Lun received his B.Sc.(Hons.) degree with 1st Class Honours from the University of Essex, U.K., and PhD degree from the Hong Kong Polytechnic University (formerly called Hong Kong Polytechnic) in 1988 and 1991, respectively. In 1991, he joined the Hong Kong Polytechnic University. He was the Interim Head of the Department of Electronic and Information Engineering from 2013-14 and 2016 -2019. He is now an Associate Professor and Associate Head of the Department of Electronic and Information Engineering. He is also the leader of the Engineering Doctorate programme in the area of Electronic and Information Engineering.

Dr Lun has published more than 170 international journals and conference papers. His research interest includes signal and image enhancement, computational imaging, and deep neural networks. One of his research projects "A study of the Computer Tomography and the Wavelet Transform" was rated as Excellent by the Hong Kong Research Grants Council. He and his research students have received three best paper awards in international conferences. His works also received the Gold Medals from 71st  International Trade Fair for Ideas, Inventions & New Products (iENA) in 2019 as well as Salon International Des Inventions Genève in 2021.

Dr Lun is active in professional activities. He was the Chairman of the  IEEE Hong Kong Chapter of Signal Processing in 1999-00.  He was the General Co-Chair of 2020 IEEE International Conference on Visual Communications and Image Processing (VCIP 2020), General Co-Chair of 19th International Conference on Digital Signal Processing (DSP 2014), and General Chair of 2004 International Symposium on Intelligent  Multimedia, Video and Speech Processing (ISIMP 2004). He was the Technical Co-Chair of 2022 International Workshop on Advanced Image Technology (IWAIT 2022), Technical Co-Chair of 2015 APSIPA Annual Summit and Conference (APSIPA ASC 2015), and Technical Co-Chair of 2015 IEEE 20th International Conference on Digital Signal Processing (DSP 2015). He was the executive committee member of a number of other major conferences in the area of signal and image processing including 2003 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP 2003), 2010 IEEE International Conference on Image Processing (ICIP 2010), and 2017 IEEE International Conference on Multimedia and Expo (ICME 2017). He received the Certificate of Merit from the IEEE Signal Processing Society for dedication and leadership in organizing the 2010 IEEE  International Conference on Image Processing (ICIP). For his experience in academic program planning and administration, Dr Lun was invited by the Hong Kong Council for Accreditation of Academic & Vocational Qualification to serve as a panel member for the validation of a few local undergraduate programmes since 2005.

He was the Editor of HKIE Transactions published by the Hong Kong Institution of Engineers (HKIE) in the area of Electrical Engineering. He was also the leading guest editor of a special issue of EURASIP journal of Advances in Signal Processing. He was an Associate Editor of IEEE Signal Processing Letters and IEEE Open Journal of Circuits and Systems. He is a member of the IEEE Circuits and Systems Society Digital Signal Processing as well as Visual Signal Processing and Communications Technical Committees.

Dr Lun is a Chartered Engineer, a fellow of IET, a corporate member of HKIE and a senior member of IEEE.
