Jez graduated with a BMus in Music and Sound Recording from the Tonmeister course at the University of Surrey in 1994. Following time spent as a freelance recording engineer, music technology lecturer and working for Digital Audio Research and Fairlight he began an MSc in Music Technology at York in 2000, graduating a year later. He gained his PhD, on 'Real Time Spectral Modelling of Audio for Creative Sound Transformation', in 2006 and now works in the department as a lecturer in Music Technology as well as undertaking occasional work as a recording engineer and consultant. He was previously a teaching fellow in the department for undergraduate and postgraduate courses and, subsequently, a research associate in Room Acoustics Modelling. He teaches (or has taught) Acoustics and Psychoacoustics, Recording Studio Techniques and Technologies, Advanced Post Production Techniques, ECAD for Music, Advanced Music Technology Systems, Advanced Digital Synthesis, Hearing and Voice, Music Technology Creation and Perception, Music Technology in Action, Audio Algorithm Design and Implementation and Physical Modelling Synthesis, Music Technology Portfolio, Advanced Multimedia Applications and Speech Processing. He is Deputy Director of the Department's Graduate School.
Outside of his work on acoustic modelling his other research interests are real-time spectral modelling of audio and advanced audio modelling and processing for studio based effects processing, particularly directional separation of microphone signals. He has recently supervised Bachelors and Masters projects on audio processing with the two-dimensional Fourier transform, the impact of processing for live DJing on the quality of mp3 files, transcribing the music of Debussy to 19 and 31 TET tuning systems, physical modelling in PD, automated audio mixing tools, tempo perception, principal component analysis of rasterised audio, modelling of weakly non-linear systems for audio, modification of human voice characteristics and spectral modelling of guitar distortion.
He is currently a Royal Academy of Engineering Public Engagement Fellow.
