I'm currently an audio DSP research engineer at Creative Labs. I previously worked as a lecturer in Audio at the University of Surrey. I earned a BMus degree in Music & Sound Recording (Tonmeister) in 2007 and a PhD in Audio in 2011, both from the University of Surrey. My thesis was titled "A psychoacoustic engineering approach to machine sound source separation in reverberant environments".
