We investigate the psychological and neurological foundations of human communication. When people communicate through speech, music or gesture, their brains must process a vast amount of sensory information. A primary goal of our research is to understand the neural mechanisms involved in processing the multisensory information that results from producing and perceiving verbal and nonverbal communication.

We conduct a wide range of studies on speech communication, singing, musicianship, and decision-making. We study both healthy individuals as well as individuals who are challenged by communication disorders caused by Parkinson's disease, autism spectrum disorder, and schizophrenia. The techniques we use include behavioural measures, EEG (electroencephalography), and fMRI.

Our goal is to develop a thorough understanding of these processes in order to improve the remediation of certain communication disorders and impact the design of communication technologies.

I am always seeking highly motivated individuals to join our research endeavours. Background in 1 or more of the following areas is ideal: psychology, neuroscience, biology, speech pathology, engineering, physics, applied math or computer science.

The Department of Psychology at Laurier has both a MSc and a PhD program in Cognitive Neuroscience, and accepts new graduate students each year.

Work conducted in the lab is related to CIHR, NSERC, and SSHRC supported areas of research.
