Prior to this, he was a Postdoctoral Research Associate at King's College London (from May 2002 to December 2003) and Cardiff University (from January 2004 to April 2005). He also worked in UK industry, first as a DSP Engineer at Tao Group Ltd (now Antix Labs Ltd) (from May 2005 to August 2006), then as an R&D engineer at Creative Labs (from September 2006 to April 2007). During spring 2008, he has been a visiting scholar at the Perception and Neurodynamics Lab and the Center for Cognitive Science, The Ohio State University. He is currently a member of the MoD UDRC in Signal Processing and the BBC Audio Research Partnership, as well as an associate member of Surrey Centre for Cyber Security. He obtained the PhD degree in April 2002 from Harbin Engineering University, China.

His current research interests include blind signal processing, sparse signal processing, audio-visual signal processing, machine learning and perception, and machine audition (listening). He has over 150 publications in these areas. He is a Senior Member of the IEEE, and belongs to the IEEE Signal Processing, Computational Intelligence, and Circuits and Systems Societies. He was a Local Arrangement Co-Chair of the 2013 IEEE International Workshop on Machine Learning for Signal Processing, an Area Chair of the 2012 European Signal Processing Conference (EUSIPCO), a Track Chair and Publicity Co-Chair of 2009 IEEE Statistical Signal Processing Workshop, Program Co-Chair of the 2009 IEEE Global Congress on Intelligent Systems. He has been a Session Chair for numerous conferences including 2012 IEEE International Conference on Acoustics Speech and Signal Processing (ICASSP) and the EUSIPCO 2012. He was a Tutorial Speaker on ICASSP 2013 in Vancouver, Canada, and of UDRC on Signal Processing summer school 2014 in Edinburgh, UK. He is currently an Associate Editor for IEEE Transactions on Signal Processing (since 2014).
