Biography

Oscar K.S. Hui received his Ph.D. degree in mechanical engineering at the Hong Kong University of Science and Technology (HKUST) in 2008. HKUST ranks #47 in THE world ranking 2020.

He is a reader in mechanical engineering in School of Engineering at UEA. Prior to that, he was a lecturer in the department of systems engineering and engineering management of the City University of Hong Kong, Hong Kong (Aug 2008 - Feb 2013), an Assistant/Associate Professor in the department of mechanical engineering at Hanyang University, South Korea (Mar 2013 – Aug 2016), and a lecturer in mechanical engineering in School of Mathematics, University of East Anglia, UK (Sep 2016 – Jul 2019). 

As PI, he has secured GBP 1.1  million to conduct research projects (GBP 2.4 million as both PI and Co-I). The funding is from General Research Fund of Hong Kong, Innovation and Technology Fund of Hong Kong, National Research Foundation of Korea, The Science and Technology Development Fund of Macau, Ove Arup & Partners Hong Kong Ltd., Hysan Development Company Ltd., ASA Innovation & Technology Limited, among others.
