Prior to that, he was Senior Scientist and Technical Manager, Singapore Institute of Manufacturing Technology (1992-2006); Adjunct Associate Professor, National University of Singapore (1998-2006); Research Fellow, Brunel University (1990-1992) and Durham University (1989-1990).

XiaoQi is a strong advocate for translating fundamental and applied research into industrial applications. His team received Singapore National Technology Award (1999) for their work on Maintenance Repair and Overhaul (MRO) of high pressure turbines. He was awarded New Zealand Forest Owners Association Award (2015) for the development of forest harvest robot. His novel work on untethered wall climbing robot span off Invert Robotics Ltd that won New Zealand Hi-Tech Start-Up Excellence Award (2012). He has more than 400 publications, 10 patents, and authored and edited 4 books. He has delivered over 100 invited keynote addresses and seminars.
