From 1981 to 1982  he was Research Officer at the University of Bath, UK. In 1982, Prof. Ching returned to Hong Kong and joined the then Hong Kong Polytechnic University as a lecturer. Since 1984, he has been with the Department of Electronic Engineering of the Chinese University of Hong Kong (CUHK), where he is currently a chair professor. He was Department Chairman from 1995 to 1997, Dean of Engineering from 1997 to 2003 and Head of Shaw College from 2004 to 2008. He became Director of the Shun Hing Institute of Advanced Engineering in 2004. Beginning August 1 2006, Prof Ching assumes his new responsibility as Pro-Vice-Chancellor of CUHK. Prof. Ching is very active in promoting professional activities, both in Hong Kong and overseas. He was a past chairman of the IEEE Hong Kong Section, an associate editor of the IEEE Transactions on Signal Processing from 1997 to 2000 and IEEE Signal Processing Letters from 2001 to 2003. He was also a member of the Technical Committee of the IEEE Signal Processing Society from 1996 to 2004. He was appointed Editor-in-Chief of the HKIE Transactions between 2001 and 2004. Prof. Ching has been instrumental in organizing many international conferences in Hong Kong including the 1997 IEEE International Symposium on Circuits and Systems where he was the Vice-Chairman, and the IEEE International Conference on Acoustics, Speech and Signal Processing where he was the Technical Program Chair. In addition, Prof. Ching also plays an active role in community services. He is presently Member of the Governing Council of the Hong Kong Quality Assurance Agency, Panel Member of the Research Grant Council and Member of Copyright Tribunal. He was Member of the Consumer Council and Chairman of the Hong Kong Accreditation Advisory Board from 2000-2006 and Member of Electrical Safety Advisory Committee of the Electrical and Mechanical Services Department from 2002-2008. Prof. Ching is also a Guest Professor at the Beijing University of Posts & Telecommunications, Huazhong University of Science & Technology, Southeast University and Institute of Acoustics, Chinese Academy of Sciences.
