Short Description

Dr Jiao is an assistant professor of materials science at the Department of Mechanical Engineering of PolyU. He received his PhD degree under the supervision of Prof. CT Liu from City University of Hong Kong in 2014 and subsequently worked as a postdoc in the same group. Before joining PolyU in 2017, he worked on nanomaterials in Prof. Christopher A. Schuh’s group at Massachusetts Institute of Technology.

His research interests focus on the development of advanced structural materials, including ultra-high strength steels, high-entropy alloys, high-temperature superalloys, and nanostructured metals & alloys. His group is utilizing their expertise in computational modelling and design, innovative processing, and mechanical and microstructural characterization to develop new materials for a wide range of technological applications, including aerospace, automotive, marine, construction, and energy industries.
