Current positions

Research Fellow in Speech Signal Processing


I am a 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.

Between March and October 2019, I worked on the EPSRC-funded Making Sense of Sounds project in the same research group. 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 the Chair of the Early Career Executive Board of UK Acoustics Network Plus, and a member of the Institute of Acoustics, the Acoustical Society of America and the International Speech Communication Association. I am on the UKSpeech Committee and the European Acoustics Association Technical Committee on Audio Signal Processing.

Research interests

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

Qualifications and Memberships

  • Member of the Institute of Acoustics
  • Full member of the Acoustical Society of America
