Biography

Wenwu has been with the Center for Vision Speech and Signal Processing, at University of Surrey, Guildford, UK, since May 2007, where he is currently a Lecturer. He also holds an RCUK Fellowship in machine audio perception. His research and teaching interests include blind signal processing, machine learning and perception, and machine audition (listening). During spring 2008, he has been a visiting scholar with The Ohio State University, Columbus, USA, working at (with sponsorship from) the Perception and Neurodynamics Lab and the Center for Cognitive Science.

Previously, from September 2006 to April 2007, he was with Creative Technology Ltd, as a Software R&D Engineer, at the Sensaura Division, Egham, UK, working on 3D positional audio technology for embedded systems and mobile devices. From May 2005 to August 2006, he was a DSP Engineer with Tao Group Ltd (now Antix Labs Ltd), Reading, UK, working on algorithm design for audio, music and video systems based on a real-time multimedia platform. Before that, he was a Postdoctoral Research Associate, from January 2004 to April 2005, with the School of Engineering, Cardiff University, Cardiff, UK, and from May 2002 to December 2003, with the Centre for DSP Research, King's College London, London, UK, working on blind signal processing for audio, speech and biomedical signals.

He received the B.Sc. degree in 1997, the M.E. degree in 2000, and the Ph.D. degree in 2002, all from Harbin Engineering University, Harbin, China, where he also received the Outstanding Graduate Award, the Excellent Paper Award, the Excellent Thesis Award and numerous Scholarships for academic excellence.

He is a member of the IEEE, and belongs to the IEEE Signal Processing, and Circuits and Systems Societies. He has served or currently serves as a reviewer, program committee member, or editor for a number of international journals and conferences. He was acknowledged as an Appreciated Reviewer for IEEE Trans. on Signal Processing in Jan 2008. He has been listed in Marquis Who's Who in the World (in both the 25th Silver Anniversary Edition in 2008 and the 26th Edition in 2009).

His research has been sponsored by the EPSRC, DSTL, RAEng, and the URSF.
