P(a)ediatric auditory cognitive neuroscience.
I am a cognitive psychologist working in the Division of Psychology and Language Sciences at University College London. I am currently working on comparing different measures of listening effort and developing faster methods of assessing the frequency following response for clinical applications.
I am interested in the effect of everyday hearing technology (e.g. hearing aids, earbuds with remote microphone apps) on language, cognition, academic ability and cortical acclimatisation in children with normal hearing and hearing impairment.
I use neuroimaging techniques, EEG and MRI, to understand the underlying mechanisms of speech and non-speech listening skills in hearing impairment and developmental disorders.
I am also exploring how to bring gamification and virtual reality to make the research and clinical audiological environment more child-friendly.
