Research Interests

My PhD project examines the effects of ageing and hearing impairment on speech perception in noise. A common complaint among older adults, whether hearing impaired or not, is that they experience increased difficulty understanding speech in noisy environments. The goal of my PhD project is to understand to what extent difficulties in perceiving speech in the presence of background noise can arise from deficits in auditory encoding at the first neural stages of the auditory pathway. This question is addressed by measuring auditory brainstem responses to speech sounds in quiet and in noise.

More generally, my research interests are speech perception in noise, ageing, hearing impairment, speech perception using cochlear implants, auditory neuroscience, auditory processing, and cognitive hearing science.

I previously completed a BA in English Language and Literature at the University of Groningen. I also hold an MA Linguistics from Utrecht University and an MRes Speech Language and Cognition from UCL.

My PhD project is funded by Action on Hearing Loss and Age Uk.
