Education:
Post-doctorate in Neuropsychology and Brain imaging (Institut Universitaire de Gériatrie de Montréal, Université de Montréal) and Sleep disturbances (Hôpital du Sacré-Coeur de Montréal, Université de Montréal)
Ph.D. in Neuropsychology (Université du Québec à Montréal)
M.A. in Psychology (Université Laval)
Research Interests:
Sleep perturbations and cognition in normal and pathological aging.
More specifically, neurodegenerative disorders and their precursor stages (Alzheimer's, Parkinson's, Lewy body dementia, mild cognitive impairment, REM sleep behavior disorder) and some respiratory disorders (Chronic obstructive pulmonary disease, obstructive sleep apnea)
Methodologies:
Polysomnography, neuropsychological evaluation, electroencephalography (EEG), and neuroimaging (anatomic and functional)
