Dr. Wiltshire's research aims to understand the neural control of speech production, with a specific interest in developmental stuttering. 

During her postdoctoral fellowship at the Institute for Phonetics and Speech Processing, Ludwig-Maximillains-University (LMU), Munich she combined brain stimulation techniques (Transcranial Magnetic Stimulation) and articulography (Electromagneticarticulography, vocal tract MRI) to investigate the neural processes underlying the initiation and inhibition of speech movements in people who stutter and people who are typically fluent.

Dr. Wiltshire completed her DPhil at the University of Oxford in 2020, with Kate Watkins. During her DPhil, she contributed to a large randomised control trial looking at whether tDCS can enhance fluency in people who stutter (INSTEP trial). Within this, she used a range of techniques, including tDCS, TMS and brain and vocal tract MRI, to investigate the neural control of speech in people who stutter and people who are typically fluent.
