Professor Yu is a Professor in the Department of Aviation and Aeronautical Engineering, Hong Kong Polytechnic University. He is also concurrently the Head of Training for Flight Training Organization (HKCAD-509A) and Training Manager for Licensed Aircraft Engineers (HKAR-147) at the university. He was formerly the Head of the Department from Aug 2018 to Nov 2019.
Prior to joining HKPolyU, he was with the Nanyang Technological University(NTU), Singapore (1991-2013) and Singapore Institute of Technology(SIT) (2013-2018). He held various administrative positions at NTU including (1) Head, Division of Aerospace Engineering in the School of Mechanical and Aerospace Engineering (2008-2013), (2) Director, Master of Science Programme in Aerospace Engineering with the Technical University of Munich, Germany (2011-2013), (3) Vice-Dean, Office of Admissions (2003 - 2006), (4) Member of the University Council (now Board of Trustee) (2001-2003), (5) Principal Staff Officer, President’s Office (2000-2003) and (6) Director, Part-time Master of Science Programme in Biomedical Engineering with the Singapore General Hospital (1999). At SIT (7), he was the founding Programme Director for Sustainable Infrastructure Engineering (Land & Building Services) (2013-2018). During his tenure as Head of Aerospace Engineering at NTU in particular, he had successfully obtained a SGD 50 million Grant from CAAS to establish the Air Traffic Management Research Institute (ATMRI). He also helped to establish the LTA Research Centre for Railway Engineering at SIT.
Professor Yu was also an Adjunct Professor to the Department of Architecture and Building Sciences at the Xi’an JiaoTong University, China (2015-2018), a Visiting Scientist to the Department of Mechanical Engineering at the University of Tokyo, Japan (2007) and the Institute of Fluid Mechanics at the University of Erlangen, Germany (1999). He is currently trainer for holistic gas turbine at Rolls Royce Aeroengine Singapore (since 2009).
Professor Yu is an Independent Non-Executive Director of SBS Transit Ltd. He is also the Chairman of the Service Quality Committee (since 2018).

Professor Yu’s research interest is on non-intrusive measurement techniques for fluid flow such as, Laser-Doppler Anemometry, Phase-Doppler Anemometry, Particle Image Velocimetry and Planar Laser Induced Fluorescence, and their applications to aerodynamics, propulsion, turbulent mixing flows, biofluid mechanics, environmental fluid mechanics and fundamental plume and jet studies. He has published more than 200 papers in archive journals and conferences. 20 PhD students and 12 MEng students have been graduated from his sole and joint supervision. He is ranked among the top 1.59% of the researchers in the category of mechanical engineering and transportation in 2021.

Professor Yu holds a Bachelor of Engineering (Hons), Associateship of the City and Guilds of London Institute (1987), Doctor of Philosophy and Diploma of Imperial College (1991) from Imperial College of Science, Technology and Medicine UK. His PhD studies were under the supervision of the late Professor J.H. Whitelaw FRS and were sponsored by the Royal Aircraft Establishment, Pyestock (UK).

He is a Chartered Engineer (UK), Fellow of the Institution of Mechanical Engineers (UK), Fellow of the Royal Aeronautical Society (UK), Fellow of The Hong Kong Institution of Engineers, Chartered Engineer in Transportation and Fellow of the Institution of Engineers, Singapore. He was a member in the IES Council (2018-2020) and is an independent assessor for CEng in various organizations.
