Hay Wong (HW) read Mechanical Engineering and obtained both B.A and M.Eng degrees from the University of Cambridge, UK (2008-12). Following graduation, he worked as a Research Engineer at Stryker Orthopaedics – a Fortune 500 US medical devices manufacturer (2012-14). HW then pursued his industry-sponsored Ph.D at the University of Liverpool under Prof. Chris Sutcliffe and Dr. Peter Fox (2014-19). After working briefly as a Postdoctoral Research Associate at Liverpool, he joined the Department of Mechanical and Automation Engineering, Chinese University of Hong Kong as an Assistant Professor in 2020.

HW’s research interests include metal additive manufacturing, quality control, and instrument/ prototype development (mechanical, electronics, and software). His Ph.D work on in-situ monitoring of the Electron Beam Additive Manufacturing process has earned him 2 international patents-pending and 2 IET Innovation Awards. HW is the first/ solo author of 8 published peer-reviewed journal articles. He serves on the judging panel for the IET E&T Innovation Awards 2020, whilst being a referee for both the Elsevier Additive Manufacturing Journal and the Wiley & Hindawi Scanning Journal.
