About my research

My primary research interest is speech intelligibility. I did my undergraduate studies at the University of Toronto Mississauga, double-majoring in Biology and Psychology. During this time, I was part of the Child Language and Speech Studies (CLASS) lab, and investigated infants' ability to perceive speech in noise. From there, I completed my MSc in Health and Rehabilitation Sciences at UWO, where I examined the effect of botulinum toxin A (e.g., Botox) treatment on speech intelligibility in individuals with oromandibular dystonia.

I joined the CoNCH lab to research how voice familiarity improves speech intelligibility in noisy environments. Previous work shows that experience with a voice can help listeners understand speech when a competing talk is present. The goal of my PhD is to develop a deeper understanding of how familiar voices improve intelligibility and determine if the brain represents familiar and unfamiliar voices differently.
