Career History

My BSc degree and PhD were in Physiological Sciences at the University of Newcastle upon Tyne, where I worked with Profs Gary Green and Adrian Rees.  I was then a post-doctoral fellow for 3 years at the University of Oxford, before coming to Aston University in 2001.

Research Interests

The majority of my research focusses on auditory processing, and understanding the potential mechanisms underpinning links between hearing and language development. 

I use both psychophysical and neuroimaging approaches, particularly magneto-encephalography (MEG) in all my research.  A core interest of mine is in the application of MEG to our understanding of clinical disorders, especially during childhood. Neurophysiological measures have great potential to advance our understanding of the causes of individual differences in sensory and cognitive processing, most notably in children and those with cognitive difficulties, where some behavioural measurements become inaccurate.  A key focus of my recent research has been to explore ways of computing sensory threshold from MEG measurements, for application to theories of sensory processing impairment in developmental disorders.

Another current activity is the development of software for measuring auditory psychophysical thresholds in children, and for other language-based measures, using the python programming language.

As Director of the Wellcome Trust Lab for MEG Studies in the ABC, I am involved in a range of projects using MEG, most notably a recent £1m project funded by the Wellcome Trust to address the challenges of using MEG technology with children.
