I have a long-standing interest in elucidating how humans communicate via variations in air pressure, more commonly known as "sounds". This interest resulted in my completion of a doctoral degree in linguistics at Universite de Montréal, where I studied both perception and production of speech. In particular, I examined the physiological, psycholinguistic, and neurolinguistic correlates of structural prosody. Subsequently, I completed post-doctoral training in psychology and communication sciences and disorders at McGill Univeristy, where I continued examining speech communication, using a variety of other methods and techniques. My current research goal is to examine what is specific to speech processing itself versus what can be explained by domain-general (physiological or cognitive) constraints. My other academic interests include speech acquisition, language evolution, forensic applications of acoustic phonetics, and teaching.

My research focuses on sensorimotor integration and learning in speech production. Currently, I am attempting to differentiate online control processes, which involve moment-to-moment responses to perceived errors or divergence in speech output, from sensorimotor learning processes, which involve changes in response over time. In particular, I am proposing that these two processes are behaviourally distinct, and are served by overlapping but distinct brain networks.

Techniques used in my projects have included functional magnetic resonance imaging (fMRI) and inhibitory transcranial magnetic stimulation (TMS) during the performance of various speech production tasks. Going forward, I will be conducting both task-based and resting-state magnetoencephalography (MEG) to address issues of timing and plastic brain connectivity involved in my research.

The tasks used during my studies are typically variations on speech perturbation tasks, in which the first formant (F1) of a participant's speech is perturbed upward or downward during production of consonant-vowel-consonant syllables. The perturbed speech is fed back to the participant through headphones in real-time, creating the illusion that the participant has misspoken. This may cause a compensatory response. Various parameters of the task are altered according to the needs of the study.

I'm interested in using electrophysiological and eyetracking methodologies to further investigate how we perceive and produce language. My broad research interests include the interaction between the underlying mechanisms of speech perception and production, the integration of various acoustic cues for perceiving speech, and the plasticity of the speech perception and production systems. Additionally, I'm interested in how these processes are affected by aging.

My research interests include the dynamic of language processing and its neurocognitive basis, especially at the morpho-syntactic and semantic levels. I’m currently working on verb particle construction processing by French-English bilinguals.

My research interest focuses on how adults learn novel articulatory movements required for production of non-native sounds. I am especially interested in how principles of optimal training conditions for limb motor learning (‘principles of motor learning’) can be applied in second language speech production.
