Pascale Tremblay, Ph. D.

Researcher, full Professor in Rehabilitation Sciences at Université Laval, and director of the Lab.

Pascale Tremblay is a full professor in the rehabilitation department at Université Laval, where she teaches in the speech-language pathology and audiology programs and acts as graduate research director for the M.Sc. and Ph.D. programs in rehabilitation sciences. She hold the Canada Research Chair (Tier 1) in the Neurobiology of speech and hearing.

At the crossroad of cognitive neuroscience, linguistics, gerontology and rehabilitation, Dr. Tremblay’s interdisciplinary research program aims to uncover the neurobiological mechanisms underlying the perception and production of speech and voice in adults, which are important building blocks of social interactions. Her work also focuses on understanding how aging affects speech and voice and, ultimately, aims to relate age-related communicative changes to age-related neurobiological changes in order to gain insights into underlying mechanisms. This knowledge is key to develop new innovative strategies to prevent, delay or even reverse the effects of aging on communication by inducing neuroplastic changes in the neurological circuits involved in speech and hearing processing, which is another focus of her research. Strategies under investigation include neurostimulation and the practice musical activities, especially singing, as well as other types of speech/vocal expertise. To achieve these goals, Dr. Tremblay and her team study the anatomy and functioning of the brain using state-of-the-art cognitive neuroscience methods such as functional, anatomical and diffusion brain imaging [MRI] as well as transcranial magnetic stimulation [TMS] and electroencephalography [EEG]. They also use modern behavioural and physiological approaches, such as bio-acoustical analyses of the speech signal, analyzes of speech errors, facial electromyography [recordings of muscle activity], measures of facial muscle force and endurance, respiration patterns, to study speech and voice mechanisms and to understand how these mechanisms evolve over the lifespan.

Lydia Gagnon

Research assistant, graduate student in speech-language pathology

Aware of the importance of communication in the human experience, Lydia is intrigued by language in all its components. Currently a Bachelor’s student in Language Sciences at Laval University, she wishes to better understand the complexity of this faculty’s disintegration during normal and pathological aging. Lydia believes that it is important that people are able to express their thoughts to the best of their ability. She is therefore also interested in learning Quebec’s sign language​.

Alexandre Sicard

Master student in rehabilitation sciences

Interested in science since high school, Alexandre found a particular interest in health sciences. Student during one year in the bachelor's degree in biopharmaceutical chemistry, he then completed a bachelor's degree in biomedical sciences. He thus began a master's degree in rehabilitation sciences. His project aims to investigate the effects of musical practice on brain health and cognitive abilities.

Research assistant, undergraduate student in linguistics

As a student in the bachelor's degree in language sciences of the Université Laval and a graduate in music from Cégep de Sherbrooke, Nathan is passionate about music and linguistics. His attraction for studying sound is confirmed by his interest in phonetics. Aiming for a Ph.D., Nathan's goal is to become a professor and researcher in that field.

David Ratelle

Graduate student in audiology and research assistant

How can such small disturbances in the air carry so much meaning for human beings? This is the big question that prompted David to undertake his master's studies in audiology at Laval University and to join the Speech and Hearing Neurosciences Laboratory. Preceded by a rich related experience, he holds a master's degree in interpretation from the Conservatoire de musique de Montréal, which he obtained with great distinction as a soloist and as a chamber musician. David has also shared his passion through music education, supported by master's studies in music education at UQAM, he has worked in the private and public sectors with students of all ages.

Philippe Prucha

Resident in diagnostic radiology

After completing a bachelor's degree in biology at McGill University I completed my medical studies at Université de Montréal in 2022. My interest for diagnostic imaging led me to pursue my residency in diagnostic radiology at Université Laval. My project in neuroimaging will attempt to establish a link between cerebral structural data obtained through MRI and cognition in a normal population.
