In 1991, he joined the Hong Kong Polytechnic University as a Research Associate, and 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 150 international journals and conference papers. His research interest includes wavelets theory, 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 rate as Excellent by the Hong Kong Research Grants Council. He and his research students have also received three best paper awards in international conferences. During his sabbatical leave in 2006, Dr Lun joined the University of Windsor in Canada as the Visiting Scholar and gave several seminars in the University of Windsor as well as the University of Missouri Columbia in the USA.

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 Chair of 2004 International Symposium on Intelligent  Multimedia, Video and Speech Processing (ISIMP 2004), and General Co-Chair of 19thInternational Conference on Digital Signal Processing (DSP 2014). He was also the 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).
