Professor Lu, Ng Chun-Man Endowed Professor in Orthopaedic Bioengineering, obtained his PhD degree and the “Distinguished Graduate Award” from the University of Waterloo, Canada, in 1994. He joined the Department of Orthopaedics & Traumatology, The University of Hong Kong (HKU) in 1995 as an Assistant Professor and was promoted to Associate Professor in 2001, and full Professor in 2009. He established Orthopaedic Research Centre in 1995 and has served as director since then. Professor Lu has specific experience in the areas of Orthopaedic Biomechanics, Biomaterials, 3-D Bioprinting-technology as well as Clinical Bioengineering teaching and research. He has achieved substantial international recognition in the area of bioengineering and is widely acknowledged as top 1% scholars (2009-2018) according to ISI’s Essential Science Indicators. Professor Lu has consistently secured a significant proportion of the research funding of HK$57 millions from Hong Kong and RMB55 millions from PR China in his areas of activity from a number of major funding bodies, including as chief scientist of the National Key R&D Programs, funded RMB27.44 millions in 2019 by the Ministry of Science and Technology (MoST). He held a number of patents for his innovations and has published more than 290 papers in international Peer Reviewed Journals, with more than 10,000 citations and H-index 55.
