​

Dr. Sara Tremblay is a professor in the Psychology and Psychoeducation department at Université du Québec en Outaouais, and a neuropsychologist certified by the Ordre des Psychologues du Québec. She is also an affiliated researcher at the Royal’s institute of Mental Health Research.

​

Dr Tremblay’s work uses approaches from both neuroimagery and neurophysiology to better understand the action mechanisms of neuromodulation methods, such as repetitive transcranial magnetic stimulation (rTMS). To be more precise, she studies how rTMS modifies cerebral activity of the cerebral metabolism and neural networks using positron emission tomography (PET), resting-state functional magnetic neuroimagery (fMRI) and TMS combined with electroencephalography (TMS-EEG). The studies contribute to improve rTMS paradigms and generate more reliable and efficient protocols for the treatment of psychiatric and neurological disorders. Dr. Tremblay’s second research axis aims at identifying neural predictors of the response to neuromodulation treatment in mental disorders. She seeks to develop objective neural measures of response to treatment in major depressive disorders, and identify specific neural profiles making an individual more susceptible to respond favorably to neuromodulation techniques as opposed to other treatments. As such, she uses methods from both neuroimagery and neurophysiology to monitor response to rTMS treatments.
