Current positions
Research Fellow
Biography
I am a Senior Research Fellow in Speech Signal Processing on the Engineering and Physical Sciences Research Council (EPSRC) funded project, Clarity: Challenges to Revolutionise Hearing Device Processing, in the Acoustics Research Group. I am also a Senior Research Fellow on the Cadenza Project on signal processing to improve music listening for users of hearing aids. I am one of the leads for the Wellbeing theme in the UK Acoustics Network Plus (UKAN+), where I also lead the Early Career Special Interest Group. I am also the Vice President of the International Speech Communication Association (ISCA) Special Interest Group on Speech and Language Processing for Assistive Technologies (SIG-SLPAT).
Between March and October 2019, I worked on the EPSRC-funded Making Sense of Sounds project, also in the Acoustics Research Centre. This role built on my expertise in audio, acoustics, and signal processing outside of the speech domain. It combined psychoacoustics, soundscapes, digital signal processing of audio and pupil dilation response signals, spatial audio and machine learning.
Previously, I was a Research Associate at the Acoustics Research Unit (ARU) at the University of Liverpool, working with Professor Carl Hopkins. I conducted research primarily in the areas of speech intelligibility, speech enhancement, and speech privacy, with a focus on highly degraded signals.
I am a member of the Institute of Acoustics, the Acoustical Society of America and ISCA. I am on the UK Speech Committee and the European Acoustics Association Technical Committee on Audio Signal Processing.
Areas of Research
Speech intelligibility, privacy and security; speech enhancement; speech signal processing for hearing aids; subjective evaluation of speech and audio, psychoacoustics; effects of noise and room acoustics on speech; general speech and audio signal processing; soundscapes; listening effort/difficulty; machine learning for audio/speech
