BSc (Hons), DPhil
My research interest is the neurobiology of speech and language with a particular focus on developmental stuttering.
Throughout my DPhil at Oxford I contributed to a large randomised control trial looking at whether tDCS can enhance fluency in people who stutter (INSTEP trial - see website). Within this, I used a range of techniques to investigate the neural control of speech and the differences between people who stutter and people who are typically fluent. For example, I used a recently developed technique - vocal tract Magnetic Resonance Imaging (vtMRI) - to view the precise movements of speech articulators (such as the tongue and vocal chords) within the vocal tract. I also used functional MRI to investigate the neural control of inhibition during speech and non-speech movements. Finally, I used brain stimulation techniques (transcranial magnetic stimulation (TMS) and tDCS) to understand whether tDCS has the potential to modulate speech motor control in a typically speaking population.
Having finished my DPhil, I am now continuing to work on the analysis of the INSTEP randomised control trial.
