Dr Chandratilak De Silva Liyanage


Professor, Faculty of Integrated Technologies



Professor Liyanage C De Silva received BSc Eng (Hons) degree from the University of Moratuwa Sri Lanka in 1985, MPhil degree from The Open University of Sri Lanka in 1989, MEng and PhD degrees from the University of Tokyo, Japan in 1992 and 1995 respectively. He was with the University of Tokyo, Japan, from 1989 to 1995. From April 1995 to March 1997 he pursued his postdoctoral research as a researcher at ATR (Advanced Telecommunication Research) Laboratories, Kyoto, Japan. In March 1997 he joined The National University of Singapore as a Lecturer where he was an Assistant Professor till June 2003. He was with the Massey University, New Zealand from 2003 to 2007. Currently he is the Professor of Engineering and the Deputy Dean of the Faculty of Integrated Technologies http://fit.ubd.edu.bn at the University of Brunei Darussalam.

Liyanage has published over 160 technical papers in these areas in international conferences, journals and Japanese national conventions and holds one Japanese national patent, which was successfully sold to Sony Corporation Japan for commercial utilization, and he holds 1 US and 1 Brunei patents. Liyanage’s works have been cited as one of the pioneering work in the bimodal (audio and video signal based) emotion recognition by many researchers. His papers so far have been cited by more than 2000 times (according to scholar.google.com) with an h-index of 20.

He received the Best Student Paper Award from SPIE (The International Society for Optical Engineering) for an outstanding paper contribution to the International Conference on Visual Communication and Image Processing (VCIP) in 1995. He also received National University of Singapore, the Department of ECE Teaching commendation award in 2001 and 2002 consecutively.

He is a senior member of IEEE USA and the interim chair of IEEE Brunei Darussalam Subsection. He was the General Chair of the 4th International Conference Computational Intelligence and Robotics and Autonomous Systems (CIRAS2007) held in New Zealand. http://scholar.google.com/citations?user=utF5BG0AAAAJ&hl=en
