University of Huddersfield, UK

Biography:

I am a Senior Lecturer in Music Technology and Production and the leader of the Applied Psychoacoustics Lab (APL) at the University of Huddersfield. I teach acoustics/psychoacoustics, recording techniques, research methods and audio signal processing. My research primarily concerns the modelling of perceptual mechanisms for various auditory attributes in relation to sound recording and reproduction, and the development of “perceptually motivated” new music technology algorithms. Recent projects include the developments of interactive and 3D microphone array techniques, perceptually motivated time and level panning methods, and the investigation into the perception of 3D sound. I am currently undertaking an EPSRC-funded research project “Perceptual rendering of vertical image width for 3D multichannel audio” as Principal Investigator, and supervising various post-graduate research projects on auditory perception and psychoacoustic engineering (see Research Degree Supervision). 

Before joining Huddersfield in 2010, I was a Senior Research Engineer at LG Electronics in South Korea. I led a project to develop audio post-processing algorithms for LG mobile phones and actively participated in the standardisations of new MPEG audio codecs.

I graduated from the music and sound recording (Tonmeister) course at the University of Surrey in 2002. During the course I spent my placement year as an assistant engineer at Metropolis studios in London. I gained my PhD from the same university in 2006. My PhD research was concerned with the subjective effects and objective measurements of interchannel crosstalk in multichannel microphone techniques. 

I am also an experienced freelance sound engineer/producer working in a wide range of musical genres, including classical, jazz and rock. My speciality is stereo and surround acoustic recording using microphones. 

Outside the University work, I am an active member of the Audio Engineering Society (AES). I am a member of the AES Technical Council, and a regular reviewer of the AES journal. I am also serving as an Editorial Board Member for the AES/Focal Press book series.
