Carl Verschuur

BA, MSc, RCS, PhD

Primary position:
Lecturer in Audiology

Carl is a lecturer in audiology with a mixed portfolio of teaching, research and administration in a range of aspects of audiology and hearing science. He was originally trained as a clinical audiologist and worked in clinical and management jobs in the NHS. Since arriving at the ISVR in 1999, he has worked both as a clinical scientist and lecturer in audiology. He is now responsible for running the master’s programme in Audiology and has overall responsibility for Audiology teaching at the ISVR. As well as contributing to research, teaching and administration, he supervises a number of students at undergraduate, postgraduate taught and doctorate level.

Research Interests

There are two overlapping research questions which drive Carl’s research activity. The first is the question of what aspects of the speech signal should be enhanced for individuals with hearing impairment, in particular where individuals have low frequency residual hearing which can be combined with cochlear implant stimulation. Related to this is the question of which “landmarks” in the speech signal should be emphasised to improve speech perception in those with hearing impairment. The second question is how the basic biology of the individual and the cochlea, particularly the role of inflammation and the immune response, impacts on hearing loss and the possibility of hearing preservation, particularly with ageing but also for those undergoing cochlear implant surgery where preservation of residual low frequency hearing is critical.
