 2020.

Hongjian is a passionate educator. He strives to provide fruitful learning experience to his students in lecture theatres, laboratories, and online classrooms. He applies active and experiential learning techniques to his teaching, aiming to foster his students’ holistic development in critical thinking, problem-solving skills, interdisciplinary collaboration, etc. He has been nurturing undergraduate students the skills to solve challenges by mentoring them in international and national competitions.

Hongjian has a strong research focus on (1) digital fabrication of reinforced concrete to increase construction automation and (2) development of low-carbon building materials to combat climate change. He specializes in microstructural characterization and performance assessment of concrete. He is now mentoring a group of researchers on interesting but challenging topics including 3D concrete printing, embodied carbon calculation, carbon sequestration, upcycling waste in concrete, etc. Hongjian provides professional consultancy to the construction and concrete industry.

Hongjian is proactive in translating his research to products to impact the society. He holds a few inventions and patents related to green cement and low-carbon building materials. He is the co-founder of CIRCRETE, a deeptech startup visioned to decarbonize the built environment.
