Resume of Career

Tan Lee received his BSc and MPhil degrees in Electronics, and PhD degree in Electronic Engineering, all from the Chinese University of Hong Kong (CUHK), in 1988, 1990 and 1996 respectively. He is currently an Associate Professor in the Department of Electronic Engineering at CUHK, and the Director of the DSP and Speech Technology Laboratory.

Tan Lee has been working on speech and language related research since early 90s. He was a post-doctoral researcher at the Department of Speech, Music and Hearing, Royal Institute of Technology (KTH), Sweden, in 1997-1998. In 2001, he was a visiting researcher at AT&T Bell Laboratories, Murray Hill, USA. In recent years, Tan Lee has been collaborating closely with medical doctors, and speech and hearing professionals, to apply advanced signal processing methods in dealing with human communication disorder problems. He is the Director of the newly established Language and Communication Disorders Research Laboratory at CUHK Shenzhen Research Institute.

Tan Lee is a member of IEEE and a member of the International Speech Communication Association (ISCA). He is an Associate Editor of the EURASIP Journal on Advances in Signal Processing. In 2005-2006, Tan Lee served as the Chairman of the IEEE Hong Kong Chapter of Signal Processing. He was the Technical Program Chair of ICSPCC 2012, the Conference Chair of Oriental COCOSDA 2012, and the Finance Chair of the ISCSLP 2012.
