Biography

KOH SOO NGEE received both the BEng degree from the University of Singapore and the BSc degree from the University of London in 1979. He subsequently obtained his MSc and PhD degrees from Loughborough University, UK in 1981 and 1984 respectively. He joined Nanyang Technological University (NTU) of Singapore in 1985. He was the founding Head of the Communication Engineering Division of the School of Electrical and Electronic Engineering (EEE) of NTU from 1995 to 2005, and founding co-Chair of the International Conference on Information, Communications and Signal Processing. He is currently a Professor and Associate Chair (Academic) of the School. He has published more than 130 papers in international journals and conference proceedings, and holds two international patents on speech coder design. His research interests include speech processing, coding, enhancement and recognition, joint source-channel coding, audio coding, blind source separation and communication signal processing.
