Ye Qian

Prof. Qian has obtained his Ph.D. at Columbia University in the City of New York, his M.S. at Hokkaido University in Japan, and his B.S. at Huazhong University of Science and Technology in China.

He worked as Research Fellow at Singapore Centre for 3D Printing. Before that, he also worked as Postdoctoral Researcher at Ghent University in Belgium.

He specializes in cement and concrete rheology, especially developing characterization methods to probe and control the viscoelastic properties of fresh cementitious systems and design of cementitious systems to improve processing during construction. He is also using nanoparticles and nanotechnology to obtain sustainable construction materials.
