Research Interests

My PhD project examines the role of periodicity and aperiodicity (i.e., the contrast of voiced and unvoiced sounds) in speech perception. Tracking a target speech signal through a speech background appears to be affected by the periodicity of both the target and masker, with masking having a disproportionate effect for hearing impaired and Cochlear Implant (CI) users. We are investigating the abilities of listeners (normal hearing with and without simulations of CI processing, hearing impaired, as well as CI users) to perceive speech targets in the background of noise maskers in a variety of conditions mixing presence and absence of periodicity.

This PhD project is part of the INSPIRE network and includes collaborations with Torsten Dau (DTU) and Wanda Aleksy (RNTNEH).

I am also collaborating with Hannah Nash (UCL) in a project that compares letter-sound processing in dyslexic and normally developing children using behavioural and EEG methodology.

My background is in psychology, neuroscience and music. I have obtained a diploma in psychology from UC San Diego and FU Berlin, where I have worked in Stefan Koelsch’s group.
