My research program is aimed at better understanding the nature of cognitive decline in different neurodegenerative diseases of the brain, as well as the brain changes that are associated with this decline. I have a specific expertise in Alzheimer's disease and atypical forms of dementia (primary progressive aphasias, posterior cortical atrophy, frontotemporal dementia). I am also interested in cognitive decline in individuals with Mild cognitive impairment (MCI). I also have a particular interest in cognitive changes in normal aging and how they are modulated beta-amyloid burden, vascular burden, and cognitive reserve.

More specifically, here are some of my research topics :

• Lexical and semantic disorders in Alzheimer's disease and semantic dementia (sv-PPA)
• Face recognition disorders in dementias and in acquired neurological disorders
• Brain changes associated with normal and pathological aging and how they are related to cognitive decline using different neuroimaging methods (PIB-PET, MRI, MEG)
• Cognitive intervention in older persons presenting with memory deficits

Le Dr Joubert a obtenu un PhD en neuropsychologie de l’Université de Montréal sous la direction du Dr. André Roch Lecours. Il a ensuite poursuivi sa formation postdoctorale dans le Service de Neurologie et de Neuropsychologie de l’Hôpital de la Timone avec le professeur Michel Poncet, et au sein du Laboratoire de Neurophysiologie et de Neuropsychologie de l’Équipe INSERM EMI 9926 (Marseille, France). Il est aujourd’hui chercheur au Centre de recherche de l’IUGM et professeur titulaire au Département de psychologie de l’Université de Montréal. Il est aussi membre de l’Ordre des psychologues du Québec.
