Overview
I originally trained as an Engineer and spent 17 years in the Semiconductor Industry developing and transferring worldwide state-of-the-art solutions for R&D and micro-chip manufacturing (at SPTS 1994-2010).
I then decided to undertake a PhD with Professor John Culling (between 2011 and 2015) with the ultimate goal of helping hearing impaired people (e.g., cochlear-implant users) to access noisy social settings. Our collaboration extended into two post-doctoral positions (between 2015-2019), including our "Turn an Ear to Hear" project and converting a physiologically-inspired model of the auditory periphery (MAP) into a sensorineural hearing impairment simulator. This simulator enabled the pioneering of differential diagnosis of sensorineural pathologies.
My research in auditory perception and background in engineering meant that it was natural to extend my research interests to human factors more broadly. I am now a member of the HuFEx and IROHMS groups as a lecturer in Human Factors. Since late 2019, I have helped to develop the research capability of our new IROHMS simulation lab, and contribute to many research projects cross-cutting the schools aligned to IROHMS. I teach on and coordinate the Human Factor's final-year module, supervise final-year projects and contribute to masters level training.

Research
Summary
My primary research interest is in finding new ways to help the hearing impaired better understand speech in the most challenging situations; i.e., when noise and reverberation conspire to make speech almost unintelligible. Every little helps: Every dB of improvement in speech-reception threshold counts. A collection of small benefits can make the difference between a unilaterally deaf person, a hearing aid user or a cochlear implant user, being totally isolated or happily involved in face-to-face conversations in noisy social settings. Our research has been based on two approaches: helping the hearing impaired make the best of the hearing they have; and improving sound coding so that it more faithfully transduces acoustical signals into the brain.
More recently, my research has involved projects at the heart of the Centre for Artificial Intelligence, Robotics and Human-Machine Systems (IROHMS) and the Human Factor Excellence Group (HuFEx). These projects are based on building the research capacity in the IROHMS' Simulation Laboratory (e.g. visual and auditory aspects of the 6m-diameter full immersion cylinder), and my chairing the IROHMS working group on "Ethical and Explainable AI”.
I was recently awarded an EPSRC DTP studentship to study "Rapid information integration in support of situational awareness and spatial behaviour". This project combines my interests in technology enabled perception, with a real-world problem of firefighters who face challenging emergency settings with impoverished sensory information. This research is in collaboration with Sabrina Cohen-Hatton, Chief Fire Officer of the West Sussex Fire and Rescue Services and Cardiff University Honorary Fellow.

Teaching
I have been engaged in teaching engineering and micro-technologies in the context of providing continuing education.
In the School of Psychology, I supervise final-year and masters projects; and I am the module coordinator of the final-year Human Factors module. This module has recently been expanded to 20 credits, which enables students to get a solid foundation in Human-factors psychology in the areas of safety and accident prevention, workload and situational awareness, automation and intelligent mobility, human-machine interface design and human-computer interaction, human-robot interaction, acoustics and hearing accessibility, cross-modal communication in heavy industries, and cyber psychology and security.
I also provide Swansea University Audiology Master students with a yearly lecture on cochlear implants.
