Senior Research Fellow

Qualifications: BEng IMUST, MEng, PhD HIT

About Fei

Dr. Fei Yang received his PhD degree in materials processing engineering from the Harbin Institute of Technology, PR China, in 2010, working on hot processing of hard-deformed materials (e.g. titanium alloy and titanium aluminide intermetallics) and determining the hot deformation behaviour and mechanisms of the hard-deformed materials. Prior to joining the University of Waikato in 2011, Fei worked in the Guangzhou Research Institute of Non-ferrous Metals as a materials scientist from 2010 to 2011, where he worked on developing powder metallurgy processes and products. Currently, Fei is a key researcher and member of the Science Leadership Team of the TiTeNZ project, working with other research and industry partners on the commercialisation of powder titanium products in New Zealand. As a co-leader of the titanium research group at the University of Waikato, Fei is seeking to develop new materials and cost-effective processing routes for use in New Zealand manufacturing industry, and he has successfully initiated a new research area ─ cost-effective synthesis of advanced heat sink materials (e.g. copper/diamond composites) ─ in New Zealand, securing a prestigious grant from the US Air Force. Fei received the University of Waikato Early Career Research Excellence Award in 2017, and has been nominated for several other awards. Fei is currently supervising six PhD students at the University of Waikato and is also an appointed external PhD supervisor of the Harbin Institute of Technology; a committee member of the Society of Materials New Zealand Inc; and a member of TMS (the Minerals, Materials and Metals Society, US).
