My major research focus includes the study of neuropsychiatric symptoms in dementia, specifically delusions and their neurocognitive/neurobiological correlates. I also have an interest in functional outcome studies in dementia, examining the impact of cognitive decline on real world activities such as driving, etc. As well, I have an interest in understanding how cognitive reserve (education, art, bilingualism) protects against development of dementia. Finally, I have an interest in health system issues as they apply to the elderly.
