Andrew gained a BA in Psychology at Cardiff University in 2003. His PhD, 'Binaural Resolution,' was awarded in 2006 and involved measuring and modelling binaural temporal window durations and auditory filter widths.
Andrew's first postdoctoral position investigated research in the field of vision science, also at Cardiff University, assessing accuracy and precision of eye movements in the ageing population. He then worked as a Research Fellow at the Vision and Eye Research Unit (VERU) at Anglia Ruskin University. The project involved investigating how blind and low vision listeners made use of two acoustic distance cues (level and reverberation) to improve their spatial awareness, and how use of acoustic cues was enhanced among blind listeners. After this, he worked as a Research Associate at Cambridge University in Professor Brian Moore's research group, looking at auditory perception among hearing impaired and blind listeners. He is now a Visiting Fellow at Anglia Ruskin University.
Andrew is interested in how sensory impairment affects spatial awareness, and to what extent supra-normal performance for auditory spatial tasks among blind listeners, such as distance discrimination and azimuthal localization, can be explained by cross-modal cortical reorganization. His research uses virtualization techniques and self-report to investigate whether accurate internal representations of auditory space are formed in the absence of a visual signal, and under what conditions blind individuals demonstrate supra-normal hearing abilities. His work looks at spatial awareness and speech perception among hearing impaired and blind listeners, and how echolocation can be used to obtain information about a person's surroundings and guide locomotion.
Andrew is a member of the British Society of Audiology and Cambridge Neuroscience. He is a Visiting Researcher at Cambridge University.
