Resume of Career
Pak-chung Ching received the B. Eng. (1st Class Honors) and Ph.D. degrees from the University of Liverpool, UK, in 1977 and 1981 respectively. 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 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 Choh-Ming Li Professor of Electronic Engineering. 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. From 2006 till end of 2014, Prof Ching was appointed as Pro-Vice-Chancellor/Vice-President of CUHK. Between 2013 to 2014, Prof. Ching also took up the Directorship of the CUHK Shenzhen Research Institute. Prof. Ching is very active in promoting professional activities, both in Hong Kong and overseas. He was a council member of the Institution of Electrical Engineers (IEE), 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.
